Value Collection ICR35170H RNMA64 Carbide Turning Insert

Product Description

The VALUE COLLECTION ICR35170H is a solid carbide turning insert designed for precision metal cutting on CNC lathes and manual turning centers. Manufactured to ANSI insert code RNMA64 and ISO insert code RNMA190600, this round-profile insert carries a 3/4 inch (0.7500 inch) inscribed circle diameter and a 1/4 inch (0.2500 inch) thickness. The bright, uncoated carbide construction suits applications where coating buildup would compromise dimensional accuracy or where re-grinding is part of the tooling program. The flat-top chip breaker geometry and negative side clearance make this insert appropriate for rigid, stable turning operations in a qualified toolholder. It weighs approximately 0.047 pounds per piece.

This insert is intended for turning ferrous workpiece materials, consistent with primary workpiece material code P, which covers carbon steels, alloy steels, and similar materials. Material grades C5 and C6 indicate suitability for finishing to semi-roughing passes on steel. The RNMA-style round insert is a common choice in facing, profiling, and contour turning where a full cutting-edge radius is preferred for smooth surface finishes and extended tool life under moderate chip loads. It is typically used by machinists and CNC operators in job shop and production environments.

Key Features

• ANSI insert code RNMA64, ISO code RNMA190600 for standardized toolholder compatibility
• Round insert shape (code R) provides a continuous cutting edge for profiling and facing
• Solid carbide construction, bright uncoated finish, suitable for re-grinding programs
• Flat-top chip breaker with negative side clearance for rigid, stable cutting
• Material grades C5 and C6 rated for steel turning applications
• Held by clamp and pin method for secure seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement or standard-grade insert for toolholders accepting RNMA-style round inserts with a 3/4 inch inscribed circle, 0.3120 inch hole diameter, clamp and pin holding method, and negative clearance geometry.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine power locked out per shop lockout/tagout procedures. Seat the insert fully against the pocket locating surfaces before clamping to prevent micro-movement during cutting. Inspect the toolholder pocket and seating surfaces for chips or wear before installing a new insert. Follow toolholder manufacturer torque recommendations for the clamping screw.
