Sandvik Coromant 5728567 Boring Bar Holder C5 Connection

Product Description

The SANDVIK COROMANT 5728567 is a boring bar holder designed for precision internal turning and boring operations on CNC lathes and machining centers. It accepts a 50 mm bore diameter with a 50.01 mm bore depth and features a C5 connection interface for secure, repeatable toolholder-to-machine coupling. The 50 mm body diameter provides rigidity during deep bore work, and the integrated internal coolant channel delivers cutting fluid directly to the tool tip, helping to evacuate chips and manage heat in tight bore profiles. Licensed machinists and CNC tooling technicians install and configure this holder as part of a modular tooling stack.

This boring bar holder is suited for medium-to-large CNC turning centers that accept C5 modular connections. Internal coolant capability makes it appropriate for steel, stainless, and other materials where chip control and thermal management are critical at the cutting zone. The no-head body style allows close-clearance boring applications where a reduced-profile holder is required. Lock screw compatibility is specified for screws 5512 063-08, enabling straightforward boring bar retention with standard tooling hardware available in most shop environments.

Installation Notes

Installation and adjustment of this holder should be performed by a qualified CNC tooling technician or machinist. Power down and lock out the machine spindle before mounting or removing the holder from the turret or tooling block. Verify that the C5 mating interface is clean and free of chips or burrs before seating the holder to ensure full contact and runout accuracy. Confirm coolant port alignment with the machine coolant supply before torquing lock screws.
