Countersink Chipping? Causes and Solutions
Expert analysis of Countersink chipping causes with Lihao Technology exclusive solutions
🔍 Cause Analysis of Countersink chipping
1. Brittle Tool Material
Standard carbide is too brittle - edges chip on hard spots or impact
2. Edges Too Sharp
Tiny edge angles concentrate stress and chip during cutting
3. Improper Cutting Parameters
Feed or depth too high exceeds tool strength, causing chipping
4. Hard Spots in Material
Hard points or inclusions in the workpiece impact and chip the tool
5. Improper Tool Mounting
Loose or eccentric clamping loads the tool unevenly, causing chipping
