1 17/32" Drill Bits | McMaster-Carr

Multiple tap sizes allow tapping a range of hole diameters. The taps in these sets connect directly to the included screwdriver and other tools that accept a 1/4" hex shank, such as drills and power screwdrivers. They're made of high-speed steel and are for use on most metal and plastic. With a plug chamfer, they're good for start-to-finish tapping, but they'll require space at the bottom of closed-end holes for chips to accumulate.

Hex Shank Taps for Drills and Screwdrivers

Insert these taps directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank. They're made of high-speed steel and are for use on most metal and plastic. 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.
