MATERIAL
APPLICATIONS
Tool geometry, substrate grade, and coating are selected based on the specific material being machined. Each application has different requirements.
Stainless Steel
304, 316, 17-4PH, and duplex grades. Requires sharp edges, positive rake, and heat-resistant coatings to manage work hardening and chip evacuation.
TiAlN or AlTiN coating recommended
Fine-grain carbide substrate
Polished flutes for chip flow
Alloy Steel
4140, 4340, H13, and high-speed steel grades. Demands high wear resistance and thermal stability at elevated cutting speeds and feed rates.
AlTiN coating for heat resistance
Medium-grain substrate
Honed cutting edge geometry
Cast Iron
Gray iron, ductile iron, and compacted graphite iron. Abrasive material demands high hardness substrate and specific edge preparation to reduce flank wear.
TiN or uncoated for dry cutting
High-hardness carbide grade
Negative rake for stability
Special Applications
Titanium alloys, nickel superalloys, hardened steels, and composite materials. Complex applications require customised tool geometry and substrate selection.
