Sumitomo 192RBPY Turning Insert DCMT32.52EMU AC415K Carbide

Product Description

The SUMITOMO 192RBPY is a solid carbide turning insert designed for precision external and internal turning operations on CNC and manual lathes. Manufactured to ANSI code DCMT32.52EMU and ISO code DCMT11T308N-MU, this insert features a 55-degree diamond shape with a neutral rake and a 7-degree relief angle. The AC415K grade uses a CVD coating process with the FF proprietary coating designation, making it well suited for cutting cast iron and other K-category workpiece materials. The EMU chip breaker geometry promotes controlled chip evacuation and stable cutting performance across a range of feed rates and depths of cut.

This insert is intended for use in screw-held toolholders that accept DCMT-style inserts. It is commonly used in production turning environments where dimensional consistency and insert-to-insert repeatability are required. The AC415K grade targets cast iron as a primary workpiece material, with secondary K-material applications also supported. The neutral hand orientation makes it adaptable to both right-hand and left-hand holder configurations without changing insert style. Typical users include CNC machinists, tool-room operators, and precision manufacturing shops.

Key Features

• CVD-coated solid carbide construction with AC415K grade for extended tool life in cast iron applications
• 55-degree diamond insert shape (DCMT) with 7-degree relief angle for positive clearance geometry
• EMU chip breaker promotes controlled chip formation across typical turning parameters
• Neutral rake and neutral hand orientation for flexible holder compatibility
• Screw-held mounting method provides secure clamping and repeatable insert indexing
• Conforms to ANSI and ISO 13399 standards for interchangeability and tooling data integration

Compatibility

Designed for use in screw-clamp toolholders accepting DCMT-style inserts per ANSI code DCMT32.52EMU and ISO code DCMT11T308N-MU. Optimized for cast iron and K-category workpiece materials.

Installation Notes

This insert is installed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer when securing the clamping screw. Inspect the toolholder pocket and seating surface for damage or debris before seating the insert to ensure proper contact and runout control.
