Self-Drilling Screw Troubleshooting Guide
Split at point (web) | Excessive force (feed) applied while drilling | Reduce application force |
Outer corners worn or melted | Drill RPM (cutting speed) too high | Use slower motor or partial trigger pull |
Cutting edges chipping or breaking | Excessive force (feed) applied while drilling | Reduce application force |
Point melted or diameter significantly reduced | Work material too hard | Confirm work material specs |
Insufficient chip clearance | ||
Excessive force (feed) applied while drilling | Choose screw with longer pilot section | |
Reduce application force | ||
Screw spins without drilling a hole | Drill motor set on reverse | Check motor direction |
Work material too hard | Confirm work material specs | |
Drill point blunted by handling | Inspect unused drill points for possible damage (from handling) |
