Accupro 75210278 Ci Grooving Insert 3mm ACP45M Pvd

Product Description

The ACCUPRO 75210278 is a CI-style grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. It carries a cutting width of 0.1181 inches (3.000 mm) and a corner radius of 0.0079 inches (0.20 mm), making it suitable for tight-tolerance groove profiles. The insert is manufactured in grade ACP45M with a PVD coating applied to enhance wear resistance and edge life across a range of workpiece materials. A positive rake geometry reduces cutting forces and heat generation at the tool tip. Machinists and toolroom technicians install this insert as a consumable replacement in compatible CI-style grooving toolholders.

This insert is intended for grooving, parting, and recessing applications on metalworking lathes operating under moderate to heavy cutting conditions. The CI series geometry and GPP chip breaker promote reliable chip control in both interrupted and continuous cuts. It is suited for production turning environments where consistent groove width and surface finish are required across high part volumes. The positive rake and PVD finish make it a practical choice for steel, stainless, and similar materials where tool life and edge stability matter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians on powered-off, locked-out turning equipment. Confirm the toolholder clamping method matches the insert holding style before seating the insert. Inspect the insert pocket and clamping surfaces for debris or damage prior to installation. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for this insert size.
