Sandvik Coromant 6228916 Boring Bar Modular Adapter 0.75 in

Product Description

The SANDVIK COROMANT 6228916 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC machining centers and turning systems. It accepts a 0.75-inch bore diameter and features an internal coolant delivery channel that directs fluid directly to the cutting zone, reducing heat buildup and extending insert life. The adapter uses a C4 connection size and a lock screw with a 1.02-inch seating diameter for secure, repeatable tool engagement. The body diameter measures 1.5748 inches with a body length of 0.9843 inches. This component is installed by machinists and tooling specialists setting up modular boring systems for high-tolerance internal machining work.

This adapter fits into modular quick-change tooling systems that use a C4 interface, common in production turning cells and machining centers requiring frequent tool changes without sacrificing rigidity or runout accuracy. The internal coolant port supports high-pressure coolant delivery, making it suitable for deep-bore finishing operations, difficult-to-machine alloys, and applications where chip evacuation is critical. Bore depth capacity is 0.9843 inches. It is well-suited for both horizontal and vertical machining center setups where modular tooling reduces changeover time.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or removing any modular tooling adapter. Verify that the lock screw is seated properly and that the C4 connection interface is free of chips or debris before torquing. Confirm internal coolant passages are clear and aligned with the machine coolant supply port prior to operation.
