American Made Drill Bits

Drill bit production takes place at Bad Dog Tools' facility at 24 Broadcommon Rd in Bristol, RI, the company's only manufacturing site (company-sourced claim, matching its product-page statement that bits are made "right here in our facility in Bristol, RI"). Production includes shaping the armor-steel shanks and brazing the Carbaloid tips to them by hand. The company does not disclose the origin of its raw steel or of the tungsten-carbide-based tip material on its site, and no independent sourcing records were found either confirming domestic origin or documenting foreign sourcing for these inputs — this is a gap in the public record rather than a resolved finding in either direction.

Company history and founder details come from Bad Dog Tools' own About Us page, with no independent (non-company) confirmation of the founders' names located. Current manufacturer status and facility address are corroborated by three independent sources — The Blue Book industry directory (which categorizes the company under manufacturers), ZoomInfo's industry classification, and a Loc8NearMe business listing describing it as a "family owned manufacturer" — in addition to the company's own site. The "Made in the USA" claim language matches verbatim between the company's own product pages and its Amazon storefront listings. Brazing temperature and tip-material composition are sourced only from the company's own listings; no trade press or lab confirmation of these specs was found. No evidence of offshore production steps was found for the drill bit line, though raw material origin (steel, carbide) remains undisclosed by the company.

Chicago-Latrobe bits are produced at Greenfield Industries' Seneca, SC facility (2501 Davis Creek Road), which has been in continuous operation since 1961 and also serves as company headquarters. Greenfield operates two additional facilities, in Mississauga, Ontario and Mexico City, Mexico, which are not part of the USA-made product line. The company does not publish the country of origin for its high-speed steel or cobalt raw stock; no evidence of offshore finishing or assembly steps was found for this brand as of this verification, but raw-material origin remains undisclosed rather than confirmed domestic.

Current ownership and the 2023 Walter Surface Technologies acquisition are confirmed on Greenfield Industries' own site (gfii.com/about/history) and independently corroborated by trade press coverage in The Fabricator and Cutting Tool Engineering. The Seneca, SC facility's manufacturing status and 1961 start date come from an industrial buying group's supplier announcement (IBC), independent of Greenfield's own marketing. Product line names, materials, and finishes are drawn from current retailer listings (MSC Industrial, Amazon, Newegg, USA Tool Depot); the NAS 907 aerospec claim specifically traces to retailer copy, not to Greenfield directly. The "Made in USA" claim itself is sourced to Greenfield's own marketing (GFII "What's Happening" page, company YouTube channel) and is corroborated by a third-party reseller's description of physical "Stamped USA" markings on individual bits.

Eagle Tool US manufactures at its Crystal Lake, Illinois facility, where the company states roughly 90% of production is performed in-house, from raw steel through finished bit. Steel stock is domestically sourced. Heat treatment, powder coating, and blackening are outsourced to third parties, but the company states this work is kept within the US; the Allen wrench sold with the Switch Bit system is likewise purchased from a third-party supplier that the company requires to manufacture domestically. Sourcing of the carbide used in the company's carbide-tip bit line could not be confirmed as domestic or imported from any available source.

Company history and York's founder/president status are confirmed through a 2014 Pro Tool Reviews interview conducted with York and staff, corroborated by York's current LinkedIn profile. The Crystal Lake facility address is confirmed through Yellow Pages and Yahoo Local business directory listings, both of which classify Eagle Tool US as a manufacturer rather than a distributor. The domestic-steel and in-house-production figures, along with the outsourced heat-treat/coating detail, come from that same Pro Tool Reviews interview rather than company marketing copy. The "Made in USA" claim itself, including the company's stated FTC compliance language, is drawn from the company's own site and current Amazon product listings.

The company states that its drill bits and cutting tools are manufactured at its Loganville, Georgia operations, but the address on file — a suite at 3785 Harrison Rd SW — is classified by Google Business as a "Tool wholesaler" location rather than a manufacturing facility, and no independent source (trade press, local news, business directory listing a manufacturing SIC/NAICS code, or documented factory address) confirms an owned/operated production site. No information is published on the origin of the tool steel or carbide used in KnKut products, and no offshore sourcing has been confirmed — but the absence of any confirmable domestic production facility means the underlying claim can't be verified either way at this time.

Company history and product-line specifics come from knkut.com's own product and About pages, which is the only source for the founding narrative, material specifications (HSS/Vanadium content, nitride and gold treatments), and the Rockwell hardness rating on carbide-tipped bits — none of that is independently corroborated. The Loganville address and its "Tool wholesaler" business classification come from Google Business listings, cited independently in a Practical Machinist manufacturing-trade forum thread (May 2025) that raised the same manufacturer-vs-reseller question addressed here. No trade press, local news, or business directory recording a manufacturing facility, square footage, or production-site employee count could be located as of this July 30, 2026 check.

