Kennametal 5545403 Milling Insert KCPM40 Solid Carbide

Product Description

The KENNAMETAL 5545403 is a solid carbide milling insert with ISO designation EDPT180516PDSRGD and manufacturer grade KCPM40. It features a dual-layer PVD coating — TiAlN and AlCrN — engineered for cutting steel, stainless steel, superalloys, and titanium. The insert has a parallelogram shape with a 70-degree included angle, a positive rake angle of 15 degrees, and a chamfered and honed cutting edge style. Thickness is 0.2165 inches and inscribed circle diameter is 0.429 inches. With two cutting edges and a right-hand orientation, this insert is used in high-demand milling operations where coating durability and edge integrity are critical. It is installed using a screw-holding method.

This insert is suited for milling applications in both production and job-shop environments where the primary workpiece materials are steel (ISO P), stainless steel (ISO M), superalloys, and titanium (ISO S). The GD chip breaker geometry supports positive-rake cutting, helping manage chip formation in these demanding material groups. It is compatible with the Kennametal Mill 1-18 cutter series. The ANSI code for this insert is EP1816S and the ISO code is EDPT180516PDSRGD. It is a single-sided insert sold individually with a minimum order quantity of 5 pieces.

Key Features

• PVD-coated with TiAlN and AlCrN layers for heat and wear resistance in steel and superalloy cutting
• KCPM40 grade solid carbide substrate engineered for interrupted and continuous milling cuts
• Positive rake angle of 15 degrees with chamfered and honed cutting edge for controlled engagement
• GD chip breaker geometry supports effective chip control in ISO P, M, and S material groups
• Two cutting edges per insert, right-hand orientation, screw-clamped seating
• Meets ANSI and ISO dimensional standards — ANSI EP1816S, ISO EDPT180516PDSRGD

Compatibility

Designed for use with the Kennametal Mill 1-18 cutter series. Insert size code is 1816. Suitable for milling steel, stainless steel, superalloys, and titanium workpiece materials per ISO material group designations P, M, and S.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Secure the insert using the designated clamping screw — verify the seating pocket is clean and free of chips before placement. Power down and lock out the machine spindle before any insert change. Do not exceed the cutter body's rated speed or feed recommendations for the insert geometry in use.
