Hertel 1000455 Turning Insert DPMT3252LF HC210 Carbide

Product Description

The HERTEL 1000455 is a DPMT3252LF-style solid carbide turning insert coated with titanium nitride (TiN) via a PVD process, designed for single-point turning operations on CNC lathes and turning centers. It features a 55-degree diamond insert shape, a 3/8-inch inscribed circle (0.3750 inches), and a 1/32-inch corner radius (0.0310 inches). The HC210 manufacturer grade with positive rake geometry provides sharp cutting action and good wear resistance. Insert length is 11.63 mm (0.4579 inches) and insert thickness is 5/32 inch (0.1563 inches). This screw-on style insert is installed by licensed machinists and CNC operators in production and job-shop environments.

This insert is suited for turning stainless steel, non-ferrous metals, and superalloys, corresponding to workpiece material designations M, N, and S, with secondary suitability for cast materials (K). It is commonly applied in finishing and semi-finishing passes where controlled chip formation and surface finish are priorities. The T-style chip breaker helps manage chip flow at moderate depths of cut. Maximum depth of cut is 1.25 mm (0.0492 inches). Typical applications include shaft turning, facing, and contour work on production lathes running at elevated surface speeds.

Key Features

• Solid carbide substrate with TiN PVD coating for wear resistance and extended tool life
• 55-degree diamond insert shape (Insert Shape Code D) for versatile turning and facing operations
• Positive rake geometry with T-style chip breaker for efficient chip control
• Screw-on holding method with 0.1732-inch hole diameter for secure, repeatable indexing
• Relief angle of 11 degrees with clearance code P and tolerance code M
• Maximum depth of cut of 1.25 mm (0.0492 inches) suited for finishing and light semi-finishing passes

Compatibility

Designed as a screw-on style replacement insert for DPMT-format toolholders accepting a 3/8-inch inscribed circle, 55-degree diamond insert. Material grade designations C2 and C4 indicate compatibility with tooling systems specified for those carbide grades. Verify toolholder seat geometry and screw size before installation.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for the screw-on clamping screw to avoid seat damage or insert fracture — consult the toolholder manufacturer specification for fastener torque. Inspect the insert pocket and seating surface for chips or debris before seating the new insert.
