Sumitomo 19RBAPG Turning Insert Wnmg AC830P Carbide

Product Description

The SUMITOMO 19RBAPG is a solid carbide turning insert in the WNMG432ESU geometry, manufactured to ANSI and ISO 13399 standards. It carries the AC830P grade designation and is CVD coated for extended wear resistance in continuous and interrupted cutting applications. The insert features an 80-degree trigon shape, a neutral hand orientation, a 0.5 inch inscribed circle, and a 1/32 inch corner radius, making it a general-purpose option for turning operations on a range of workpiece materials. Typical users are machinists and CNC lathe operators working in production or job-shop environments.

This insert is suited for turning steel and stainless steel workpieces, corresponding to ISO material groups P and M. The ESU chip breaker geometry is designed to manage chip flow across a range of depths of cut and feed rates. The AC830P grade targets applications where a balance of wear resistance and toughness is required. The insert fits into standard WNMG-style toolholders and indexing systems commonly found in production turning setups. It is sold individually but requires a minimum order of 10 pieces.

Key Features

• WNMG432ESU geometry with 80-degree trigon insert shape and neutral hand
• AC830P grade with CVD coating for wear resistance on steel and stainless workpieces
• 1/32 inch corner radius suitable for general finish and semi-finish turning
• 0 degree relief angle with negative rake, compatible with rigid WNMG clamp-and-pin toolholders
• Meets ANSI and ISO 13399 standards; ISO code WNMG080408N-SU
• Material grade classification C5, C5A, and C6

Compatibility

Designed for use in WNMG-style turning toolholders that accept a clamp and pin insert-holding method. Compatible with ISO material groups P (steel) and M (stainless steel) as primary workpiece materials, with universal secondary material applicability.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Before indexing or replacing inserts, power down the machine and confirm the spindle is fully stopped. Seat the insert fully into the toolholder pocket and secure with the appropriate clamp and pin hardware per the toolholder manufacturer specifications. Inspect the seating surface and pocket for chips or debris before clamping to ensure proper insert orientation and prevent premature edge failure.
