Dorian Tool 73310195457 Milling Insert Solid Carbide

Product Description

The DORIAN TOOL 73310195457 is a solid carbide, PVD-coated triangular milling insert designed for indexable milling operations in cast iron applications. It carries the ANSI/ISO designation TDEX-160308-XDEN-DNP10HM and belongs to the TDEX series. The insert features a positive rake geometry with a 15-degree relief angle, a 0.030-inch corner radius, and a DNP chip breaker configuration. At 0.125 inches thick with a 0.375-inch inscribed circle, it is a compact, single-sided insert intended for precision milling work. Installation and tooling selection are handled by licensed machinists and CNC setup technicians working with compatible indexable milling toolholders.

This insert is engineered for milling cast iron workpieces, corresponding to ISO material group K and material grade K10. It is suited for use in light to medium milling passes where controlled chip formation and edge integrity are critical. The neutral hand orientation allows flexible positioning in compatible TDEX-series toolholders. Typical applications include face milling, shoulder milling, and profile milling operations on cast iron components in production and job-shop environments.

Key Features

• Solid carbide substrate with PVD coating for extended tool life in cast iron
• Triangular insert shape with 60-degree included angle for versatile milling geometries
• DNP chip breaker promotes reliable chip control at productive feed rates
• Positive rake and 15-degree relief angle reduce cutting forces on the workpiece
• Neutral hand orientation fits a wide range of TDEX-series indexable toolholders
• Single-sided design ensures consistent edge presentation at each index position

Compatibility

Designed for use in TDEX-series indexable milling toolholders that accept size 16 triangular inserts with a screw-clamp holding method. Consult the toolholder manufacturer specifications to confirm pocket geometry and screw compatibility before installation.

Installation Notes

Indexable insert replacement is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before handling inserts. Use the correct torque driver or hex key for the insert clamping screw as specified by the toolholder manufacturer. Inspect the insert pocket seat for chips or debris before seating the new insert to ensure proper clamping and runout.
