Seco 74016732 Milling Insert SPMX070304-75 T25M Carbide

Product Description

The SECO 74016732 is a solid carbide milling insert identified by manufacturer part number SPMX070304-75, grade T25M, designed for high-performance indexable milling operations. The insert features a square shape with a 90-degree included angle, neutral hand orientation, and a positive rake angle of 16 degrees with a T-Land cutting edge style. A TiCN coating applied via CVD process improves wear resistance and thermal stability during cutting. With four usable cutting edges per insert and a corner radius of 0.0157 inches, this insert delivers consistent performance in demanding milling applications across a variety of workpiece materials.

This insert is suited for milling steel, stainless steel, superalloys, and titanium in medium-grain material grade applications. It fits SECO cutter series R218.19-3, R417.19-3, and R218.19. The 75 chip breaker geometry supports controlled chip evacuation during face milling and shoulder milling operations. Installation is typically performed by machinists and tooling technicians in production or job-shop environments. The insert is held in the cutter body by a screw-type clamping method, consistent with SPMX-07 series toolholders. ISO standard ANSI code SPMX070304-75 applies.

Key Features

• TiCN coating applied via CVD process for improved wear and heat resistance
• 4 cutting edges per insert maximizing tooling value per unit
• Positive rake angle of 16 degrees with T-Land edge style for controlled cutting action
• Corner radius of 0.0157 inches (1/64 inch) for fine surface finish capability
• 75 chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium

Compatibility

Compatible with SECO milling cutter series R218.19-3, R417.19-3, and R218.19. Insert uses screw-type holding method standard to SPMX-07 series bodies. ANSI and ISO code: SPMX070304-75.

Installation Notes

This insert is installed and indexed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat and torque the clamping screw per the toolholder manufacturer specification. Inspect the insert pocket and seating surface for debris or damage before installing a new insert to ensure proper seating and runout.
