Dorian Tool 73310171918 Carbide Turning Insert TCMT32.52

Product Description

The DORIAN TOOL 73310171918 is a TCMT32.52-PEM carbide turning insert in grade DPC25UT, designed for external and internal turning operations on steel and stainless steel workpieces. It features a 60-degree triangular shape with a positive rake and positive side clearance, a 3/8-inch inscribed circle, and a 1/32-inch corner radius. The multilayer CVD coating sequence of Al2O3/TiCN/Al2O3/TiCN delivers high wear resistance combined with toughness across a broad range of cutting conditions. This insert is held in place by a screw-clamp toolholder and is installed by machinists and CNC operators in production turning environments.

This insert is suited for turning steel (P-grade workpieces) and stainless steel (M-grade workpieces) in both roughing and finishing passes where wear resistance and edge toughness are priorities. The PEM chip breaker geometry controls chip flow effectively across moderate to aggressive depths of cut up to 0.236 inches. The neutral hand orientation makes it compatible with a wide range of TCMT-style toolholders. It carries both ANSI designation TCMT32.52 and ISO designation TCMT16T308, allowing straightforward cross-referencing against existing tool libraries.

Key Features

• Multilayer CVD coating (Al2O3/TiCN/Al2O3/TiCN) for high wear resistance and thermal stability
• 60-degree triangular insert shape (T) with positive rake and 7-degree relief angle
• 3/8-inch (0.3750 inch) inscribed circle with 1/32-inch (0.0313 inch) corner radius
• PEM chip breaker geometry rated for steel and stainless steel applications
• Maximum depth of cut of 0.236 inches (5.99 mm)
• Dual-standard compliance: ANSI TCMT32.52 and ISO TCMT16T308
• Screw insert-holding method with honed cutting edge for consistent engagement

Compatibility

Designed as an OEM-style replacement for TCMT-style screw-clamp turning toolholders accepting a 3/8-inch inscribed circle triangular insert per ANSI and ISO standards. Compatible with steel and stainless steel workpiece materials (P and M grade classifications).

Installation Notes

Installation is performed by a qualified machinist or CNC technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver specified by the toolholder manufacturer when securing the clamping screw to avoid insert cracking or seat damage. Inspect the toolholder pocket and seating surface for chips or wear before seating a new insert.
