Key Advantages

Superhard & Wear-Resistant: PCD hardness is 10x that of carbide, with minimal wear when machining high-silicon aluminum/CFRP, reducing tool change frequency by 70%+

Zero Rake Angle Precision: Zero rake angle design improves workpiece extrusion finish, achieving mirror-grade surface quality without burrs or vibration marks

3-Edge High Efficiency: 3-edge tip structure suitable for high-volume automated production, increasing efficiency by 2-3x

Stable Chip Evacuation: Rake face chip breaker groove ensures smooth chip removal, preventing chip winding and workpiece scratches

High Thermal Stability: Fast heat dissipation, high temperature resistance, no deformation during high-speed cutting, and long-lasting dimensional accuracy

1.Diamond cutting inserts with zero-degree rake angles provide superior material extrusion characteristics, resulting in workpieces with exceptional extrusion finish quality.

2.T-type CBN inserts with three-edged tips are optimized for high-volume production. Featuring back angles and coatable edges, these tools deliver extended tool life and reduced wear—ideal for large-scale manufacturing efficiency；
