Sumitomo 19R5334 Turning Insert CNMG431EGU AC6020M Carbide

Product Description

The SUMITOMO 19R5334 is a solid carbide turning insert in the CNMG431EGU configuration, coated with Sumitomo's Absotech Platinum finish applied via CVD process. Designed for negative-rake turning operations, this insert carries the AC6020M manufacturer grade and is engineered primarily for machining stainless steel. It features an 80-degree diamond insert shape, a neutral cutting direction, and an EGU chip breaker geometry. At 0.5079 inches in length with a 1/2-inch inscribed circle and a 1/64-inch corner radius, it fits standard CNMG toolholders using pin and screw holding methods. Machinists and tooling specialists working in production turning environments install these inserts.

This insert is rated for Material Grade M20 and is classified under Primary Workpiece Material Code M, indicating suitability for austenitic and ferritic stainless steels. The EGU chip breaker geometry supports stable chip control during continuous and interrupted cuts on difficult-to-machine materials. The CVD-applied Absotech Platinum coating provides wear resistance and thermal stability at elevated cutting speeds. It conforms to ANSI code CNMG431EGU and ISO code CNMG120404N-GU, meeting both ANSI and ISO 13399 standards, making it compatible with toolholder systems dimensioned to either standard. The CN series designation applies. This insert is sold individually but requires a minimum order quantity of 10 units.

Key Features

• Absotech Platinum CVD coating for wear resistance and thermal stability on stainless steel
• AC6020M grade with EGU chip breaker geometry for controlled chip evacuation
• 80-degree diamond insert shape (Shape Code C) with neutral cutting direction
• 1/64-inch corner radius and 1/2-inch inscribed circle in CNMG431EGU form factor
• Pin and screw holding method compatible with standard CNMG toolholder systems
• Conforms to ANSI and ISO 13399 standards; dual-coded CNMG431EGU and CNMG120404N-GU

Compatibility

Designed for use in standard CNMG toolholders using pin and screw clamping. ANSI code CNMG431EGU and ISO code CNMG120404N-GU confirm dimensional interchangeability with toolholder systems dimensioned to either standard. Primary application is stainless steel turning at Material Grade M20.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and spindle locked before changing inserts. Seat the insert fully against the toolholder pocket before tightening the clamping screw or pin to avoid seating errors that affect runout. Inspect the insert pocket and clamp for wear or damage each time inserts are indexed or replaced. Follow the machine tool manufacturer's torque specifications for the clamping hardware.
