Value Collection 112076636 Turning Insert TPU322 TCN55

Product Description

The VALUE COLLECTION 112076636 is a solid carbide turning insert designed for use in CNC lathes and manual turning centers. Coated with TiC and TiN via a CVD process, grade TCN55 provides wear resistance and thermal protection during interrupted and continuous cuts. The insert follows ANSI code TPU322 and ISO code TPU160308, with a triangular shape (T), a 3/8-inch inscribed circle, 1/8-inch thickness, and a 1/32-inch corner radius. The flat-top chip breaker geometry and positive side clearance support clean chip flow across a range of cutting conditions. Machinists and CNC operators install this insert in compatible toolholders for turning operations on steel and stainless materials.

This insert is suited for turning operations on primary workpiece material codes M and P, covering general-purpose steels and stainless steels. The 60-degree included angle and 11-degree relief angle make it appropriate for lighter finishing and semi-finishing passes. It seats using a clamp-style holding method and fits toolholders dimensioned for the 322 ANSI insert size. Typical applications include shaft turning, facing, and contour work on production and job-shop lathes.

Key Features

• Solid carbide substrate with CVD-applied TiC and TiN coating, grade TCN55
• Triangular insert shape with 60-degree included angle and 11-degree relief angle
• Flat-top chip breaker for consistent chip control on steel and stainless cuts
• Positive side clearance reduces cutting forces on lighter-duty passes
• Clamp-style holding method for secure seating in standard TPU-style toolholders
• Meets ANSI size code 322 and ISO size code 160308 for cross-reference compatibility

Compatibility

Designed as an OEM-style replacement and standard insert for clamp-style toolholders dimensioned to ANSI size code 322 and ISO size code 160308, compatible with TPU-style insert pockets.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC technician with the machine powered down and the spindle locked. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer to seat the insert securely without overtightening. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Replace the insert at the first sign of edge wear, chipping, or dimensional drift in the finished workpiece.
