Value Collection 112077936 Turning Insert TPU432 TCN55

Product Description

The VALUE COLLECTION 112077936 is a solid carbide turning insert designed for metal cutting operations on CNC lathes and manual turning centers. Carrying the ANSI insert code TPU432 and ISO code TPU220408, this triangular insert features a TiC and TiN multilayer CVD coating applied over a C5 through C7 carbide substrate. The 60-degree included angle, 11-degree relief angle, and positive side clearance geometry make it well suited for general-purpose external and internal turning. The inscribed circle measures 0.5 inches, insert length is 12.7 mm, insert thickness is 0.1875 inches, and the corner radius is 0.03125 inches (1/32 inch).

This insert is intended for machining ISO material groups M and P, covering a broad range of steel, stainless steel, and ferritic/martensitic alloys. The flat-top chip breaker geometry and positive clearance code suit medium to finishing pass depths of cut where chip control and surface finish are priorities. It is typically used in production turning environments by machinists and tooling technicians running volume part programs on CNC turning equipment.

Key Features

• ANSI code TPU432 and ISO code TPU220408 for straightforward toolholder matching
• CVD-applied TiC and TiN coating over solid carbide for wear resistance on steel and stainless
• 60-degree triangular insert shape provides three usable cutting edges per insert
• 11-degree relief angle with positive side clearance reduces cutting forces
• Flat-top chip breaker geometry for predictable chip flow on finishing and medium passes
• Clamp-style insert holding method compatible with standard TPU-style toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit insert for TPU-style clamp toolholders accepting ANSI size code 432 triangular inserts with a tolerance code U and clearance code P configuration.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Ensure the insert pocket and clamp are free of chips and debris before securing the insert to prevent micro-fracture at the cutting edge. Torque the clamp screw according to the toolholder manufacturer specifications, not inferred values.
