SNMM-GZ 90° Rhombic Turning Insert for Gravity Machining with GZ Chipbreaker
SNMM-GZ is a single-sided square negative-rake cemented carbide turning insert with 4 cutting edges. Optimized with GZ heavy-duty 3D chipbreaker for gravity machining. The high-toughness substrate and wear-resistant CVD coating provide reliable chip breaking and superior impact resistance under heavy cuts.
Product Features
- Suitable for rough machining of forged and cast steel with oxide scale
- Covers carbon steel and alloy steel applications
- Four cutting edges help reduce machining costs
- Superior impact resistance under heavy cuts
