What is a key drill bit safety rule?

• A. Wear eye protection at all times
• B. Use dull bits for hard materials
• C. Keep it sharpened
• D. Run at high speed

Answer: (C)

Keeping drill bits sharp is the key safety habit because a sharp bit cuts cleanly instead of skidding or rubbing. When the bit bites well, it requires less downward force, stays in control, and produces less heat. This reduces the chance the bit will bind, grab the material, or break, which are common causes of slips and injuries. A dull bit, by contrast, fights the material, increases friction and heat, and is more prone to wandering or kicking back. The other options touch on safety in general, but they don’t address the main risk tied to the bit’s condition. So maintaining a sharp drill bit is the safest, most fundamental rule.
