Seco 02566008 Milling Insert APMX160408TR-M14 MK1500

Product Description

The SECO 02566008 is a solid carbide milling insert carrying manufacturer part number APMX160408TR-M14 in the APMX-16 series. It features a parallelogram shape with an 85-degree included angle, a right-hand cutting orientation, and a T-Land cutting edge style with a positive 24-degree rake angle. The MK1500 grade uses a micrograin carbide substrate with a CVD-applied TiCN and Al2O3 Duratomic coating, making it well suited to demanding cast iron face and shoulder milling operations. Machinists and CNC operators install this insert in compatible screw-retained toolholders wherever consistent edge life on ferrous materials is required.

This insert is intended for milling cast iron workpieces, corresponding to ISO material group K. It is a single-sided insert with 2 cutting edges and is held in place by a screw. Typical applications include face milling, shoulder milling, and high-feed operations on cast iron components in both production shop and job-shop environments. The 0.622-inch maximum depth of cut and 0.669-inch cutting edge effective length make it suitable for moderate to heavy stock removal passes. Compatible cutter series include R217.69-16 and R220.69-16 as stated by the manufacturer.

Key Features

• MK1500 micrograin solid carbide grade with CVD TiCN and Al2O3 Duratomic coating for extended tool life on cast iron
• Parallelogram insert shape with 85-degree included angle and positive 24-degree rake for reduced cutting forces
• T-Land cutting edge style provides a reinforced edge geometry suited to interrupted cuts and abrasive materials
• M14 chip breaker geometry controls chip formation across a range of cast iron feed rates
• Right-hand orientation with 2 cutting edges per insert maximizes cost-per-edge value
• Screw-held mounting with a 0.181-inch hole diameter for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use with SECO cutter series R217.69-16 and R220.69-16. Insert follows ANSI and ISO code APMX160408TR-M14 and is part of the APMX-16 series toolholder system.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified seating procedure when driving the clamping screw. Inspect the insert pocket and screw threads for wear or debris before installing a new insert to ensure proper seating and edge repeatability.
