SNMG120404-HA is a square indexable tungsten carbide insert, specially designed for metal grooving, slotting and general turning operations.
The HA chipbreaker geometry delivers smooth chip flow and low cutting resistance, ideal for sheet metal grooving work.
Multi-layer hard coating improves wear resistance and extends tool life.
Key Features
Model: SNMG120404-HA
Optimized for 0.6–1mm thin stainless steel sheet V-grooving
HA chip breaker: low cutting load, prevents workpiece distortion
4 usable cutting edges for cost savings
Smooth chip evacuation, no burrs on grooved surface
Application CNC sheet metal grooving machine, stainless steel cabinet, elevator panel, decorative metal sheet V-grooving.
Precision V-Grooving for 0.6–1 mm Stainless Steel Sheets: Engineered with ultra-fine geometry and optimized cutting edge preparation to deliver ±0.05 mm groove depth accuracy and consistent 30°–90° V-angle profiles on thin stainless steel — critical for high-tolerance bending in elevator panels and cabinet fabrication.
Low-Load, Anti-Deformation Design: Features a shallow rake angle (−5°) and reinforced chipbreaker geometry to minimize radial cutting force (< 80 N at 0.3 mm depth), preventing sheet distortion and spring-back — essential for maintaining flatness in thin-gauge stainless steel (≤1 mm).
Cost-Effective 4-Edge Indexability: Full square geometry with four symmetrical, precision-ground cutting edges enables up to 4× longer tool life per insert — reducing consumable cost by ~65% versus single-edge alternatives in high-volume stainless steel V-grooving applications.
Burr-Free Surface Finish (Ra ≤ 0.4 μm): TiAlN-coated tungsten carbide substrate combined with honed cutting edge ensures smooth, burr-free groove walls — eliminating secondary deburring and enabling direct welding or polishing in premium stainless steel architectural components.
