Accupro 75542555 DCMT32.51 Carbide Turning Insert

Product Description

The ACCUPRO 75542555 is a DCMT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. It features a 55-degree diamond (rhombic) insert shape with a 7-degree relief angle and a PVD coating applied over a carbide substrate in the ACM25P grade. The corner radius measures 0.40 mm (0.0157 inches), making it suited for finishing and semi-finishing passes where tight tolerances and surface finish quality are priorities. With two usable cutting edges and a positive side clearance geometry, this insert delivers efficient chip evacuation and extended tool life across a range of workpiece materials.

This insert is intended for turning applications on steel, stainless steel, and special or super alloys. The ACM25P grade with WSF+ chip breaker geometry balances wear resistance and toughness to handle varying cutting conditions from stable finishing cuts to moderately interrupted passes. It is commonly used in production machining environments, job shops, and maintenance-repair operations where consistent dimensional accuracy is required. The screw-clamping holding method provides secure seating in compatible DCMT insert pockets.

Key Features

• DCMT insert style with 55-degree diamond shape for versatile turning geometry
• ACM25P carbide grade with PVD coating for high wear resistance across steel and stainless steel
• WSF+ chip breaker design promotes controlled chip formation and evacuation
• Positive side clearance reduces cutting forces and heat buildup at the cutting edge
• Two cutting edges per insert for extended service before replacement
• Screw-mount holding method ensures repeatable insert indexing and secure clamping

Compatibility

Designed as a direct-fit replacement for toolholders accepting DCMT32.51 (ANSI) or DCMT11T304 (ISO) inserts with a screw-clamp holding method and positive clearance pocket geometry.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician. Always power down and lock out the machine spindle before removing or seating inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer to avoid cracking the carbide substrate. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
