Hertel 1000724 Turning Insert RCMT21.50 HC210 Carbide

Product Description

The HERTEL 1000724 is a round turning insert in the RCMT21.50 style, manufactured from solid carbide with a TiN (titanium nitride) PVD coating. It carries the HC210 manufacturer grade and is designed for use in CNC and manual turning operations. The insert features a neutral hand orientation, a 7-degree relief angle, and a 0.25 inch inscribed circle diameter. With a maximum depth of cut of 0.0492 inches (1.25 mm) and a 0.094 inch thickness, it is suited for finish to semi-finish turning passes. Screw-style holding locks the insert securely in compatible toolholders. Licensed machinists and CNC turning specialists are the primary installers.

This insert is intended for turning operations on a range of workpiece materials. Its primary workpiece material classifications are M (stainless steel), N (non-ferrous), and S (heat-resistant superalloys). Secondary workpiece material classification is K (cast iron). Material grades C2 and C4 apply. The RCMT style with round insert shape and chip breaker code T makes it appropriate for profiling, contouring, and copy-turning applications in production and job-shop environments, both on CNC lathes and live-tooling setups.

Key Features

• Solid carbide substrate with PVD TiN coating for wear resistance on stainless, non-ferrous, and superalloy materials
• Round insert shape (RCMT) with neutral hand — fits both right-hand and left-hand toolholders
• 7-degree relief angle (clearance code C) reduces rubbing on curved profiles
• Tolerance code M for consistent seating and repeatable tool offset
• Screw-style insert holding method for positive clamping without top clamp interference
• Chip breaker style T for controlled chip formation at moderate feed rates

Compatibility

Designed as an OEM-style replacement insert for toolholders accepting RCMT21.50 round turning inserts with screw-style clamping, consistent with ISO and ANSI insert seating standards for this insert size and shape code.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturers specified torque — do not overtighten, as carbide inserts are brittle and can crack under excessive clamp force. Inspect the insert pocket and clamping screw for debris or damage before seating a new insert.
