Dorian Tool 73310195501 Carbide Milling Insert Tdex

Product Description

The DORIAN TOOL 73310195501 is a solid carbide coated milling insert designed for indexable milling applications in steel cutting operations. Manufactured to ANSI and ISO code TDEX-090204-XDEN-DPP30UM, this insert features a triangular shape with a 45-degree included angle and a positive rake geometry that promotes efficient chip formation. The PVD coating process delivers a hard, wear-resistant surface suitable for P15-P30 material grade applications. At 0.094 inches thick with a 0.374-inch inscribed circle, it is a compact, precision-ground insert for demanding milling work. Licensed HVAC and mechanical tradespeople as well as machining professionals who specify Dorian tooling will recognize the TDEX series geometry.

This insert is intended for use in TDEX-series indexable milling cutters targeting steel workpieces, classified under primary workpiece material code P. The DPP chip breaker geometry is suited for medium-depth milling passes in P15-P30 steels. The screw-held, single-sided, neutral-hand design makes it compatible with standard TDEX-090204 toolholders. It is used in production and job-shop environments where consistent tool life and surface finish on steel components are required.

Key Features

• Solid carbide substrate with PVD coating for extended wear resistance in steel cutting
• Triangular insert shape with 45-degree included angle and positive rake for reduced cutting forces
• DPP chip breaker geometry optimized for P15-P30 steel material grades
• Corner radius of 0.015 inches (0.38 mm) for controlled surface finish
• Screw-held, single-sided, neutral-hand mounting for secure seating in TDEX toolholders
• ANSI/ISO designation TDEX-090204-XDEN-DPP30UM for straightforward replacement ordering

Compatibility

Designed for use in TDEX-series indexable milling toolholders accepting insert size code 090204 with a hole diameter of 0.1118 inches. Confirmed primary workpiece material application is steel (material code P), covering P15-P30 grade steels. No additional specific toolholder model numbers were provided in the product data.

Installation Notes

Insert seating and replacement should be performed by qualified machinists or tooling technicians with the spindle powered down and the machine locked out per applicable safety procedures. Use the correct torque wrench and manufacturer-specified clamp screw to secure the insert without over-torquing, which can fracture carbide. Inspect the insert pocket and seating surface for debris or damage before installing a fresh insert. Handle solid carbide inserts carefully to avoid chipping edges prior to use.