Kodiak's own site labels individual drill bits "Made in USA" but does not disclose a production facility address, square footage, employee count at a plant, or any manufacturing process detail (grinding, heat treatment, blank sourcing) anywhere on the site. The Syracuse, NY address tied to the company's state filing and website functions as its registered business address; no independent source confirms it as, or identifies elsewhere, an owned/operated drill bit manufacturing plant. Given the company's parallel business of reselling other manufacturers' branded tools, buyers should treat the "Made in USA" claim on Kodiak-brand drill bits as the company's own representation rather than an independently verified manufacturing fact. No evidence of offshore sourcing for Kodiak-brand drill bits was found as of this review, but that absence should be read alongside the absence of confirmed US production — neither can be independently verified from available sources.

Company formation date and registered address: New York Department of State, Division of Corporations filing record (document #4166361), accessed via third-party filing aggregator. Manufacturer/reseller classification: IndustryNet industrial directory listing. Product line, materials, and "Made in USA" claim language: Kodiak Cutting Tools' own site (kodiakcuttingtools.com), About Us and individual drill bit product pages, current as of July 30, 2026. No independent third-party confirmation (trade press, local news, facility audit) was located for any Kodiak-brand production facility; this gap is the basis for the Brand/Reseller and Unsubstantiated/Unclear labels above.

Montana Brand products are engineered and produced at Rocky Mountain Twist's Ronan, Montana headquarters and manufacturing facility (RMT-reported size: 300,000 sq ft), the company's sole production site. Manufacturing processes on-site include CNC drill grinding, high-speed machining, metal forming, stamping, die casting, and injection molding, alongside RMT's in-house cryogenic treatment line.

Ownership and founding history are corroborated across SEC 8-K filings from the Jore Corporation bankruptcy, contemporaneous Missoulian/MATR local news coverage of the 2002 asset sale, and a 2022 John Force Racing sponsorship release confirming Frank Tiegs as current owner — independent of Montana Brand's own marketing. The manufacturer relationship (Montana Brand products made by Rocky Mountain Twist) is stated on Montana Brand's own "About Us" page and confirmed by USPTO trademark records showing Rocky Mountain Twist Corporation as the trademark holder. Facility size, process details, and the cryogenic treatment claim originate from RMT's own site and are not independently confirmed by third-party reporting or trade press; the specific country of origin for raw steel stock is not disclosed by the company in any source reviewed. Current operating status is confirmed via active 2025 job postings for the Ronan facility and active USDOT motor carrier registration as of late 2025.

Production takes place at Viking Drill & Tool's single manufacturing facility, 355 State Street, St. Paul, Minnesota — the same site serves as corporate headquarters. The company states its cutting tools are designed and engineered in-house, with grinding, fluting, and heat treatment performed at this plant. The company's own tagline describes products as "Proudly Manufactured in the USA with globally sourced materials," an explicit acknowledgment that raw tool steel and/or components are imported before domestic machining and finishing; no source country is disclosed for that material. All materials are stated to meet National Aerospace Standard (NAS) 907. Buyers should note that the broader Viking/Norseman/CTD trademark family sells a mixed catalog under different sub-brand names, and at least one non-drill-bit product (carbon-steel taps sold under the Viking name) has been reported by a customer as Chinese-origin — a report specific to that product line, not to Norseman-branded drill bits.

The 1951 founding date and St. Paul facility address are confirmed identically on both norsemandrill.com and vikingdrill.com. The Norseman trademark's ownership by Viking Drill & Tool, Inc. is confirmed by USPTO registration (No. 4579528) via Justia Trademarks — a federal record, not company marketing. The company's Manufacturer status rests on ZoomInfo's aggregator-sourced employee count and Indeed employee reviews describing on-site production work, since no trade-press facility profile was found. The "globally sourced materials" origin language is drawn directly from current company copy on both sites. The Chinese-origin tap report comes from a single 2018 consumer forum thread and is not independently verified; it is disclosed here because it involves the same legal entity, not because it has been confirmed to apply to Norseman-branded drill bits.

ProMAXX offers these drill bits under a "Made in the USA" claim and states the cobalt tooling is "machined turned right here in the USA." The company does not publish a separate production-facility address, square footage, or equipment list for this line beyond its Pittsburgh, PA headquarters suite, and its own "About Us" page qualifies its domestic-manufacturing claim by stating products are made in the USA "nearly all by ProMAXX Tool" — language that acknowledges some portion of its catalog is not produced in-house. No evidence of offshore sourcing (imported steel, overseas-machined components) was found for the drill bit line specifically as of this verification.

Company history, founding date, and headcount were sourced from PitchBook's company profile; the ownership change was independently confirmed across five separate trade-press outlets (Vehicle Service Pros, Aftermarket News, TechShop Mag, Aftermarket Matters, and Milton Industries' own release), though their "designer and manufacturer" characterization traces back to the same company-issued press release rather than independent reporting. Product material specifications (M42 cobalt, split-point geometry, Rockwell C55 rating) are sourced from ProMAXX's own product pages and matching retailer listings (Amazon, ToolSource, ToolWeb). The "nearly all by ProMAXX Tool" qualifier and the absence of a distinct facility address are both drawn directly from ProMAXX's own site; no third-party source (local news, industry directory, facility listing) was located to independently confirm or contest a dedicated production facility for this product line.

