Hex-Shank Combination Drill Bit/Tap Sets for Drills and Screwdrivers

Drill and tap holes in a range of diameters. With a drill bit point to drive into the workpiece, these tools can drill and tap holes in a single step. Connect them directly to 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. Their spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. Recommended for use in through holes, all have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.
Titanium nitride (TiN) coated taps last longer and can drill at higher speeds than uncoated taps.

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.

Uncoated taps are strong enough for most tapping jobs but have the shortest tool life. Titanium Nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.
