Tap Sets

KnKut Drill & Tap Sets take the guesswork out of threading. Every tap is matched with the exact drill bit needed to size the hole, so you never have to look up a tap-drill chart again. Available in National Coarse, National Fine, combined Coarse & Fine, and Metric thread configurations, plus spiral point tap sets for production work. The taps are made from Hi-Tungsten and Hi-Molybdenum tool steel, surface treated for lubricity with precision-ground threads; the drill bits are high-vanadium HSS, salt nitride treated to cut stainless steel and titanium without a pilot hole. Spiral point construction drives chips ahead of the tap for faster, cleaner threading in through-holes. A complete threading solution for mechanics, fabricators, and maintenance shops. USA made.
