Once we have drilled the initial hole, we then need a tapping bit. We can use a Bottoming Tap, a Plug Tap or a Taper Tap.
For our use, we prefer a Taper Tap Bit 5/16 Inch #18. These taps narrow a bit at the tip, therefore they can be inserted easier into the hole we drilled earlier.
Each unit comes with:
- 1 x 5/16" - 18 HSS Tap Bit
