Seco 02546819 Milling Insert XOEX120404FR PCD20 Carbide

Product Description

The SECO 02546819 is a solid carbide milling insert carrying the ANSI and ISO designation XOEX120404FR with a manufacturer grade of PCD20 (Polycrystalline Diamond, medium grain). It is a single-sided, right-hand parallelogram insert designed for high-precision milling of non-ferrous metals. The insert measures 0.5465 inches in length and 0.3220 inches inscribed circle diameter, with a thickness of 0.1980 inches and a 0.0157-inch corner radius. The bright, uncoated finish and sharp cutting edge style preserve edge sharpness on aluminum, copper, and similar soft, abrasive-sensitive workpiece materials. Installation is performed by licensed machinists and CNC tooling specialists using screw-held insert pockets.

This insert is suited for milling operations on non-ferrous metals in both production and job-shop environments. It operates with a positive rake angle of 15 degrees and a 15-degree relief angle, characteristics that reduce cutting forces and improve chip evacuation on soft, gummy materials. The XOEX-12 series insert belongs to the SECO XOEX120404FR family and is compatible with SECO cutter series R217.69-12 and R220.69-12. Maximum depth of cut reaches 0.1575 inches, making it appropriate for light to moderate finishing and semi-finishing passes on non-ferrous workpieces in CNC milling centers.

Key Features

• PCD20 polycrystalline diamond grade with medium grain structure for non-ferrous milling
• Positive rake angle of 15 degrees reduces cutting forces on soft, abrasive-sensitive materials
• Sharp, uncoated cutting edge preserves accuracy on aluminum, copper, and similar alloys
• Maximum depth of cut of 0.1575 inches suitable for finishing and semi-finishing passes
• Screw-held insert design ensures secure, repeatable seating in compatible cutter bodies
• Compliant with ISO and ANSI insert standards; ANSI and ISO code XOEX120404FR

Compatibility

Compatible with SECO cutter series R217.69-12 and R220.69-12 as stated by the manufacturer. Insert size code 120404 corresponds to the XOEX-12 series. Verify cutter body pocket geometry and hand orientation before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle fully before changing inserts. Use the correct torque driver for the screw-held pocket to avoid cracking the PCD substrate. Inspect the pocket seat for debris or damage before seating the insert, as contamination will affect runout and edge life on precision non-ferrous cuts.
