Hertel 1001184 Turning Insert DPMT2151LF HC210 Carbide

Product Description

The HERTEL 1001184 is a solid carbide turning insert with a DPMT style geometry and HC210 manufacturer grade. It features a physical vapor deposition (PVD) TiN coating and a positive rake angle, making it suited for precision external turning operations. The insert measures 7.75 mm (0.3051 inches) in length with a 1/4 inch (0.2500 inch) inscribed circle and a 1/64 inch (0.0160 inch) corner radius. The 55-degree diamond shape and screw-on holding method make this insert a standard choice for CNC lathe toolholders. Licensed machinists and toolroom operators handling turning applications on stainless, nonferrous, and superalloy materials will find this insert appropriate for their setups.

This insert is designed for turning operations on primary workpiece materials classified as M (stainless steel), N (nonferrous metals), and S (superalloys and titanium), with secondary suitability for K-grade cast iron. It is appropriate for light to medium depth-of-cut passes up to 1.25 mm (0.0492 inches). The screw-on holding method fits standard DPMT-compatible toolholders used in production and job-shop turning environments, both CNC and manual.

Key Features

• Solid carbide construction with PVD TiN coating for extended tool life on stainless, nonferrous, and superalloy workpieces
• 55-degree diamond insert shape (D) with positive rake geometry for lower cutting forces
• 1/4 inch inscribed circle with 1/64 inch corner radius for fine-tolerance finishing passes
• Screw-on holding method for secure seating and repeatable indexing in DPMT toolholders
• Maximum depth of cut of 1.25 mm (0.0492 inches) supporting light to medium turning passes
• HC210 grade with T-style chip breaker for controlled chip evacuation

Compatibility

Designed as a screw-on replacement turning insert for DPMT-style toolholders compatible with 55-degree diamond inserts having a 1/4 inch inscribed circle. Consult your toolholder documentation to verify DPMT2151 seat and screw compatibility before installing.

Installation Notes

This insert is installed and indexed by qualified machinists or toolroom technicians familiar with CNC or manual lathe toolholder systems. Always de-energize and lock out the machine before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the clamping screw — do not overtighten. Inspect the insert seat and clamping screw for wear or debris before seating a new insert.
