Value Collection 112076536 Turning Insert TPU321 TCN55

Product Description

The VALUE COLLECTION 112076536 is a solid carbide turning insert designed for use on CNC lathes and turning centers. Manufactured to ANSI Insert Code TPU321 and ISO Insert Code TPU160304, this triangular insert features a TiC and TiN coating applied via CVD process, providing wear resistance and extended tool life across a range of workpiece materials. The inscribed circle measures 3/8 inches, insert thickness is 1/8 inch, and the corner radius is 1/64 inch. With a 60-degree included angle and an 11-degree relief angle, this insert is suited for general-purpose turning operations. It is installed by machinists and toolroom professionals working on manual or CNC turning equipment.

This insert is intended for use in positive-side-clearance toolholders with clamp-style insert holding, compatible with TPU-style toolholder seats. It is rated for use on primary workpiece material codes M and P, covering steel, stainless steel, and similar ferrous alloys. The flat-top chip breaker geometry and positive clearance angle support clean chip flow during medium-duty turning passes. Sold individually with a minimum order quantity of 10 units.
