Hertel 1001198 TPG221 HC210 Carbide Turning Insert

Product Description

The HERTEL 1001198 is a solid carbide turning insert in the TPG221 style, designed for precision metal turning operations on CNC and manual lathes. Manufactured to the KENDEX series standard, this insert carries a TiN (titanium nitride) coating applied via PVD process, which improves surface hardness and wear resistance during continuous and interrupted cuts. The triangular 60-degree geometry with a neutral hand orientation makes it a versatile choice for general-purpose turning. It features a 1/4-inch inscribed circle and a 1/64-inch corner radius, with an insert length of 11 mm (0.4331 inches) and a thickness of 1/8 inch (0.1250 inches).

This insert is suited for turning operations on stainless steel, non-ferrous metals, and high-temperature alloys, corresponding to workpiece material groups M, N, and S as primary, and K as secondary. The positive rake geometry and clamp-style holding method make it appropriate for finishing and light roughing passes where controlled chip formation and dimensional accuracy are priorities. It is sold individually but carries a minimum order quantity of 10 units, making it suitable for shop-stock replenishment in production machining environments.

Key Features

• Solid carbide construction with TiN coating via PVD process for extended tool life
• TPG221 style with 60-degree triangular geometry and neutral hand orientation
• 1/4-inch inscribed circle with 1/64-inch corner radius for precision turning
• Positive rake angle for reduced cutting forces on compatible workpiece materials
• Clamp-style insert holding method for secure, repeatable seating in the toolholder
• KENDEX series designation for compatibility with corresponding toolholders and insert pockets

Compatibility

Designed as a direct-fit replacement for TPG221-style insert seats in KENDEX series toolholders. Compatible with toolholders specifying Tolerance Code G, Clearance Code P, and clamp-style holding for triangular inserts with a 1/4-inch inscribed circle.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine fully powered down and the spindle locked before seating or replacing inserts. Use the appropriate torx or hex key to secure the clamp to the manufacturer-recommended feel without over-torquing, which can crack the carbide. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Follow your machine tool manufacturer guidelines and applicable shop safety procedures when handling sharp carbide tooling.
