Hex Shank Combination Drill Bits/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 taps are strong enough for most tapping jobs but have the shortest tool life.

Combination Drill Bit/Taps

Drill holes and cut threads without switching tools. Made of high-speed steel, these taps are for use on most metal and plastic. The square shank is compatible with tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.
Taps with spiral flutes keep chips clear by drawing them back toward the tap and out of the hole.
Uncoated taps are strong enough for most tapping jobs but have a shorter tool life.
