Efficiently install threaded fasteners in a workpiece with the tools in these tap and drill sets. They include multiple drills and taps in corresponding sizes that can be used together to create threaded holes. If you need your fasteners to install flush with the workpiece, choose a set that includes countersinks.
Drill & Tap Sets
These sets contain multiple drill bits and taps that can be used together to drill and tap holes for a precise fit when inserting a threaded fastener such as a screw or bolt into the hole. Use a drill bit to create the hole, and then use a tap in a corresponding size to create internal threads inside the hole.

Drill, Tap, & Countersink Combination Sets
Containing multiple drills, taps, and countersinks in a range of sizes, these sets provide everything you need to drill, tap, and countersink holes for a precise fit when installing fasteners. Drill bits create a hole in a workpiece, taps cut internal threads into a hole so that fasteners with corresponding external threads can be installed, and countersinks form a tapered opening at the top of the hole that lets the fastener sit flush with the surface of the workpiece.
