Sumitomo 19HMBPF Turning Insert CCMT32.52ESU AC530U Carbide

Product Description

The SUMITOMO 19HMBPF is a solid carbide turning insert in the CCMT32.52ESU geometry, coated with TiAlN and AlCrN via a PVD process under the proprietary Super ZX coating designation. This insert features an 80-degree diamond shape, a positive rake angle of 8 degrees, and a 7-degree relief angle, making it well suited for precision external turning operations. The ESU chip breaker geometry promotes efficient chip control during cutting. At 0.3819 inches in length with a 3/8-inch inscribed circle and a 1/32-inch corner radius, this insert is designed for consistent, repeatable performance in demanding machining environments. It is installed by machinists and CNC operators on turning centers and lathes.

This insert is intended for turning applications where tight tolerances and surface finish quality are required. The AC530U grade with TiAlN and AlCrN coating makes it particularly effective when machining stainless steel and similar difficult-to-cut materials classified under ISO workpiece material code M. The neutral hand orientation and screw-holding method make it compatible with standard CCMT-style toolholders. It fits residential and commercial machine shop environments as well as production floor turning operations.

• 7-degree relief angle and clearance code C for reduced flank wear
• Screw-holding method ensures secure seating in CCMT-compatible toolholders
• Meets ANSI and ISO 13399 standards; ISO code CCMT09T308N-SU

Compatibility

Designed for use in CCMT-style screw-on toolholders. Recommended for machining stainless steel and ISO M-category workpiece materials. ANSI code CCMT32.52ESU; ISO code CCMT09T308N-SU.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to seat the insert screw to the toolholder manufacturer's specified torque. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to ensure proper contact and edge alignment.
