💡 What is an annular cutter and why use it instead of a twist drill?
Annular cutters only cut the rim of the hole, so they work faster with less power.
- They leave a solid slug instead of turning it all to chips.
- Cuts are cleaner and more accurate than twist drills in steel.
- They run great on magnetic drills for big holes.
