Kyocera TMC08662 WNMG432KG CA310 Turning Insert Carbide

Product Description

The KYOCERA TMC08662 is a solid carbide turning insert in the WNMG432KG geometry, manufactured to ANSI and ISO standards under the CA310 grade. It carries a CVD-applied multilayer coating of TiCN and Al2O3 for thermal resistance and wear performance during continuous and interrupted cuts. The insert features an 80-degree trigon shape with a neutral hand orientation, a 0.5-inch inscribed circle, and a 1/32-inch corner radius (0.0313 inches). The KG chip breaker geometry and chamfered-and-honed cutting edge style are optimized for cast iron machining. Machinists and CNC operators working in production turning environments install this insert in compatible toolholders for external turning, boring, facing, internal facing, and chamfering operations.

This insert is intended primarily for cast iron workpiece materials, corresponding to ISO material grade classifications K01, K10, and K20. It fits applications in both roughing and finishing passes where a negative-rake, 80-degree trigon geometry is specified. With six cutting edges per insert and compatibility with both clamp and pin holding methods, it suits high-volume production cells running cast iron components. The CA310 grade is part of KYOCERA Series CA3, designed for general-purpose cast iron turning with CVD-coated carbide substrates.

Key Features

• CVD multilayer coating: TiCN and Al2O3 for thermal and abrasion resistance in cast iron cutting
• Six cutting edges per insert for extended tool life per unit
• KG chip breaker geometry with chamfered-and-honed edge for controlled chip formation
• Neutral hand orientation for flexible toolholder mounting
• Compatible with clamp and pin insert holding methods
• Negative rake angle (-14 degrees) suited to hard, abrasive cast iron grades

Compatibility

Designed for use with WNMG-style toolholders accepting an 80-degree trigon insert with a 0.5-inch inscribed circle, 3/16-inch insert thickness, and a hole diameter of approximately 0.2032 inches. ISO code reference: WNMG080408KG. Industry standard number: WNMG432KGCA310. Suitable for external turning, boring, facing, internal facing, and chamfering operations on cast iron workpieces per the input application data.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Before changing inserts, the machine spindle must be fully stopped and locked out per shop lockout/tagout procedures. Seat the insert fully against the toolholder pocket before engaging the clamp or pin to avoid micro-movement under cutting load. Inspect the pocket and clamp for wear or debris before installing a new edge, as pocket damage directly affects insert seating and dimensional accuracy.
