- Combination Drill and Tap Bit Set Hex Shank Spiral Flute Tapping
- Each one is a combination of a twist drill bit and a tap.
- The point is the same as a twist drill bit, which is self-centering.So you don't have to buy a centering drill bit or a center punch.
- Now you can drill and tap at the same time in one operation. Just drill until the drill section fully enters the material, then the tapping will start to occur.
