Sumitomo 10HM038 Turning Insert DCGT32.50EFM AC530U Carbide

Product Description

The SUMITOMO 10HM038 is a solid carbide turning insert designed for precision lathe and turning center operations. Manufactured to the ANSI code DCGT32.50EFM and ISO code DCGT11T301N-SC, this insert features a 55-degree diamond shape with a positive rake geometry and a neutral hand orientation. The AC530U grade substrate is dual-coated with TiAlN and AlCrN via a PVD process under Sumitomo's Super ZX coating designation, providing wear resistance and thermal stability. The EFM chip breaker geometry controls chip flow at the cutting edge, supporting consistent surface finishes. This insert is installed by machinists and CNC turning technicians working with precision carbide tooling systems.

This insert is suited for turning applications involving stainless steel and similar secondary workpiece materials classified under ISO material group M. The screw-holding method and G tolerance code make it compatible with standard DCGT-style toolholders. Typical applications include finish turning passes where tight dimensional tolerances and controlled chip evacuation are required. The 6-degree rake angle and 7-degree relief angle support clean cutting action on difficult-to-machine alloys. The Series DC classification places it within a widely used insert family for small-to-medium diameter turning work on manual and CNC lathes.

Key Features

• Solid carbide substrate with dual PVD coating: TiAlN and AlCrN (Super ZX designation)
• 55-degree diamond insert shape with positive rake for reduced cutting forces
• EFM chip breaker geometry for controlled chip evacuation on finish turning passes
• Screw-held mounting method compatible with standard DCGT toolholders
• Meets ANSI and ISO 13399 standards for insert geometry and dimensional accuracy
• Neutral hand orientation for flexible toolholder compatibility

Compatibility

Designed for use in DCGT-style screw-clamp turning toolholders. Compatible with turning applications targeting stainless steel and ISO M-group workpiece materials. Conforms to ANSI code DCGT32.50EFM and ISO code DCGT11T301N-SC for toolholder matching.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is stopped and all stored energy is released before changing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified seating procedure. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to prevent premature edge failure.
