Sandvik Coromant 6228918 Boring Bar Modular Adapter C5

Product Description

The SANDVIK COROMANT 6228918 is a boring bar modular adapter designed for use with modular tooling systems in precision machining applications. It features a 1.0000 inch bore diameter and a bore depth of 0.9843 inches (25.00 mm), along with a C5 connection size and a body diameter of 1.9685 inches (50.00 mm). The adapter incorporates an internal coolant delivery system to direct coolant directly to the cutting zone, supporting chip control and tool life in demanding boring operations. It is installed by machinists and tooling technicians on CNC lathes and turning centers where modular quick-change tooling interfaces are used.

This adapter is suited for use in machine shops and production environments running modular boring bar systems. It supports internal coolant-fed boring operations on CNC turning and boring equipment. The C5 connection size fits into corresponding C5-compatible modular toolholding systems. The lock screw size of 1.0200 inches secures the boring bar shank within the adapter body. Compatible lock screw part number 3212 010-257 is referenced in the manufacturer specifications for this adapter. The manufacturer part number on file is C5-A391.05C-25 025M.
