Accupro 75560425 Dcgt Carbide Turning Insert 55 Degree

Product Description

The ACCUPRO 75560425 is a DCGT-style carbide turning insert designed for precision metal cutting on CNC and manual lathes. Built to ANSI code DCGT21.50.5 and ISO code DCGT070202, this insert features a 55-degree diamond (rhombic) shape with a 7-degree relief angle and a sharp 0.0079-inch (0.20 mm) corner radius. The PVD-coated ACM15S carbide grade delivers high wear resistance with moderate toughness, making it well suited for finishing and semi-finishing passes. It is installed by machinists and CNC operators in production and job-shop environments.

This insert is engineered for cutting stainless steel (ISO material group M) and special and super alloys (ISO material group S). The LMF+ chip breaker geometry promotes controlled chip flow at lower cutting depths, making it a practical choice for tight-tolerance finishing operations. The neutral hand orientation allows use on standard DCGT-compatible toolholders without directional restriction. Maximum depth of cut is 0.0531 inches (1.35 mm), placing this insert in light to medium finishing applications rather than heavy roughing.

Key Features

• ANSI code DCGT21.50.5 and ISO code DCGT070202 for straightforward toolholder matching
• ACM15S PVD-coated carbide grade with high wear resistance rated for stainless steel and super alloys
• 55-degree diamond insert shape (shape code D) with positive side clearance for reduced cutting forces
• LMF+ chip breaker geometry optimized for light finishing cuts on difficult materials
• Screw-lock insert holding method for secure, repeatable seating in the toolholder pocket
• 2 cutting edges per insert for extended service life before replacement

Compatibility

Designed as an OEM-style replacement turning insert for DCGT-compatible toolholders accepting a 0.2500-inch inscribed circle, 0.0937-inch thick, screw-clamped inserts with a 0.1126-inch hole diameter. Confirm toolholder pocket tolerance and clearance codes before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the toolholder is clear of the work zone before indexing or replacing inserts. Use the correct torque driver for the clamping screw to avoid pocket damage — follow the toolholder manufacturer's seating procedure. Inspect the pocket seat and screw threads for chips or wear before installing a new insert.
