Accupro 75357590 Turning Insert DCMT32.51 Carbide

Product Description

The ACCUPRO 75357590 is a DCMT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. It features a diamond (rhombic) 55-degree insert shape with a 7-degree relief angle and a neutral hand orientation, making it suitable for both left- and right-hand toolholders. The inscribed circle measures 0.3752 inches (9.53 mm) and the insert thickness is 0.1563 inches (3.97 mm). The uncoated ATP15M carbide grade delivers high wear resistance across steel, stainless steel, and cast iron workpiece materials. A screw-clamp holding method secures the insert in compatible toolholders.

This insert is used in finish to semi-finish turning applications on steel (P-class), stainless steel (M-class), and cast iron (K-class) materials. It is well suited for residential and commercial machine shops, job shops, and production turning environments. The EN-JF chip breaker geometry supports controlled chip evacuation at moderate to high cutting speeds. Maximum depth of cut is 0.0531 inches (1.35 mm), positioning this insert for light to medium material removal passes rather than heavy roughing work.

Key Features

• DCMT diamond 55-degree insert shape with positive side clearance for reduced cutting forces
• Uncoated ATP15M carbide grade rated for high wear resistance on steel, stainless steel, and cast iron
• Neutral hand orientation fits both left- and right-hand DCMT-compatible toolholders
• EN-JF chip breaker promotes chip control during finish and semi-finish turning
• Screw-clamp insert holding method for secure, repeatable seating
• Two cutting edges per insert for extended tool life per unit

Compatibility

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

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket before tightening the clamp screw to the toolholder manufacturer specification. Inspect the pocket and clamp screw for wear or damage before installing a new insert to ensure proper seating and safe cutting performance.
