Walter 5918284 Milling Insert LPMT150412R-D51 WKP35S

Product Description

The WALTER 5918284 is a solid carbide milling insert in the LPMT series, manufactured to ANSI and ISO standards under grade designation LPMT150412R-D51 WKP35S. This right-hand, single-sided insert features a positive rake angle of 10 degrees, a honed cutting edge, and two cutting edges per insert. The CVD-applied multilayer coating - TiCN / Al2O3 / TiCN - delivers thermal resistance and wear durability suited to interrupted and continuous milling passes. The WKP35S grade targets steel and cast iron workpieces. Primary installation is performed by licensed machinists and CNC tooling technicians in production and job-shop environments.

This insert is designed for milling applications in steel and cast iron, covering both P35 and K35 material grades. The D51 chip breaker geometry controls chip formation during face milling and shoulder milling operations. The screw-holding method provides positive clamping and repeatable seating in compatible LPMT-series toolholders. It is suited to residential and commercial machine shop production work, including roughing and semi-finishing passes where reliable chip control and edge life are priorities.

Key Features

• Solid carbide substrate with CVD multilayer TiCN / Al2O3 / TiCN coating for extended tool life in steel and cast iron
• WKP35S manufacturer grade rated for P35 and K35 material application codes
• Positive rake angle (10 degrees) with honed cutting edge style reduces cutting forces
• D51 chip breaker geometry for controlled chip evacuation in milling operations
• Right-hand insert orientation with screw-holding method for positive, repeatable clamping
• Two cutting edges per insert; single-sided design for consistent geometry on each edge

Compatibility

Designed for use in LPMT-series milling toolholders that accept LPMT150412 inserts with screw-clamping. Compatible toolholders must support a right-hand insert orientation. ANSI code LPMT150412R-D51 WKP35S and ISO code LPMT150412R-D51 WKP35S are both applicable for toolholder cross-reference.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the manufacturer-specified torx or hex key for the clamping screw - do not overtighten, as this can fracture the carbide body. Confirm insert seating and clamp screw torque before resuming cutting operations.
