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) |
