Sumitomo 19P7BPL Turning Insert DCMT32.52ESU AC8025P Carbide

Product Description

The SUMITOMO 19P7BPL is a solid carbide coated turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. It carries the ANSI insert code DCMT32.52ESU and ISO code DCMT11T308N-SU, with an AC8025P manufacturer grade applied via CVD coating. The insert features a 55-degree diamond (rhombic) shape with a positive rake and positive side clearance, making it well-suited for finishing and light machining passes. At 0.4567 inches in length with a 3/8-inch inscribed circle and a 1/32-inch corner radius, this insert delivers consistent edge geometry and high wear resistance across steel and cast iron workpiece materials. Screw-holding retention keeps it securely seated during operation.

This insert is intended for finishing and light machining applications on steel (ISO P) and cast iron (ISO K) workpieces, where high wear resistance and controlled chip formation are priorities. The ESU chip breaker geometry is engineered specifically for finishing passes, producing predictable chip flow at light depths of cut and moderate to high cutting speeds. It is a neutral-hand insert, making it adaptable to a range of tool holders in both right- and left-hand configurations. Machinists and CNC tooling technicians in job shops, production machining, and precision component manufacturing are the primary users of this insert.

Key Features

• ANSI insert code DCMT32.52ESU with ISO equivalent DCMT11T308N-SU for broad tool holder compatibility
• AC8025P CVD-coated carbide grade with high wear resistance on steel and moderate wear resistance on cast iron
• 55-degree diamond insert shape with positive rake and positive side clearance for reduced cutting forces
• ESU chip breaker optimized for finishing and light machining operations
• Neutral hand designation fits both right- and left-hand tool holders
• Screw-holding method provides secure, repeatable seating in compatible tool holders

Compatibility

Designed as an OEM-style replacement or direct-use insert for tool holders accepting DCMT32.52 (ANSI) or DCMT11T308 (ISO) geometry inserts with screw-type clamping. Conforms to ANSI and ISO 13399 standards.

Installation Notes

This insert is installed and replaced by a machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to the tool holder manufacturer's specified torque. Inspect the insert pocket for wear or debris before seating a new insert to ensure proper contact and repeatable tool offset.
