Sumitomo 19HV366 Turning Insert DNMG431 AC510U Carbide

Product Description

The SUMITOMO 19HV366 is a solid carbide turning insert designed for demanding metal-cutting operations on superalloys and special alloy workpieces. This insert carries the ANSI designation DNMG431EUP and ISO code DNMG150404N-UP. It features a PVD-applied dual-layer TiAlN and AlCrN coating marketed under Sumitomo's Super ZX designation, which delivers high wear resistance at the cutting edge. The 55-degree diamond (rhombic) shape, combined with a positive rake angle of 10 degrees and a neutral hand orientation, suits a range of turning setups. A corner radius of 0.0156 inches and an inscribed circle of 0.5 inches define the cutting geometry. Licensed HVAC and machining-trade professionals specify this insert for roughing and medium machining passes.

This insert is engineered for primary use on superalloy and special alloy materials, classified under workpiece material code S. The EUP chip breaker geometry is suited for roughing and medium machining operations where chip control and edge integrity are critical. It mounts via clamp or pin holding methods and carries a negative side clearance with tolerance code M. Applications include CNC turning centers and manual lathes where consistent performance on difficult-to-machine materials is required. The insert is sold individually but is subject to a minimum order quantity of 10 units per order.

Installation Notes

This insert is installed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the tool holder pocket before tightening the clamp or pin to avoid edge chipping. Inspect the pocket seat and clamp for wear or debris prior to each insert change.
