Value Collection TCN39510M Turning Insert RD8P Carbide

Product Description

The VALUE COLLECTION TCN39510M is a solid carbide turning insert designed for CNC and manual lathe applications. This is a round-profile (Style RD) insert with an ANSI and ISO code of RD8P, carrying a manufacturer grade of TCN55 with a titanium nitride (TiN) coating for improved wear resistance and heat dissipation. The inscribed circle measures 0.5 inches (12.70 mm), and insert thickness is 0.125 inches. It is held by screw-on mounting and features a positive side clearance with a 15-degree relief angle. These inserts are sold individually but require a minimum order of 10 pieces.

This insert is suited for turning operations on ferrous metals, including steel and stainless steel classifications, as indicated by the primary workpiece material codes P and M. It performs in both roughing and finishing passes depending on feed rate and depth of cut selection. The round insert geometry distributes cutting forces evenly around the edge, extending useful tool life in interrupted and continuous cut scenarios. Typical applications include OD turning on production lathes in machine shops, job shops, and maintenance environments.

Key Features

• Solid carbide construction with TiN coating for extended edge life and heat resistance
• Round insert shape (Style RD) distributes cutting forces evenly across the cutting edge
• Positive side clearance with 15-degree relief angle reduces cutting pressure on workpiece
• Screw-on holding method provides secure, repeatable insert indexing
• ANSI and ISO size code 8P ensures cross-reference compatibility with standard toolholders
• Material grade C5 carbide suited for steel and stainless steel workpiece materials

Compatibility

Designed for use in standard screw-clamp toolholders accepting RD8P round turning inserts per ANSI and ISO size code 8P. Compatible with toolholders designed for a 0.5-inch inscribed circle round insert with a 0.125-inch hole diameter.

Installation Notes

Installation should be performed by a qualified machinist with the machine fully powered down and spindle locked before changing inserts. Use the appropriate torx or hex key to torque the clamping screw according to the toolholder manufacturer specifications. Inspect the insert pocket and seating surface for chips or debris before seating the insert. Always index to a fresh cutting edge or replace the insert when flank wear reaches the limit for the operation.
