Step Drill
- Secure thin sheet metal tightly. Punch a small pilot indent first.
- Start at low speed, use the smallest step first. Keep drill perpendicular to surface.
- Use cutting fluid for metal drilling. Stop drilling once the target step fully penetrates material.
- Clear chips after each step. Do not apply heavy pressure, or the bit may overheat and break.
- Best for thin sheet metal, enlarging existing holes; NOT recommended for thick solid steel.
