Walter 7170575 Milling Insert SDMT09T3ZDR-D57 WKP35G Carbide

Product Description

The WALTER 7170575 is a solid carbide milling insert in the SDMT square style, carrying the ANSI and ISO designation SDMT09T3ZDR-D57 in manufacturer grade WKP35G. It is a single-sided, right-hand insert with a positive rake angle of 10 degrees and a 15-degree relief angle, designed for face and shoulder milling operations. The insert features a CVD-applied TiAlN and TiN dual coating for wear resistance and thermal stability under continuous cutting loads. With 4 cutting edges and a D57 chip breaker geometry, it is sized at an inscribed circle of 0.375 inches and a thickness of 0.156 inches. Installation is performed by qualified machinists or toolroom technicians using a screw-clamping method compatible with WALTER M4000 cutter bodies.

This insert is suited for milling of steel and cast iron workpieces across P and K material grade applications. The D57 chip breaker geometry is optimized for moderate to roughing depth-of-cut conditions, with a maximum depth of cut reaching 0.375 inches (9.52 mm). It is appropriate for use in production machining environments including CNC milling centers where consistent chip control and edge life are priorities. The M4000 cutter series compatibility makes it a straightforward drop-in selection for shops already running that platform.

Key Features

• Solid carbide substrate with CVD-applied TiAlN and TiN dual coating for extended tool life in steel and cast iron
• 4 cutting edges per insert for improved cost-per-edge economy
• D57 chip breaker geometry supports controlled chip formation across a range of feed rates
• Positive rake angle (10 degrees) reduces cutting forces and heat generation
• 0.031-inch (0.80 mm) corner radius balances edge strength with surface finish capability
• Screw-on insert holding method ensures secure, repeatable seating in M4000 cutter bodies

Compatibility

Designed for use with the WALTER M4000 cutter series. Carries ANSI and ISO designations SDMT09T3ZDR-D57 WKP35G. Rated for P35 and K35 material grades, covering steel and cast iron workpiece materials.

Installation Notes

This insert is installed by a qualified machinist or toolroom technician. Power down and de-energize the machine spindle before any insert change. Use the appropriate Torx or hex key to seat and torque the clamping screw into the M4000 pocket; follow the cutter body manufacturer torque specification for the screw size used. Inspect the insert pocket seat and screw threads for debris or damage before seating a new insert.
