Walter 5021967 Milling Insert APHT15T3PDR-K88 WXN15

Product Description

The WALTER 5021967 is a solid carbide milling insert designed for high-performance metal cutting in professional machining environments. Manufactured to ANSI and ISO standards under the APHT series, this insert carries the WXN15 manufacturer grade and features a Physical Vapor Deposition (PVD) TiCN coating for wear resistance and extended tool life. The parallelogram insert shape, 85-degree included angle, and positive 25-degree rake angle work together to reduce cutting forces. With a chip breaker designation of K88 and a sharp cutting edge style, this insert is suited for machinists and tooling professionals running milling operations on non-ferrous workpieces.

This insert is intended for milling applications involving non-ferrous metals such as aluminum and copper alloys. The right-hand cutting orientation and single-sided configuration make it a direct drop-in for compatible APHT-style toolholders. With two cutting edges per insert and a positive rake geometry, it delivers clean chip evacuation and reduced heat buildup in demanding production environments. Screw-style insert holding keeps it securely seated in the cutter body during operation.

Key Features

• Solid carbide substrate with PVD TiCN coating for wear resistance on non-ferrous materials
• Positive rake angle of 25 degrees reduces cutting forces and improves chip flow
• K88 chip breaker geometry optimized for non-ferrous metal machining
• Sharp cutting edge style for clean, burr-free cuts on aluminum and similar alloys
• Right-hand cut, single-sided insert with screw holding method for secure seating
• Conforms to both ANSI and ISO standards for broad toolholder compatibility

Compatibility

Designed as an OEM-style replacement for APHT series milling toolholders that accept the APHT15T3PDR-K88 insert style in right-hand, screw-clamp configurations.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling spindle is fully powered down and locked out before seating or removing inserts. Use the correct torx or hex key to tighten the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket for chips or debris before seating to ensure full, flat contact and accurate positioning.
