Premium Hex Shank Hand Tap Drill Bit Set combination bits for drilling, tapping, and countersinking - all with one bit.

Tap Drill Bit combination bits are a high-quality solution when you need to drill, tap, and countersink a hole quickly and accurately.

Previously to create a threaded hole you would have to perform three separate operations, each requiring its own tool: a drill bit, a tap, and a countersink tool.

The Tap Drill Bit combination bits perform all three operations with one bit, providing you with the same accuracy and power in a simple, fast, and easy-to-use package. A quick change adapter is also included to help you to drill, tap, and countersink, and even drive fasteners even faster.

For use with up to 10-gauge mild steel, the Tap Drill Bit combination bits make drilling, tapping, and countersinking holes faster and easier than ever before.

Highlights:

• Drill, tap and countersink in one quick and easy action
• Just as precise and considerably faster than using standard bits, tapping, and countersinking tools
• Hardened high-grade tool steel construction for use in up to 10-gauge metal
• Back-tapered to avoid damage from over drilling
