Sandvik Coromant 5726332 Boring Grooving Bar Holder

Product Description

The SANDVIK COROMANT 5726332 is a boring and grooving bar holder designed for precision internal machining operations. Built for the CoroTurn XS series, this holder accepts tooling with a 4mm inside diameter and features a 1-inch (25mm) outside diameter body with a 25.4mm head diameter. The overall length is 150mm (approximately 5.906 inches). Through-coolant capability is integrated directly into the holder, allowing cutting fluid to be delivered close to the cutting edge for improved chip evacuation and tool life. This holder is intended for use by machinists and toolroom professionals working on CNC lathes and turning centers.

This holder suits small-diameter internal grooving and boring applications where tight tolerances and reliable coolant delivery are required. Its compact geometry makes it well suited for Swiss-style turning centers, gang-tool lathes, and small-part turning operations. The CoroTurn XS platform is engineered for watchmaking, medical component, and precision parts industries where bore diameters in the sub-10mm range are common. Installation is performed by qualified machinists following machine tool manufacturer guidelines.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine must be powered down and all axes secured before mounting or removing toolholders. Confirm that the turret or toolpost bore diameter matches the 1-inch outside diameter of this holder and that the machine tool coolant system pressure is within the range supported by the CoroTurn XS platform. Follow SANDVIK COROMANT assembly instructions for torque and insert seating procedures specific to this series.
