Sumitomo 19P7BPY Turning Insert DCMT32.52EMU AC8025P Carbide

Product Description

The SUMITOMO 19P7BPY is a solid carbide turning insert conforming to ANSI designation DCMT32.52EMU and ISO code DCMT11T308N-MU. It features a 55-degree diamond insert shape with a 7-degree relief angle and a neutral hand orientation, making it suitable for a wide range of turning operations. The insert is CVD-coated in the AC8025P manufacturer grade, which is engineered for cutting steel workpieces. It is held in place via a screw-clamping method and carries a positive rake geometry. Machinists and CNC turning specialists working in production or job-shop environments install this insert in compatible DCMT-style toolholders.

This insert is intended for use on steel workpieces, designated by primary workpiece material code P. The EMU chip breaker geometry supports controlled chip formation during external turning, facing, and light profiling operations. It fits standard DCMT series DC toolholders designed for 3/8-inch inscribed circle inserts. The AC8025P grade CVD coating provides wear resistance and thermal stability at elevated cutting speeds typical in steel turning applications. It is sold individually and is a non-full-radius, single-use insert not designed for regrinding.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure. Inspect the insert pocket and seating surface for chips or damage before installing a new insert.
