Value Collection 102503 TPG221 Carbide Turning Insert

Product Description

The VALUE COLLECTION 102503 is a solid carbide, uncoated turning insert designed for precision lathe and turning center operations. Manufactured to ANSI insert code TPG221 and ISO code TPG110304, this triangular insert features a 60-degree included angle, a 1/4-inch inscribed circle, a 1/8-inch thickness, and a 1/64-inch corner radius. The flat-top chip breaker geometry and positive side clearance make it well-suited for finishing and semi-finishing cuts on a range of workpiece materials. Carbide grade C5/C6 provides the hardness and wear resistance required for consistent performance in production turning environments. This insert is installed by machinists and toolroom professionals using standard TPG-style clamp-type toolholders.

This insert is intended for use in clamp-style turning toolholders that accept TPG-style inserts. It is appropriate for machining P-category workpiece materials, including steels and similar ferrous metals, in both job-shop and production turning applications. The bright, uncoated finish makes it a practical choice for operations where a coated grade is not required or where re-grinding compatibility is a consideration. Sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by machinists using standard insert clamp toolholders rated for TPG-style inserts. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert fully in the pocket and verify the clamp is torqued per the toolholder manufacturer specifications before resuming cuts. Inspect the insert pocket and clamp for wear or debris that could affect seating and dimensional accuracy.
