Kennametal 1112600 Milling Insert APKT1604PDR KC725M Carbide

Product Description

The KENNAMETAL 1112600 is a solid carbide milling insert in the APKT series, designed for indexable face and shoulder milling operations on steel, stainless steel, and superalloy workpieces. It carries the KC725M manufacturer grade and features a PVD-applied TiN/TiCN/TiN multilayer coating that extends edge life under moderate to aggressive cutting conditions. The insert uses a parallelogram shape (APKT style) with an 85-degree included angle, an 11-degree relief angle, and a 0.0315-inch corner radius. Screw-type holding locks the insert securely in the pocket. Licensed HVAC and machining trade professionals installing these in production tooling will recognize this geometry as a standard high-performance finishing and semi-finishing option.

This insert is sized for applications in metalworking where controlled chip formation and edge stability across steel, stainless steel, and superalloys including titanium are required. With a maximum depth of cut of 0.4330 inches and an inscribed circle of 0.4330 inches, it suits both light finishing passes and moderate material removal rates. The right-hand cutting configuration makes it compatible with standard right-hand milling cutter bodies accepting APKT-style pockets. Material grade designations C5, C6, and C7 indicate suitability across a broad hardness range in the ferrous and superalloy categories.

Key Features

• Solid carbide substrate with PVD TiN/TiCN/TiN multilayer coating for extended tool life
• KC725M grade engineered for steel, stainless steel, and superalloys including titanium
• APKT parallelogram geometry with 85-degree included angle and 11-degree relief angle
• 0.0315-inch (0.80 mm) corner radius for controlled edge strength and surface finish
• Screw-type insert holding method for repeatable, rigid pocket seating
• Right-hand cutting configuration; ISO code APKT1604PDR

Compatibility

Designed for use in right-hand APKT-style indexable milling cutter bodies accepting size 26 inserts with screw-type clamping. ISO code APKT1604PDR identifies direct pocket compatibility. Verify cutter body seat geometry and screw size before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine locked out per standard lockout/tagout procedure. Use the correct torque wrench and manufacturer-specified clamping screw for the cutter body to avoid seat damage or insert fracture. Inspect the pocket seat and clamping screw for wear or debris before seating a new insert. Index or replace all inserts in a multi-insert cutter body at the same time to maintain balanced cutting forces.
