Dorian Tool 73310195451 Carbide Milling Insert Tdex

Product Description

The DORIAN TOOL 73310195451 is a solid carbide, PVD-coated triangular milling insert designed for precision material removal in industrial machining applications. Built to ANSI and ISO code TDEX-160304-XDEN-DNP10HM, this insert features a positive rake angle and a 15-degree relief angle, which together reduce cutting forces and promote clean chip evacuation. The DNP chip breaker geometry and a 0.38 mm (0.015 inch) corner radius make this insert well-suited for consistent, controlled cuts in cast iron. With a thickness of 0.125 inches (3.18 mm) and an inscribed circle of 0.375 inches (9.53 mm), this is a compact, single-sided insert intended for use by machinists and toolroom professionals on CNC or manual milling equipment.

This insert is engineered primarily for cast iron workpiece materials, corresponding to ISO material group K. The TDEX series geometry with a neutral hand orientation makes it adaptable across a range of milling setups where triangular insert pockets are specified. Typical installation scenarios include face milling, shoulder milling, and indexable end mill bodies that accept the TDEX insert style. The insert size code 160304 and manufacturer grade DNP10HM should be verified against the toolholder specification before ordering to confirm proper seating and clamping.

Key Features

• Solid carbide substrate with PVD coating for extended wear resistance in cast iron applications
• Triangular insert shape with 60-degree included angle and TDEX series geometry
• Positive rake with 15-degree relief angle reduces cutting forces and promotes chip flow
• DNP chip breaker optimized for cast iron material group K (ISO classification)
• 0.38 mm corner radius (0.015 inch) for controlled surface finish at cutting edges
• Screw-held, single-sided insert with neutral hand for straightforward indexing

Compatibility

Designed for use in milling toolholders and insert bodies that accept the TDEX insert style with insert size code 160304. Verify toolholder pocket geometry and screw-clamp compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to secure the clamping screw - do not overtighten, as this can fracture the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before seating a new insert.
