Dorian Tool 73310195498 Milling Insert Carbide Tdex

Product Description

The DORIAN TOOL 73310195498 is a solid carbide, PVD-coated triangular milling insert designed for demanding metal removal operations in cast iron applications. Built to the TDEX series standard, this insert carries manufacturer grade DNP10HM with a K10 material grade and features a positive rake geometry paired with an 11-degree relief angle. The inscribed circle measures 0.374 inches (9.50 mm), thickness is 0.094 inches (2.39 mm), and the corner radius is 0.008 inches (0.20 mm). It uses a screw-type holding method and is a single-sided insert. The DNP chip breaker geometry promotes controlled chip flow during face milling and shoulder milling operations.

This insert is intended for milling cast iron workpieces in production or job-shop environments. The TDEX series geometry and PVD coating are well-suited for moderate to high cutting speeds where tool life and surface finish consistency matter. The neutral hand orientation allows flexible application across compatible TDEX toolholders. Typical users include CNC machinists and toolroom technicians working with gray iron, ductile iron, and similar K-grade materials.

Key Features

• Solid carbide construction with PVD coating for wear resistance in cast iron cutting
• Positive rake, 11-degree relief angle reduces cutting forces and edge chipping
• DNP chip breaker promotes efficient chip evacuation during milling
• Triangular insert shape (45-degree included angle) in TDEX series for broad toolholder compatibility
• Corner radius of 0.008 inches (0.20 mm) for controlled edge geometry
• Screw-type clamping for secure, repeatable insert seating

Compatibility

Designed for use in TDEX-series milling toolholders accepting a size 09 triangular insert with a 0.1118-inch hole diameter. ANSI and ISO code: TDEX-090202-XDEN-DNP10HM. Optimized for primary workpiece material code K (cast iron).

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. 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, as carbide inserts are brittle and can fracture under excessive clamp load. Inspect the insert pocket and seating surface for chips or debris before installing a new insert.
