Seco 02566285 Milling Insert SEMX1505AFTN-M18 MK1500

Product Description

The SECO 02566285 is a solid carbide milling insert carrying ANSI and ISO designation SEMX1505AFTN-M18, manufactured to MK1500 grade with a Duratomic CVD-applied TiCN and Al2O3 coating. This single-sided, square-shaped insert features a positive rake angle of 5 degrees and a T-Land cutting edge style, providing four usable cutting edges per insert. At 0.2189 inches thick and 0.6250 inches wide, it is sized for the SEMX-15 series and is held in place by a screw-clamping method. It is installed by machinists and toolroom technicians on milling machines equipped with compatible cutter bodies.

This insert is engineered primarily for milling cast iron (ISO material code K) and is suited for use in production and job-shop environments where consistent surface finish and edge life on ferrous workpieces are required. The MK1500 micrograin carbide substrate combined with the Duratomic CVD coating supports stable cutting performance at elevated speeds typical of cast iron milling operations. The neutral hand orientation makes it adaptable to standard milling setups. Compatible cutter series is R220.53-15.

Key Features

• Solid carbide micrograin substrate with CVD-applied TiCN and Al2O3 Duratomic coating for wear resistance on cast iron
• Square insert shape with 90-degree included angle and positive 5-degree rake for efficient chip formation
• T-Land cutting edge style provides edge strength and controlled chip flow
• Four cutting edges per insert — single-sided, neutral hand orientation
• Maximum depth of cut: 0.4055 inches
• Screw-clamping insert holding method for secure, repeatable seating in compatible cutter bodies

Compatibility

Designed for use with the R220.53-15 cutter series. ANSI and ISO code SEMX1505AFTN-M18 identifies fitment within the SEMX-15 insert series at insert size code 1505.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to torque the clamping screw according to the cutter body manufacturer specifications — do not over-torque, as this can crack the carbide insert. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert.
