Hertel 1000731 RPG42 HC335 Carbide Turning Insert 0.5 in Ic

Product Description

The HERTEL 1000731 is a solid carbide turning insert in the RPG42 style, designed for single-point turning operations on CNC and manual lathes. It carries a CVD-applied multilayer coating of TiC, TiCN, and TiN over a carbide substrate graded HC335, placing it in the C5 and C6 material grade range. The insert features a round shape (shape code R) with a 0.5 inch inscribed circle and a 0.125 inch thickness. Positive rake geometry and an 11-degree relief angle reduce cutting forces and help manage heat at the cutting edge. It is sold individually but subject to a minimum order quantity of 10 units.

This insert is suited for turning operations on steel and stainless steel workpiece materials, corresponding to ISO P and M material classifications. The KENDEX series designation indicates use in compatible clamp-style toolholders with a P clearance code and G tolerance code. Typical applications include finish and semi-finish turning on components where controlled chip formation and coating durability are priorities. The maximum depth of cut is 0.0492 inch (1.25 mm), making this insert appropriate for lighter-engagement turning passes rather than heavy roughing.

Key Features

• CVD multilayer coating: TiC, TiCN, and TiN for wear and heat resistance
• Solid carbide substrate, HC335 grade (C5/C6 equivalent)
• Round insert shape, 0.5 inch inscribed circle for versatile contouring
• Positive rake with 11-degree relief angle reduces cutting forces
• Clamp-held retention method with G tolerance code for consistent seating
• Maximum depth of cut 0.0492 inch (1.25 mm) — optimized for finish and semi-finish passes

Compatibility

Designed for use in KENDEX series clamp-style turning toolholders that accept RPG42 round inserts with a P clearance code and G tolerance code. Confirm toolholder seat geometry and clamp configuration before ordering.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamp specifications. Power down and lock out the machine spindle before changing inserts. Inspect the toolholder pocket and clamp for wear or debris prior to seating the new insert. Handle carbide inserts with care — edges chip under impact and should not contact hard surfaces during installation.
