Value Collection 112369209 Turning Insert TPGB322 Carbide

Product Description

The VALUE COLLECTION 112369209 is a solid carbide turning insert in the TPGB322 geometry, designed for external turning operations on CNC lathes and manual turning centers. This triangular insert features a 60-degree included angle, a 3/8-inch inscribed circle, and a 1/32-inch corner radius. The positive side clearance (11-degree relief angle) reduces cutting forces and minimizes heat buildup at the cutting edge. Grade I22 carbide provides wear resistance suitable for a range of workpiece materials. Machinists and toolroom operators select this insert for precision finishing and semi-finishing passes where dimensional accuracy and surface finish are critical.

This insert is suited for turning cast iron, non-ferrous metals, aluminum alloys, and certain superalloys, corresponding to ISO workpiece material groups K, M, N, and S. It seats into TPGB-style screw-clamp toolholders and is commonly used in production turning environments, job shops, and maintenance machining applications where a general-purpose triangular insert is required. Each insert ships individually; this product has a minimum order quantity of 10 units.

Key Features

• Solid carbide construction in material grade C2 for consistent hardness and edge retention
• TPGB insert style with positive side clearance reduces cutting forces on the workpiece
• 11-degree relief angle minimizes rubbing and extends tool life in light to medium cuts
• 1/32-inch corner radius balances edge strength with surface finish capability
• Screw-clamp holding method provides secure, repeatable insert indexing
• B-style chip breaker geometry assists chip control across compatible workpiece materials

Compatibility

Designed for use in TPGB-style screw-clamp turning toolholders that accept a 322 insert size with a 3/8-inch inscribed circle and a 0.118-inch hole diameter. Compatible with workpiece material groups K, M, N, and S per ISO classification. ANSI insert code TPGB322; ISO insert code TPGB160308.

Installation Notes

Insert seating and indexing should be performed by a qualified machinist with the machine in a locked-out, zero-energy state. Confirm the toolholder pocket is clean and free of chips or debris before seating the insert. Use the manufacturer-specified clamp screw torque range for the toolholder model in use; do not over-torque the clamp screw. Inspect the insert seating and clamping security before resuming cutting operations.
