Value Collection 112076509 Turning Insert TPU321 Carbide

Product Description

The VALUE COLLECTION 112076509 is a solid carbide turning insert designed for use in CNC and manual lathe operations. Manufactured to ANSI insert code TPU321 and ISO insert code TPU160304, this triangular-profile insert features an 11-degree relief angle and a flat-top chip breaker geometry. The 3/8-inch inscribed circle and 1/64-inch corner radius make it well suited for general-purpose turning where clean chip evacuation and edge consistency are required. Carbide construction in material grade C2 provides the hardness and wear resistance needed for consistent performance across a range of workpiece materials. Licensed machinists and CNC operators install this insert as part of routine tooling changeovers.

This insert is appropriate for turning applications involving cast iron, non-ferrous metals, non-metallic materials, and heat-resistant alloys, as indicated by primary workpiece material codes K, M, N, and S. It fits standard clamp-style toolholders designed for triangular inserts with positive side clearance and the TPU insert style. Typical use cases include facing, roughing, and light finishing passes on lathes in production machine shops, maintenance environments, and general metalworking facilities. Sold individually, with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction, material grade C2, for hardness and wear resistance
• ANSI insert code TPU321 and ISO insert code TPU160304 for standard toolholder compatibility
• 60-degree triangular insert shape with 11-degree relief angle and positive side clearance
• 1/64-inch corner radius for controlled edge geometry on turning operations
• Flat-top chip breaker design supports chip control across varied feed rates
• Compatible with workpiece material codes K, M, N, and S

Compatibility

Designed for use in clamp-style toolholders that accept TPU-style triangular turning inserts with positive clearance geometry, ANSI size code 321, and ISO size code 160304.

Installation Notes

Installation is performed by machinists or CNC tooling technicians during standard insert indexing or changeover. The machine spindle must be fully stopped and the toolholder secured before removing or seating an insert. Use the appropriate torx or clamp screw driver as specified by the toolholder manufacturer to seat the insert firmly without over-torquing the clamp. Inspect the insert pocket for chips or debris before installation to ensure proper seating and edge alignment.
