KnKut Drill Bit Set

KnKut Drill Bit Sets: American-Made Precision for Tough Jobs

When a drilling task demands accuracy, longevity, and the ability to cut through unforgiving materials, KnKut drill bit sets stand out as a trusted choice among automotive professionals and serious DIYers alike. Born from R.W. Thompson, Inc.'s commitment to American craftsmanship, KnKut drill bit sets are engineered from the ground up to outperform the competition — not just in initial sharpness, but in sustained cutting performance over hundreds of holes.

What Sets KnKut Drill Bit Sets Apart

At the core of every KnKut set is a carefully selected material: high-grade Molybdenum High Speed Steel (HSS) with a high Vanadium content. This alloy combination gives the bits the base hardness necessary to drill demanding materials like stainless steel and titanium alloy. But KnKut goes a step further — their drill bits undergo a salt nitride treatment that actually penetrates the tool's surface, rather than simply coating it, delivering hardness that doesn't chip or peel away under heat and friction.

Every bit in a KnKut set also features a 135° split point tip, which starts drilling on contact and self-centers without requiring a center punch or pilot hole. Combined with precision-ground flutes, body clearance, and drill diameter, these sets deliver rounder, more accurate holes and a lower cost-per-hole than budget alternatives.

A Set for Every Application

KnKut's drill bit set lineup covers a wide range of professional scenarios:

• Jobber Length Sets – The classic all-around workhorse, available in 21-piece and 29-piece configurations spanning 1/16" through 1/2" by 64ths. The flagship Drill Buddy set packages 29 bits in a high-impact plastic clip-on caddy that hooks to a tool belt, bucket, or ladder for fast bit access on the job site.
• Mechanics Length Step Point Sets – These sets combine a split-tip step design with a shorter, sturdier mechanics-length shank. Available in 13-, 15-, and 29-piece configurations, they start on contact, reduce heat buildup to extend tool life, and can even enlarge existing holes without damaging the bit point. Sizes 3/16" and above feature 3-flats on the shank to eliminate chuck slippage.
• Short Stubby Length Sets – Engineered for confined spaces and right-angle drills, the shorter flute and overall length produce a more rigid bit that resists deflection and breakage — critical in tight automotive repair scenarios.
• M35 Cobalt Sets – For the most demanding heat-intensive applications, KnKut's Cobalt bits resist heat to stay sharper longer, making them ideal for hard metals and repetitive industrial drilling.
• Left Hand Sets – Purpose-built for broken bolt extraction, left-hand spiral bits often remove damaged fasteners as they drill, saving hours of frustrating manual work.

Made in the USA, Built for Professional Demands

Unlike many competing brands that source overseas, KnKut manufactures all drill bits and cutting tools domestically, maintaining quality control from raw steel to finished product. This end-to-end oversight is a key reason KnKut drill bit sets consistently reduce drilling cycles and maximize the number of holes per bit — a genuine value proposition for shops and mechanics who drill day in and day out.
