Walter 6158893 Milling Insert ADMT080308R-F56 WSM35S

Product Description

The WALTER 6158893 is a solid carbide indexable milling insert in the ADMT series, designed for high-performance milling in demanding materials. It carries the WSM35S manufacturer grade and features a multi-layer PVD coating of TiAlN, Al2O3, and Al for extended tool life in abrasive cutting environments. The insert has a parallelogram shape with an 85-degree included angle, a right-hand cutting orientation, and a positive rake angle of 16 degrees. With 2 cutting edges, a 0.0315-inch corner radius, and a chamfered and honed cutting edge style, this insert is suited for finishing and semi-finishing operations on difficult-to-machine workpiece materials.

This insert is intended for milling stainless steel, superalloys, and titanium - material application codes M and S - in both industrial production and job-shop environments. It is compatible with F4038 and F4042 cutter series bodies and uses a screw holding method for secure seating. The F56 chip breaker geometry supports positive cutting action and chip control in these tough materials. Installation is performed by licensed machinists or CNC tooling specialists as part of a standard insert change on compatible milling bodies.

Key Features

• Solid carbide substrate with multi-layer PVD coating: TiAlN, Al2O3, and Al for heat and wear resistance
• WSM35S grade optimized for stainless steel, superalloys, and titanium (ISO material codes M and S)
• Positive rake geometry with 16-degree rake angle and 15-degree relief angle for reduced cutting forces
• F56 chip breaker for controlled chip evacuation in gummy and work-hardening materials
• Right-hand, single-sided insert with 2 cutting edges and chamfered and honed edge preparation
• Screw-clamp holding method compatible with F4038 and F4042 cutter series bodies

Compatibility

Compatible with F4038 and F4042 WALTER cutter series bodies. ANSI and ISO code: ADMT080308R-F56 WSM35S. Catalog number: ADMT080308R-F56.

Installation Notes

Insert replacement should be performed by a qualified machinist with the spindle locked and machine power isolated. Use the appropriate Torx or hex key for the clamping screw - do not overtighten, as this can fracture the carbide substrate. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Follow the toolholder manufacturer's recommended seating and torque procedures for the applicable cutter body.
