Walter 5886270 Milling Insert ADMT120416R-F56 WKP35S Carbide

Product Description

The WALTER 5886270 is a solid carbide milling insert in the ADMT series, identified by the ANSI/ISO code ADMT120416R-F56 WKP35S. It features a parallelogram shape with an 85-degree included angle, a positive rake angle of 16 degrees, and a 15-degree relief angle. The CVD-applied multilayer coating - TiCN / Al2O3 / TiCN - in manufacturer grade WKP35S is engineered for cutting steel and cast iron. Two cutting edges are available per insert, and the right-hand orientation suits standard climb and conventional milling setups. CNC machinists and tool-and-die professionals install this insert in compatible face and shoulder milling cutters.

This insert is suited for roughing and semi-finishing operations in steel and cast iron workpieces, covering material grades P35 and K35. The F56 chip breaker geometry controls chip flow at moderate-to-aggressive depths of cut, making it a practical choice for production milling on CNC machining centers in both job-shop and high-volume manufacturing environments. It is compatible with the F2010, F2252, F4042, and F4138 cutter series from WALTER. The screw-clamp holding method provides repeatable seating and fast indexing during insert changes.

Key Features

• ADMT parallelogram insert shape with 85-degree included angle and positive 16-degree rake for efficient chip formation
• CVD multilayer coating (TiCN / Al2O3 / TiCN) in WKP35S grade for wear resistance in steel and cast iron
• F56 chip breaker geometry for controlled chip evacuation at depths of cut up to 0.535 inches
• Right-hand cutting orientation with chamfered and honed cutting edge style for edge stability
• Two indexable cutting edges per insert to extend tool life per unit cost
• Screw-clamp holding method for secure, repeatable insert seating

Compatibility

Compatible with WALTER cutter series F2010, F2252, F4042, and F4138. Designed for right-hand milling operations on steel and cast iron workpieces conforming to material grades P35 and K35 per ANSI and ISO standards.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the milling spindle is powered down and locked out before indexing or replacing inserts. Use the appropriate Torx or hex key specified by the cutter body manufacturer when tightening the clamping screw - do not over-tighten, as this can damage the insert seat. Inspect the insert pocket and seating surfaces for chips or debris before securing the new insert.
