Countersink Life Too Short? Causes and Solutions
Expert analysis of Short countersink life causes with Lihao Technology exclusive solutions
🔍 Cause Analysis of Short countersink life
1. Low Tool Hardness
Standard HSS below HRC62 wears fast on hard materials like stainless steel
2. Poor Tool Coating
Low-hardness, low-heat-resistance coatings wear off quickly
3. Improper Cutting Parameters
High speed or feed raises temperature and accelerates wear
4. Poor Edge Grinding Quality
Rough grinding leaves micro-nicks that wear quickly
5. Hard Spots in Workpiece
Hard points or inclusions accelerate tool wear
✅ Lihao Technology Solutions
Cobalt HSS HRC67
5 degrees harder than standard HSS - 3x wear resistance, long life on stainless steel
TiAlN Composite Coating
HV3000 hardness, heat-resistant to 1100 degrees C - coating stays intact, protecting edges
Swiss Precision Grinding
ANCA-ground edges without micro-nicks - even wear, longer life
Optimized Cutting Parameters
Best parameters per material prevent overheating and fast wear
