💡 What is a center drill bit used for in metalworking and lathe setups?
Center drilling creates a precise guide hole and countersink for accurate hole starting, helping to reduce drift and improve hole quality in metalworking.
- Center drilling establishes a starting point for subsequent drilling on lathe work - Improves alignment for alloys like steel, cast iron, and stainless - Reduces wandering and chatter, extending tool life
