1. Lathe Drilling

2. Facing

3. Tool Holding

4. Center drilling

5. Providing starter for drill Critical that operator allows center drill to center Once centered, drill with moderate pressure

6. Hole Drilling For accuracy, examine drill tip Drill in multiple steps Dont force tool into part – let it cut metal, not extrude it

7. Counter Sink Let tool dwell in cut before retracting. Use correct angle depending on purpose. (60 deg. Threads. 82 deg. Screw heads. 90 deg. Chamfers)

8. Drilling Holes Drill in steps not single operation Peck don't plunge Maintain pressure don’t ram tool into work If possible use oil or coolant

9. Small hole drilling with a micro chuck Small hole drilling requires “feel”

10. Different Style Drills 150 degree point. Good for hader and abasive metals. Less deflection. Extra cutting edge. Coolant through design Flat drill has no rake. Produces small chips. Doesnt grab in soft metal

11. Todays lathe operation Face part Center drill Drill pilot Drill to size Chamfer Inspect with gauge pins
