💡 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.
