Dorian Tool 73310195421 Solid Carbide Milling Insert

Product Description

The DORIAN TOOL 73310195421 is a solid carbide, PVD-coated triangular milling insert designed for metal removal in steel machining applications. It carries the ANSI/ISO designation TDEX-110204-XDEN-DPP30UM and is built around the TDEX series geometry. The insert features a positive rake angle, a 15-degree relief angle, and a neutral hand orientation, making it well suited for medium to semi-finishing passes on steel workpieces. At 0.094 inches thick with an 11 mm inscribed-circle width, this single-sided insert is secured via screw-holding method. The DPP chip breaker geometry helps control chip flow during cutting operations. Material grade is P15-P30, targeting a broad range of steel applications.

This insert is intended for use in milling operations on steel workpieces, classified under primary workpiece material code P. It fits toolholders in the TDEX series designed for triangular inserts with a 0.2500-inch inscribed circle. Typical users include CNC machinists, tool-and-die shops, and production machining operations where consistent chip control and tool life in steel cutting are priorities. The 60-degree included angle of the triangular geometry provides three usable cutting edges per insert.

Key Features

• Solid carbide substrate with PVD coating for wear resistance in steel machining
• Positive rake, 15-degree relief angle geometry reduces cutting forces
• DPP chip breaker promotes controlled chip evacuation during milling
• Three usable cutting edges per insert due to 60-degree triangular shape
• Screw-holding method ensures rigid insert retention in compatible toolholders
• P15-P30 material grade covers a wide range of steel cutting conditions

Compatibility

Designed for use in TDEX-series milling toolholders accepting triangular inserts with a 0.2500-inch inscribed circle and 0.094-inch insert thickness. ANSI/ISO code TDEX-110204-XDEN-DPP30UM identifies exact toolholder fitment requirements.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque driver for the insert screw to avoid stripping the seat or cracking the carbide. Inspect the pocket and screw for wear or debris before installing a fresh insert.
