Sandvik Coromant 5916220 Round Turning Insert Rpgn Carbide

Product Description

The SANDVIK COROMANT 5916220 is a solid carbide, uncoated turning insert designed for precision metal cutting operations on CNC lathes and turning centers. Featuring a round insert shape (ISO code R) with a RPGN style designation, this insert carries an inscribed circle diameter of 0.375 inches and an insert thickness of 0.125 inches. The bright, uncoated carbide substrate suits applications where coating interaction with the workpiece material is a concern or where a sharp, consistent edge is required. It is installed and replaced by machinists and toolroom technicians during routine insert indexing and toolholder maintenance.

This insert is suited for turning applications in job shops, production machining environments, and toolroom settings handling a range of materials where uncoated solid carbide performs effectively. The RPGN insert style uses a clamp-type holding method with a P clearance code and G tolerance code, making it compatible with standard toolholders engineered for RPGN-style round inserts. Its compact round geometry is commonly used for profiling, contour turning, and finishing passes where a multi-directional cutting edge is advantageous.

Key Features

• Round insert shape (Shape Code R) provides a continuous cutting edge suitable for profiling and contour turning
• Solid carbide construction with bright, uncoated finish for consistent edge sharpness
• RPGN insert style with clamp-type holding method for secure seating in compatible toolholders
• Inscribed circle of 0.375 inches and thickness of 0.125 inches for precise fitment in RPGN-designated toolholder pockets
• P clearance code and G tolerance code per ISO insert designation standards
• ISO code RPGN090300E 6060 for straightforward cross-reference and toolholder matching

Compatibility

Designed for use in toolholders specifying RPGN-style round turning inserts with a 0.375 inch inscribed circle. Verify toolholder pocket geometry, clamping method, and tolerance requirements against the ISO code RPGN090300E 6060 before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or toolroom technician with the machine fully powered down, spindle locked, and all motion axes secured. Use the appropriate torx or hex key to tighten the clamp screw to the toolholder manufacturer's specified procedure — do not overtighten. Inspect the insert pocket and clamp for wear or debris before seating the new insert. Always follow your facility's lockout/tagout procedures before servicing any cutting tool assembly.
