Accupro 75392688 Dcgt Turning Insert Carbide Diamond 55 Deg

Product Description

The ACCUPRO 75392688 is a DCGT-style carbide turning insert designed for precision finishing and light machining operations. It features a diamond (rhombic) 55-degree insert shape with a 7-degree relief angle and a 0.0079 inch (0.20 mm) corner radius, making it well suited for close-tolerance finishing passes. The insert carries an ACN15K manufacturer grade with a polished coating and a positive side clearance geometry. It is held in place by a screw-clamp method and is intended for use by machinists and toolroom professionals working on CNC lathes and manual turning centers.

This insert is rated for cast iron (K) and aluminum plus non-ferrous (N) workpiece materials, covering a range from high wear resistance to moderate wear resistance and toughness. The LMF+ chip breaker geometry supports light finishing cuts, with a maximum depth of cut of 0.0531 inch (1.35 mm). It is a neutral-hand insert, compatible with standard DCGT toolholders. Typical applications include finishing bores, facing operations, and external turning on non-ferrous and cast iron components in production and job-shop environments.

Compatibility

Designed as a direct-fit replacement for standard DCGT32.505 screw-clamp toolholders used in CNC and manual turning applications on cast iron and non-ferrous workpieces.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and deactivate the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified feel without over-torquing the insert pocket. Inspect the insert pocket and seating surfaces for chips or debris before seating a new insert to ensure proper alignment and edge life.
