Accupro 75515791 Turning Insert DCMT32.51 Cvd Carbide

Product Description

The ACCUPRO 75515791 is a DCMT-style carbide turning insert designed for precision metal turning operations on CNC and manual lathes. It carries ANSI code DCMT32.51 and ISO code DCMT11T304, with a 55-degree diamond (rhombic) insert shape and a 7-degree relief angle providing positive side clearance. The insert is manufactured in grade ACM20P with a CVD coating and features the WM+ chip breaker geometry. It is intended for machinists and toolroom technicians running steel and stainless steel applications where high wear resistance to moderate toughness is required.

This insert is suited for finishing and semi-finishing passes on steel (P) and stainless steel (M) workpieces. The neutral hand orientation makes it adaptable across a range of toolholders accepting DCMT-style inserts. The screw-type insert holding method ensures secure clamping during interrupted or continuous cuts. Typical applications include shaft turning, facing, and profile work on CNC turning centers and manual engine lathes in production and job-shop environments.

Key Features

• DCMT diamond insert shape with 55-degree included angle for versatile turning profiles
• CVD coating in grade ACM20P for high wear resistance on steel and stainless steel
• WM+ chip breaker geometry for effective chip control in steel and stainless steel cuts
• Positive side clearance (7-degree relief angle) reduces cutting forces
• 2 cutting edges per insert maximize usable insert life
• Screw-type holding method for secure, repeatable seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement turning insert for DCMT-style screw-on toolholders accepting ANSI code DCMT32.51 or ISO code DCMT11T304 inserts.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure machine power and spindle lockout before changing inserts. Seat the insert fully against the toolholder pocket and tighten the clamping screw to the toolholder manufacturer specification using the appropriate torx or hex key. Inspect the insert seat and clamp screw condition each time an insert is indexed or replaced.
