Value Collection 6-RPG-322 Round Milling Insert Carbide

Product Description

The VALUE COLLECTION 6-RPG-322 is a solid carbide milling insert designed for material removal operations in CNC and manual milling applications. Conforming to ANSI standard RPGN 32, this round insert features a neutral hand orientation, positive rake geometry, and a bright uncoated finish suited for cutting non-ferrous metals. The inscribed circle measures 0.375 inches, thickness is 0.125 inches, and the corner radius is 0.1875 inches. With four cutting edges and a flat-top chip breaker configuration, it delivers consistent chip control at each index. Licensed machinists and CNC operators working in production or job-shop environments are the primary installers of this insert type.

This insert is intended for milling non-ferrous workpiece materials such as aluminum, copper, and brass alloys. The C2 material grade and uncoated carbide substrate perform best where sharp edges and low friction are priorities, reducing built-up edge on soft, gummy materials. The RPGN 32 profile fits tool holders designed for round, clamp-style inserts with an 11-degree relief angle. It is sold individually and ordered in multiples of 10, making it suitable for both shop-stock replenishment and production-run tooling programs.

Key Features

• Round insert shape (RPGN) with 360-degree included angle and four indexable cutting edges
• Solid carbide construction, C2 material grade, optimized for non-ferrous metal cutting
• Bright uncoated finish minimizes friction and prevents aluminum adhesion
• Positive rake and 11-degree relief angle reduce cutting forces on soft workpiece materials
• Flat-top chip breaker geometry for predictable chip formation
• Neutral hand orientation fits a wide range of RPGN-compatible clamp-style toolholders

Compatibility

Designed as an OEM-style replacement or shop-stock insert for clamp-style round insert toolholders accepting the RPGN 32 ANSI insert style with a 0.375-inch inscribed circle diameter.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and manufacturer-specified clamp screw when securing the insert to avoid cracking the carbide substrate. Inspect the toolholder pocket and clamp for wear or debris before seating a new insert. Never use a damaged or chipped insert, as it can cause unpredictable tool failure during a cut.
