Tap & Drill Bit Sets

KnKut Tap and Drill Bit Sets take the guesswork out of threading. Each set pairs a USA-made spiral point tap with the correctly-sized drill bit, so you always start with the right pilot hole, no tap drill chart required. Everything is matched and ready to use straight out of the box. The taps are built from high-speed steel with a spiral point design that pushes chips forward ahead of the cut, keeping the flutes clear and the thread clean. That makes them the right choice for through-hole production tapping in steel, stainless, and other hard metals where chip buildup is a problem.

Available in National Coarse and National Fine thread sets. Built for auto mechanics, fabricators, and industrial maintenance shops that need a reliable threading solution without hunting for matching components. USA-made.
