Kennametal 2877456 Milling Insert EDPT180512PDERHD KC725M

Product Description

The KENNAMETAL 2877456 is a solid carbide milling insert carrying ISO designation EDPT180512PDERHD and ANSI code EP1812EHD. It features a parallelogram shape with a positive rake geometry and a 15-degree relief angle, making it well suited for high-productivity face and shoulder milling operations. The insert is coated with TiAlN via a PVD process, delivering heat and wear resistance in demanding cutting environments. Key physical dimensions include an inscribed circle of 0.428 inches, a thickness of 0.217 inches, and a length of 0.857 inches. A 3/64-inch (0.047 inches) corner radius provides edge strength while maintaining surface finish quality. This insert is intended for installation by machinists and tooling specialists on CNC milling platforms.

This insert is designed for cutting steel, stainless steel, superalloys, and titanium — material application codes P, M, and S. It carries the HD chip breaker designation, which is optimized for heavier chip loads and interrupted cuts common in production milling of ferrous and high-temperature alloys. The right-hand orientation and single-sided design mean it is indexed once per edge, with two cutting edges available per insert. It is compatible with the Kennametal Mill 1-18 cutter series as noted by the manufacturer.

Key Features

• TiAlN PVD coating for extended tool life in steel, stainless steel, superalloys, and titanium
• Positive rake geometry with 15-degree relief angle reduces cutting forces
• HD chip breaker optimized for heavier feeds and interrupted cuts
• Two cutting edges per single-sided insert maximize cost efficiency per unit
• Honed cutting edge style promotes edge stability and reduces micro-chipping
• Screw-held mounting method ensures secure, repeatable seating in the cutter body

Compatibility

Compatible with the Kennametal Mill 1-18 cutter series. ISO designation EDPT180512PDERHD and ANSI code EP1812EHD conform to ANSI and ISO standards for interchangeability reference. Insert size code is 1812.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The machine spindle must be fully stopped and locked out before inserting or indexing any cutting insert. Use the appropriate torx or hex key to the cutter body screw to the manufacturer-specified procedure — do not overtighten, as this can crack the carbide insert. Inspect the insert pocket and seating surface for chips or debris before seating the insert to ensure proper contact and runout accuracy.
