Kennametal 2451578 Milling Insert EDCT180512PDFRLDJ KC410M

Product Description

The KENNAMETAL 2451578 is a solid carbide milling insert with a PVD-applied Titanium Diboride (TiB2) coating, designed for high-performance milling of non-ferrous metals. It follows the ISO designation EDCT180512PDFRLDJ and ANSI code EC1812FJ. The insert features a parallelogram shape with a 70-degree included angle, a positive rake geometry, and a sharp cutting edge style. With a corner radius of 0.0472 inches (3/64 inch) and a relief angle of 15 degrees, it is engineered to deliver clean, precise cuts in aluminum, copper, and similar non-ferrous workpiece materials. Sold individually, with a minimum order quantity of 5 units.

This insert is suited for use in CNC milling operations targeting non-ferrous metals in both production and job-shop environments. It is compatible with the Kennametal Mill 1-18 cutter series and is held in place via a screw-lock method. The right-hand cut orientation and LD chip breaker geometry make it appropriate for finishing and semi-finishing passes where chip control and surface finish consistency are priorities. Licensed machinists and CNC operators working in aerospace, automotive, and general manufacturing applications will find this insert a direct fit for compatible toolholders.

Key Features

• Solid carbide substrate with PVD Titanium Diboride (TiB2) coating for non-ferrous metal applications
• Positive rake angle with sharp cutting edge for reduced cutting forces on aluminum and copper alloys
• 15-degree relief angle for clearance and reduced flank wear
• LD chip breaker for effective chip evacuation during milling passes
• Right-hand insert orientation with screw-lock holding method
• 2 cutting edges per insert, single-sided design

Compatibility

Compatible with the Kennametal Mill 1-18 cutter series. Insert size code 1812 corresponds to ANSI code EC1812FJ and ISO code EDCT180512PDFRLDJ.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. The machine spindle must be fully stopped and the toolholder secured in a vise or fixture before seating or replacing the insert. Use the appropriate Torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque. Inspect the pocket seat and screw threads for wear or contamination before installing a new insert.
