Sumitomo 19RB367 Turning Insert DNMG432EUP AC830P Carbide

Product Description

The SUMITOMO 19RB367 is a solid carbide coated turning insert in the DNMG432EUP geometry with manufacturer grade AC830P. It carries a 55-degree diamond shape (Insert Shape Code D), a neutral hand orientation, and a negative rake angle. The CVD coating process delivers a hard, wear-resistant surface suited for interrupted and continuous cuts. The EUP chip breaker geometry controls chip flow across a range of cutting depths and feeds. This insert is used by machinists and CNC turning specialists working in production and job-shop environments.

The 19RB367 is designed for turning applications on steel and stainless steel workpiece materials, consistent with primary workpiece material designations M and P. The EUP chip breaker makes it a practical choice for medium to finishing passes where chip control and surface finish consistency matter. It fits standard DNMG-style insert pockets and is compatible with clamp and pin holding methods, making it straightforward to seat in existing toolholders already configured for DNMG geometry inserts.

Key Features

• CVD-coated solid carbide construction in manufacturer grade AC830P for extended tool life on steel and stainless
• 55-degree diamond insert shape (DNMG) with neutral hand for flexible toolholder compatibility
• EUP chip breaker geometry promotes consistent chip control on medium to finishing cuts
• Negative rake angle reduces cutting edge chipping risk during interrupted cuts
• Clamp and pin holding method for secure, repeatable seating in DNMG toolholders
• Meets ANSI and ISO 13399 standards; ISO code DNMG150408N-UP

Compatibility

Designed as an OEM-style replacement or direct-fit insert for DNMG-style turning toolholders that accept clamp and pin holding methods with a 0.5000-inch inscribed circle. Primary workpiece material designations are M and P, covering stainless steel and carbon and alloy steels. Material grades C5, C5A, and C6 apply.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Always power down and lock out the machine spindle before changing inserts. Seat the insert fully into the pocket and confirm the clamp and pin are torqued per the toolholder manufacturer's specifications. Inspect the pocket for chips or debris before seating a new insert to avoid seating errors that cause premature edge failure.
