Seco 10001026 Milling Insert XOMX160508TR-MD14 MK2050

Product Description

The SECO 10001026 is a solid carbide milling insert carrying ANSI and ISO designation XOMX160508TR-MD14 and manufacturer grade MK2050. It features a PVD-applied dual coating of TiSiN and TiAlN for thermal resistance and wear protection during demanding milling operations. The parallelogram-shaped, single-sided insert has a positive rake angle of 4 degrees, a 15.20-degree relief angle, a T-Land cutting edge style, and delivers two cutting edges per insert. With an inscribed circle of 0.4016 inches and a thickness of 0.2366 inches, it is engineered for precision face and shoulder milling applications in production environments. Installation is performed by licensed machinists and CNC tooling technicians.

This insert is designed primarily for milling cast iron, steel, and hard materials, making it well-suited for both roughing and finishing passes where edge security and coating durability are critical. It fits the R217.69-XO16 and R220.69-XO16 SECO cutter series, confirming direct compatibility with those tool bodies. Right-hand cutting geometry and the MD14 chip breaker geometry support controlled chip evacuation at moderate to high feed rates. Typical applications include horizontal and vertical machining centers in job-shop and production-floor environments.

Key Features

• Solid carbide medium-grain substrate with PVD-applied TiSiN and TiAlN dual coating for heat and wear resistance
• XOMX160508TR-MD14 designation per ISO and ANSI standards — direct drop-in for compatible SECO tool bodies
• Positive rake angle (4 degrees) with T-Land cutting edge reduces cutting forces on cast iron and steel
• MD14 chip breaker geometry supports efficient chip control across a range of feed rates and depths
• Two cutting edges per insert; right-hand orientation; screw-mounted insert holding method
• Maximum depth of cut of 0.6063 inches with a cutting edge effective length of 0.6063 inches

Compatibility

Compatible with SECO cutter series R217.69-XO16 and R220.69-XO16. Designed for milling applications involving cast iron (ISO material code K), steel (ISO code P), and hard materials (ISO code H).

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Before changing inserts, power down the spindle and follow lockout/tagout procedures per applicable shop safety standards. Seat the insert fully against the pocket walls and tighten the clamping screw to the tool body manufacturer's specified torque using calibrated tooling — do not overtighten, as this can fracture the carbide substrate. Inspect the insert pocket for debris or damage before seating a new insert.
