Kennametal 3066133 Milling Insert SDET120412PDENGDZ KC725M

Product Description

The KENNAMETAL 3066133 is a solid carbide milling insert with ISO designation SDET120412PDENGDZ and ANSI designation SDET433PDENGDZ, manufactured in the KC725M grade. It carries a TiAlN coating applied via PVD process, providing wear resistance suited to high-speed and interrupted cutting operations. The insert features a square shape with a 90-degree included angle, four usable cutting edges, a positive rake geometry, and a honed cutting edge style. The GDZ chip breaker and 15-degree relief angle make this insert effective for finishing and semi-finishing operations in steel, stainless steel, superalloys, and titanium. It is installed using a screw-holding method and is compatible with the KSSM cutter series.

This insert is intended for milling applications where material grades C5, C6, and C7 apply, covering workpiece materials coded P, M, and S — steel, stainless steel, superalloys, and titanium. It is suited for use in both production and job-shop environments where consistent chip control and surface finish are priorities. The neutral hand orientation gives it flexibility across multiple cutter body positions. It is sold individually but subject to a minimum order quantity of 5 units.

Key Features

• KC725M solid carbide grade with TiAlN PVD coating for wear and heat resistance
• Four cutting edges per insert for extended tool life per unit
• GDZ chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium
• Positive rake with 15-degree relief angle reduces cutting forces
• Honed cutting edge style improves edge toughness and reduces micro-chipping
• Compatible with KSSM cutter series; screw-mounted, neutral hand

Compatibility

Designed for use with the KSSM cutter series. ANSI code SDET433PDENGDZ and ISO code SDET120412PDENGDZ identify the insert geometry for cross-referencing with compatible toolholders and cutter bodies.

Installation Notes

Installation is performed by machinists or tooling technicians following standard insert-seating procedures for screw-clamped milling inserts. Ensure the cutter body pocket and seating surfaces are clean and free of chips or debris before seating the insert. Use the manufacturer-specified torque driver for the clamping screw to avoid over-torquing and damaging the insert or pocket. Always de-energize and lock out the spindle before changing inserts.
