What is most important for drill-bit safety?

• A. Use dull bits
• B. Keep it sharpened
• C. Keep it warm
• D. Keep it clean

Answer: (B)

Keeping drill bits sharp is essential for safety. A sharp bit cuts cleanly with minimal resistance, giving you better control and reducing the chance the bit will grab, wander, or twist in your hand. Dull bits require more force, create more heat, and are more prone to binding or breaking, which can cause sudden slips or injuries and damage to the material. While being well-maintained—clean and properly stored—helps overall, sharpness directly minimizes the biggest safety risks you face when drilling. Regularly sharpen or replace dull bits to maintain safe, predictable drilling.
