About KnKut Drill Bits & Cutting Tools

KnKut is an American-made cutting tool brand with roots going back to 1980, when founder R.W. Thompson began building what would become one of the most trusted names in automotive and industrial drilling. Based in Loganville, Georgia, the company operates under R.W. Thompson, Inc. and has grown from a one-man operation into a nationally distributed supplier — all while keeping manufacturing firmly on U.S. soil. Since 1996, the KnKut line has been purpose-built for the automotive aftermarket, earning a loyal following among professional mechanics and serious DIYers alike.

What Sets KnKut Apart

The secret to KnKut's performance lies in its material science and manufacturing precision. KnKut drill bits are produced from a premium-grade Molybdenum High-Speed Steel (HSS) with a high Vanadium content — a combination that delivers exceptional hardness and toughness under demanding conditions. Each bit then undergoes a salt nitride treatment that penetrates the surface of the tool itself, rather than simply coating it, resulting in a drill that can punch through notoriously difficult materials like stainless steel and titanium alloy with reduced cycle times and more holes per bit.

This same uncompromising approach carries through to the brand's popular drill bit sets, which combine the premium steel formulation with precision-ground geometry and consistent nitride treatment across every piece in the kit. Whether you need a compact fractional set for everyday shop tasks or a comprehensive Drill Bit Buddy set spanning 1/16" to 1/2" by 64ths, KnKut offers configurations for virtually every automotive and industrial application. The precision-ground point, flutes, body clearance, and drill diameter are engineered to work together for maximum accuracy.

Beyond the Drill: Screw Extractors and More

Broken bolts and stripped fasteners are an unavoidable reality in automotive work, and KnKut addresses this with its line of screw extractors. KnKut's square-style extractors are designed to remove broken bolts and screws with minimal deformation to the surrounding material — they grip firmly without chewing up or expanding the broken part. For even more versatility, KnKut also offers combination sets that pair left-hand drill bits with square extractors, giving technicians a two-pronged approach to stubborn fastener removal in a single kit.

American-Made From Raw Material to Finished Tool

One of KnKut's most meaningful differentiators is complete domestic manufacturing. By controlling the entire production process — from raw steel selection through finished product — the brand maintains a level of quality consistency that imported tools rarely match. KnKut products are nationally distributed through automotive tool and equipment channels, making them accessible to shops and enthusiasts across the country. The brand operates under the motto "The Hole Solution," a fitting description for a company that has spent decades solving the drilling and fastener challenges professionals face every day.
