Kennametal 1832321 Turning Insert DNMG433MP KC5010 Carbide

Product Description

The KENNAMETAL 1832321 is a solid carbide turning insert in the DNMG433MP geometry, coated with TiAlN via a PVD process and graded KC5010. It carries a 55-degree diamond (rhombic) shape with a 0.5-inch inscribed circle, a 3/64-inch corner radius, and a neutral hand orientation. The MP chip breaker is engineered for roughing to medium machining operations. Negative rake and negative side clearance geometry supports stable, controlled cutting in demanding applications. This insert is handled by licensed machinists and CNC tooling technicians on lathes and turning centers.

The 1832321 is suited for turning, facing, boring, back turning, and back boring operations. Its KC5010 grade targets steel, stainless steel, cast iron, and superalloys and titanium, offering high wear resistance to moderate wear resistance and toughness across those material groups. The KENLOC series design supports both clamp and pin holding methods, making it compatible with standard DNMG-style toolholders used in production and job-shop environments handling a wide range of part geometries and material conditions.

Key Features

• KC5010 PVD TiAlN coating delivers high wear resistance across steel, stainless steel, cast iron, and superalloy workpieces
• 55-degree diamond insert shape provides two acute cutting corners per edge side, well suited for profiling and contouring passes
• MP chip breaker geometry supports both roughing and medium machining chip control
• 4 cutting edges per insert reduce tooling cost per edge in production runs
• Negative rake and chamfered-honed cutting edge style improves edge strength and reduces chipping risk on interrupted cuts
• Compatible with clamp and pin holding methods for flexible toolholder integration

Compatibility

Designed for use in DNMG-style toolholders conforming to ANSI insert code DNMG433 and ISO insert code DNMG150412. Suits standard KENLOC-series tooling setups using clamp or pin insert retention. Verify toolholder pocket geometry and insert seating before use.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Seat the insert firmly in the toolholder pocket and engage the clamping mechanism or retaining pin before resuming any cutting operation. Follow the toolholder manufacturer's recommended clamping procedure and inspect the insert seat for chips or debris that could affect seating accuracy.
