Dorian Tool 73310195431 Solid Carbide Milling Insert

Product Description

The DORIAN TOOL 73310195431 is a solid carbide, PVD-coated triangular milling insert designed for metal cutting applications in milling operations. Built to the ANSI/ISO designation TDEX-110208-XDEN-DPP30UM, this insert features a positive rake angle and a 15-degree relief angle that reduce cutting forces and help extend tool life when machining steel. The DPP chip breaker geometry promotes controlled chip evacuation, which is critical in continuous milling cuts. At 0.094 inches (2.39 mm) thick with an 11 mm inscribed circle diameter, this is a compact insert suited for light to medium material removal. It is installed by qualified machinists and CNC operators in production and job-shop environments.

This insert is intended for primary use on steel workpieces, corresponding to ISO material group P, with a manufacturer grade rating of DPP30UM covering P15-P30 material grades. The neutral hand orientation makes it compatible with a range of TDEX-series toolholders. Typical applications include face milling, shoulder milling, and general-purpose steel cutting on CNC machining centers and manual milling machines where screw-clamped insert retention is used.

Key Features

• Solid carbide construction with PVD coating for wear resistance on steel
• Triangular insert shape with 60-degree included angle and TDEX series geometry
• Positive rake and 15-degree relief angle reduce cutting forces
• DPP chip breaker for controlled chip formation in steel cutting
• Screw-clamped single-sided insert for secure toolholder retention
• Corner radius of 0.030 inches (0.76 mm) for balanced edge strength and surface finish

Compatibility

Designed as a screw-mount replacement insert for TDEX-series milling toolholders accepting 11 mm triangular inserts with a 0.1118-inch hole diameter. Verify toolholder seat dimensions and insert pocket geometry before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before accessing the insert pocket. Use the appropriate torx or hex key to remove the clamping screw, seat the insert fully against the pocket locating surfaces, and torque the screw per the toolholder manufacturer specification. Inspect the insert pocket and clamping screw for wear or damage each time an insert is changed.