RMT's headquarters and sole production facility is a 300,000-square-foot plant at 34837 Innovation Dr., Ronan, Montana, at the base of the Mission Mountains. The company states its manufacturing processes include CNC drill grinding, high-speed machining, die casting, injection molding, metal forming, and stamping — the equipment set needed to take raw stock through fluting, pointing, and coating in-house rather than outsourcing those steps. No evidence of offshore or outsourced production was found as of this verification date: no imported raw materials, no offshore-manufactured components, and no fully-imported product lines were identified within RMT's drill bit catalog.

Company history, ownership, and facility details come from Rocky Mountain Twist's own site (rockymountaintwist.com/pages/about-us-1), which is the sole source for the specific manufacturing processes listed and for the unqualified "U.S. Manufacturer" claim. The Frank Tiegs ownership claim is corroborated independently through John Force Racing sponsorship press releases (2019, 2022) and Dragzine racing coverage — trade press, not company marketing. The Ronan facility's existence and address are cross-confirmed through the FMCSA's SAFER carrier database (DOT #731308), which also shows an active registration as of September 2025, indicating the company remains an operating entity. Current "Made in USA" status for the drill bit catalog specifically is independently corroborated by MSC Industrial Supply's product listings, which tag Rocky Mountain Twist drill bits "Made in USA: Yes" across its full catalog rather than relying on RMT's own claim alone.

Spyder offers no public information on where its Mach-Blue bits are physically produced — no facility address, square footage, or third-party facility coverage was found, and the company's own site does not identify a plant. Given the company's small size (single-digit-to-low-teens employee count per business databases) relative to the scale needed to run steel grinding, fluting, and heat-treatment lines for national retail distribution, actual production is more likely performed by a contracted US manufacturer on Spyder's behalf rather than in a Spyder-owned facility. Buyers should treat "Made in USA" here as Spyder's claim about the finished bits' domestic origin, not as evidence Spyder itself runs the factory.

The USA-origin claim for Mach-Blue/Stinger HSS bits and step bits is confirmed independently in Lowe's product copy and in a 2021 PRNewswire release announcing the Mach-Blue line, in addition to Spyder's own site — giving it more than single-source support. The absence of any origin claim for TetraClad bits was confirmed directly on Spyder's product and collection pages. The China-origin finding for the woodboring bit set comes from a single third-party eBay reseller listing rather than a customs record or company disclosure, so it should be read as an indicator worth further confirmation rather than a settled fact. Company history and ownership (Kuhn founding, 2008 Roetheli acquisition) is corroborated across LinkedIn, LeadIQ, and RocketReach, all of which reproduce the same underlying company narrative rather than three independently reported accounts.

Production takes place at Viking's 74,000-square-foot facility at 355 State Street, St. Paul, MN — the company's sole manufacturing site, confirmed as an active industrial facility by EPA federal facility records independent of company marketing. Grinding, fluting, heat treatment, and coating of drill bits and taps are performed at this plant. The high-speed steel stock used in production is imported — Viking's own materials describe it as "globally sourced" without naming a country of origin — while the finishing and manufacturing processes that turn that steel into a finished cutting tool happen domestically at the St. Paul facility.

The St. Paul manufacturing address and facility footprint are corroborated by the EPA's Toxics Release Inventory facility database, a federal record independent of Viking's own marketing, alongside trade-directory listings from MachineTools.com and Cutting Tool Engineering magazine. The origin claim itself — "Manufactured in the USA with globally sourced materials" — is quoted directly from Viking's official site (vikingdrill.com), where it appears consistently across the homepage, product catalog, and safety data sheets, and is the basis for this entry's Assembled/Qualified label. Technical specifications (M2 steel hardness figures, NAS 907B compliance, coating types) are sourced from Viking's own catalog and are not independently confirmed by a third party. No evidence of offshore finished-product sourcing or contract manufacturing was found as of this verification date; the only confirmed offshore input is raw steel material.

All of Fuller's standard and custom tooling is designed, hand-ground, and heat-treated at the company's Warwick, RI facility. The company states its standard drill bit stock is US-made M2 high-speed steel machined to a tolerance of +0.000 to -0.005 inches; this specification comes from the company's own site and has not been independently corroborated. No evidence of offshore sourcing or imported product lines was found as of July 31, 2026 — Fuller's catalog, as listed by multiple independent woodworking retailers, is sold uniformly as US-made.

Current operating status and the Warwick, RI facility address were cross-confirmed through Dun & Bradstreet and ThomasNet business profiles, both current as of 2025–2026, and independently corroborated by the company's Yelp and Facebook business listings. Manufacturer status rests on ThomasNet's classification and its stated employee count/production activity, not solely on company marketing. Product-level "Made in USA" claims were confirmed as current (not legacy) through active listings at Hardwick & Sons, Ernie's Tools, and Tools for Working Wood. The M2 steel grade and machining tolerance figures are sourced only to the company's own site (wlfullerproducts.com, updated December 2025); no third-party technical source was found to confirm them independently. Founding year is given as an approximate decade because ThomasNet, Dun & Bradstreet, and the company's own Facebook page each state a different specific year (1941, 1943, and 1945, respectively).
