Description

The SECO 02566062 is a solid carbide milling insert carrying ANSI and ISO designation SEEX09T3AFTN-M08 and manufactured to grade MK1500. The insert features a square shape with a 90-degree included angle, four cutting edges, and a neutral rake and hand orientation. It is coated via CVD with a TiCN and Al2O3 Duratomic coating classification, which delivers wear resistance suited to demanding milling operations. At 0.3750 inches inscribed circle and 0.1563 inches thick, the insert is designed for rigid toolholders in production milling environments. Licensed machinists and CNC operators handling cast iron components are the primary users of this insert.

This insert is engineered for cast iron milling applications, classified under primary workpiece material code K. The M08 chip breaker geometry is optimized for the cutting forces and chip control demands typical of gray cast iron, ductile iron, and similar ferrous materials in both roughing and semi-finishing passes. The T-Land cutting edge style adds edge strength for interrupted cuts and hard spots common in cast iron workpieces. It is sold individually but requires a minimum order quantity of 10 units per order.

Key Features

Solid carbide micrograin substrate with CVD-applied TiCN and Al2O3 Duratomic coating for heat and wear resistance
Four cutting edges per insert for extended tool life and lower cost per edge
M08 chip breaker geometry optimized for cast iron milling
T-Land cutting edge style provides edge reinforcement for interrupted cuts
Neutral rake and neutral hand fits a wide range of compatible cutter bodies without handedness restrictions
Maximum depth of cut of 0.2795 inches supports both roughing and semi-finishing applications
Screw-lock insert holding method for secure seating in compatible toolholders

Compatibility

Compatible with SECO cutter series R217.53-09 and R220.53-09 as stated by the manufacturer. ANSI and ISO code SEEX09T3AFTN-M08 applies to both designations. Always verify toolholder compatibility using the manufacturer cutter series documentation before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque driver for the screw-lock fastener follow the cutter body manufacturer torque specification for the SEEX-09 series pocket screw. Inspect the pocket seating surface for chips or debris before installing a fresh insert to ensure full contact and prevent premature edge failure.
