Troubleshooting for Insert Damage 4. Crater wear
Examples of trouble with the cutting edge

1. Chipping, fracture

2. Flaking

5. Initial chipping

3. Flank wear

Problem Cause Grade Solution
1. Chipping, fracture • Use a tough grade Cutting conditions / other
• Excessive vibration
2. Flaking or impact • Use a tough grade • Reduce the feed rate
3. Flank wear • Eliminate the vibration
• Torn away built-up edge • Use a grade with high
4. Crater wear • Excessive vibration wear resistance • Reduce the feed rate
• Eliminate the vibration
5. Initial chipping or impact • Use a coated grade • Reduce the cutting speed
• Cutting speed too high • Use a grade with high • Reduce the feed rate
• Inadequate tool toughness • Use coolant properly
wear resistance • Reduce the cutting speed
• Cutting speed too high • Use a coated grade • Reduce the feed rate
• Feed rate too high • Use a tough grade • Use coolant properly
• Inadequate tool toughness • Adjust or change the guide
• Inappropriate guide
bushing or pilot hole
bush or pilot hole • Reduce the feed rate
• Misalignment • Correct the misalignment
