Accupro 75261073 Ccmt Turning Insert Cvd Carbide

Product Description

The ACCUPRO 75261073 is a CCMT-style carbide turning insert designed for precision external and internal turning operations on CNC and manual lathes. It features an 80-degree diamond (rhombic) insert shape, a CVD coating applied over a carbide substrate, and a neutral hand orientation. The ACM20P manufacturer grade targets steel (P) and stainless steel (M) workpiece materials, delivering high wear-resistance to moderate wear-resistance with balanced toughness. The insert mounts via screw-holding method and carries a positive side clearance with a 7-degree relief angle. The WSF+ chip breaker geometry supports controlled chip evacuation in finishing and light roughing passes.

This insert is suited for turning applications on steel and stainless steel components in production machining environments. It fits toolholders designed for CCMT21.50.5 (ANSI) or CCMT060202 (ISO) insert pockets. Typical applications include shaft turning, facing, and contour work where tight tolerances and surface finish are required. The 0.20 mm corner radius makes it well suited for finishing passes and profiling operations where a fine nose radius is needed to achieve low surface roughness values.

Key Features

• CVD-coated ACM20P carbide grade for steel and stainless steel workpieces
• 80-degree diamond insert shape provides a strong cutting edge with good clearance for profiling
• WSF+ chip breaker geometry supports controlled chip formation in finishing and semi-finishing cuts
• Positive side clearance reduces cutting forces and improves surface finish
• Screw-clamp holding method ensures rigid, repeatable insert positioning in the pocket
• 2 usable cutting edges per insert

Compatibility

Designed to seat in toolholders and boring bars with CCMT21.50.5 (ANSI) or CCMT060202 (ISO) insert pockets. Confirm pocket geometry, clamp style, and screw thread before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque — do not over-tighten, as carbide inserts are brittle and can crack under excessive clamp load. Inspect the insert pocket and clamp for wear or debris before seating a new insert.
