Osg 7813011 Round Milling Insert XP2040 Tialn Rpht

Product Description

The OSG 7813011 is a solid carbide round milling insert in the RPHT series, designed for high-performance milling of stainless steel and steel workpieces. Manufactured to grade XP2040 and coated with TiAlN via a PVD process, this insert delivers heat resistance and edge durability in demanding cutting applications. The round insert shape (ANSI/ISO code RPHT1204MOEN-GL) provides a 360-degree included angle with four usable cutting edges. At 0.1874 inches thick with a 0.4724-inch inscribed circle, it fits standard RPHT-style toolholders. The GL chip breaker geometry and honed cutting edge style suit finishing and semi-finishing operations on stainless and alloy steel components.

This insert is suited for milling operations in manufacturing, job shop, and production environments where stainless steel and steel are the primary workpiece materials. The positive rake and 11-degree relief angle reduce cutting forces and improve chip evacuation, making this insert a practical choice for shoulder milling, face milling, and similar operations on CNC machining centers. It is installed by machinists and tooling technicians using the screw-holding method standard to RPHT toolholders.

Key Features

• Solid carbide substrate with PVD TiAlN coating for thermal resistance and extended tool life
• Four cutting edges per insert on a round, single-sided RPHT geometry
• GL chip breaker optimized for stainless steel and steel applications
• Positive rake angle with honed cutting edge reduces cutting forces
• Meets ANSI and ISO standards; ANSI/ISO code RPHT1204MOEN-GL
• Screw-held insert style for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use in RPHT-style milling toolholders accepting a size 1204 round insert with a 0.4724-inch inscribed circle. Compatible primary workpiece materials are stainless steel (ISO material code M) and steel (ISO material code P).

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully in the pocket and tighten the clamp screw to the toolholder manufacturer's specification using the appropriate Torx or hex key. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and edge alignment.
