Performance Advantages

✅ Enhanced Chip Control - Specialized chipbreaker prevents chip packing in deep holes

✅ Superior Surface Quality - Achieve Ra 0.6μm internal thread surfaces consistently

✅ Extended Tool Life - Optimized geometry reduces cutting forces by 25%

✅ Versatile Application - One insert covers multiple pitch requirements

✅ Reduced Machine Time - High cutting speeds increase productivity

Troubleshooting Common Issues

 

Problem	Cause	Solution
Poor thread finish	Excessive speed	Reduce by 15-20%
Chip packing	Insufficient coolant	Increase pressure/volume
Insert breakage	Feed too high	Reduce feed rate
Rapid wear	Wrong grade	Select appropriate grade
Thread tearing	Dull edge	Index to fresh cutting edge
