Walter 7499353 Turning Insert CCGT09T302-FM2 WSM01

Product Description

The WALTER 7499353 is a coated carbide turning insert designed for precision metal cutting in demanding machining applications. Identified by ISO code CCGT09T302-FM2 WSM01, this insert features an 80-degree diamond shape with a positive rake geometry and a 0.008 inch (1/128 inch) corner radius. The TiAlN coating is applied via PVD process under the proprietary WSM01 grade designation, delivering heat resistance and edge durability. The FM2 chip breaker geometry controls chip flow during finishing and semi-finishing passes. Licensed HVAC and machining trades rely on this insert for consistent surface finish and dimensional accuracy on difficult-to-machine materials.

This insert is engineered primarily for stainless steel, superalloys, and titanium workpieces, placing it in ISO material groups M and S. It also performs on steel, non-ferrous metals, and hard materials (ISO groups P, N, and H). Suitable applications include turning, facing, and boring operations on CNC lathes and machining centers in both production and job-shop environments. The screw-holding method and neutral hand orientation make it compatible with a wide range of standard toolholders accepting CCGT-style inserts.

Key Features

• TiAlN PVD coating under WSM01 grade for extended tool life on stainless steel and superalloys
• 80-degree diamond insert shape with positive 18-degree rake angle reduces cutting forces
• FM2 chip breaker designed for finishing and light semi-finishing passes
• 0.008 inch corner radius for tight-tolerance finishing work
• Maximum depth of cut 0.079 inch (2.00 mm) for controlled material removal
• Two cutting edges per insert; screw-held, neutral hand
• Multi-use geometry supports turning, facing, and boring in a single insert

Compatibility

Designed for use in CCGT-style screw-clamp toolholders accepting a 3/8 inch inscribed circle insert. Compatible with ISO material groups M (stainless steel), S (superalloys and titanium), P (steel), N (non-ferrous metals), and H (hard materials). Material grades M10, S10, P10, N10, and H20 apply per the manufacturer specification. Conforms to ANSI and ISO standards; industry standard number CCGT3(2.5)0.5-FM2 WSM01.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully and flat in the pocket before tightening the clamping screw to avoid chipping the cutting edge. Inspect the insert seat and toolholder pocket for debris or damage before each insert change.
