Sandvik Coromant 6078862 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 6078862 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC machining centers and turning systems. It features a 1.5-inch bore diameter and a 90mm (3.54 inches) bore depth, providing stable tool engagement for deep-bore applications. The C6 connection size integrates with compatible modular tooling systems. An internal coolant channel delivers cutting fluid directly to the cutting zone, reducing heat buildup and extending insert life. This adapter is installed by machinists and tooling specialists working in high-precision metal-removal environments.

This modular adapter suits production and job-shop environments where repeatable boring accuracy is required. The C6 interface is common in modular tooling systems used on medium-to-large CNC lathes and turning centers. With a body diameter of 2.48 inches (63mm) and a body length matching the 90mm bore depth, it fits into toolholding configurations where rigidity and concentricity are critical. Internal coolant capability makes it well-suited for steel, stainless, and difficult-to-machine alloy applications. Compatible lock screw part number 5763355 is specified for use with this adapter.
