What Are Center Drill Bits?
Center drill bits, also known as center drills, are short, rigid tools combining a pilot drill and a countersink in one body.
They are typically used to create a 60° conical starting hole that guides larger drill bits and supports lathe center operations. Center Drill Bits are widely used in precision machining industries where hole accuracy and repeatability are critical.
Materials and Coatings
For performance and durability, center drill bits are commonly made from High-Speed Steel (HSS) or cobalt steel, while carbide tips may be used in specialized cases for extra hardness and wear resistance. Coatings such as TiN and TiAlN can further improve surface hardness, reduce friction, and extend tool life.
That makes center drill bits a strong option for buyers who need consistent results across repeated drilling jobs, harder work materials, or demanding production environments.
