Seco 74016468 Milling Insert APFT1604PDR-M12 T25M Carbide

Product Description

The SECO 74016468 is a solid carbide milling insert carrying the manufacturer part number APFT1604PDR-M12 and grade designation T25M. This single-sided, right-hand parallelogram insert features a CVD-applied TiCN coating over a medium grain carbide substrate, delivering the hardness and thermal resistance required for productive face and shoulder milling operations. With two cutting edges, a positive 15-degree rake angle, and a honed cutting edge style, the insert promotes lower cutting forces and clean chip formation. The 0.0315-inch corner radius and M12 chip breaker geometry suit a range of material removal rates in milling applications. Installation and tool change are handled by machinist-level tooling personnel using a screw clamping method.

This insert is suited for milling steel, stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material groups P, M, and S. It is designed for use in shoulder and face milling applications where controlled chip breaking and consistent edge geometry are critical. The APFT1604PDR-M12 is compatible with SECO cutter series R217.69-16 and R220.69-16. Maximum depth of cut reaches 0.6220 inches, making it appropriate for moderate to aggressive passes in production milling environments.

Key Features

• CVD TiCN coating over medium grain solid carbide substrate for thermal wear resistance
• Positive rake angle of 15 degrees reduces cutting forces and heat generation
• M12 chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium
• Two cutting edges per insert extend usable tool life
• Honed cutting edge style improves edge stability on interrupted and continuous cuts
• Screw holding method ensures secure seating in compatible milling cutter bodies

Compatibility

Compatible with SECO cutter series R217.69-16 and R220.69-16. Designed for right-hand milling operations on steel, stainless steel, superalloys, and titanium workpiece materials per ISO material groups P, M, and S.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key driver specified by the cutter body manufacturer when tightening the clamping screw — do not over-torque. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert to ensure proper contact and runout control.
