Frequently Asked Questions
What is the advantage of the black oxide finish on these drill bits?
The black oxide coating provides increased abrasion resistance, reduces drilling friction, and offers mild corrosion resistance, effectively extending the operational life of the high-speed steel.
What materials are suitable for a 118° point angle?
A standard 118° point angle is the industry norm for general-purpose drilling in softer materials, including mild steel, aluminum, wood, and plastics.
