Hex Shank Drill Taps for Drills and Screwdrivers
 |
With a drill bit point to drive into the workpiece, these taps can drill and tap holes in a single step. A 1/4" hex shank connects them directly to tools such as drills and power screwdrivers. They're made of high-speed steel and are for use on most metal and plastic.
Their spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.
Uncoated High-Speed Steel—Uncoated taps are strong enough for most tapping jobs but have the shortest tool life.
Titanium Nitride (TiN)-Coated High-Speed Steel—Titanium Nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.
