Dorian Tool 73310195453 Carbide Milling Insert Triangle

Product Description

The DORIAN TOOL 73310195453 is a solid carbide, PVD-coated triangular milling insert designed for metal removal on steel workpieces in milling applications. Identified by ANSI and ISO code TDEX-160308-XDEN-DPP30UM, this insert features a positive rake geometry with a 15-degree relief angle and a DPP chip breaker for efficient chip control. It measures 0.125 inches thick with an inscribed circle of 0.375 inches. The manufacturer grade is DPP30UM, placing it in the P15-P30 material grade range. Installation is screw-held, and the insert is single-sided with a neutral hand orientation. Machinists and tooling technicians working on CNC or manual milling operations install this insert in compatible TDEX-series toolholders.

This insert is suited for milling steel and similar P-grade ferrous materials in both production and job-shop environments. The TDEX series geometry and DPP chip breaker make it appropriate for light to medium milling passes where chip control and edge consistency are critical. The 60-degree included angle of the triangular insert provides three usable cutting edges per insert, improving cost-per-edge efficiency. It is typically used in face milling, shoulder milling, and general-purpose milling operations on steel components.

Key Features

• Solid carbide substrate with PVD coating for extended tool life on steel
• Triangular insert shape with 60-degree included angle - three cutting edges per insert
• Positive rake and 15-degree relief angle reduce cutting forces
• DPP chip breaker geometry promotes effective chip evacuation
• Screw-held mounting for secure, repeatable insert positioning
• Corner radius of 0.030 inches (0.76 mm) for controlled edge geometry

Compatibility

Designed as an OEM-style replacement insert for TDEX-series milling toolholders accepting size 160308 triangular inserts with screw-held retention.

Installation Notes

This insert is installed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to seat the clamping screw - do not overtighten. Inspect the toolholder pocket and seating surfaces for wear or debris before installing a new insert.
