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.

Hex Shank Taps for Drills and Screwdrivers

All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
