Aloris BXA-100 Boring Bar Holder Bxa Series

Product Description

The ALORIS BXA-100 is a boring bar holder designed for use with BXA-series quick-change tool posts on engine lathes with a swing range of 10 to 15 inches. It accepts boring bars up to 3/4 inch in diameter and positions the cutting tool centerline at exactly 1 inch above the tool post reference surface. The holder stands 2 inches overall height. Built for production and toolroom environments, it is a direct-mount component that secures the boring bar rigidly to reduce chatter and maintain repeatable centerline height across tool changes. Machinists and tool and die professionals install this holder as part of a modular quick-change setup.

The BXA-100 fits lathes in the 10-to-15-inch swing class, which includes a wide range of bench and floor-model engine lathes common in job shops, maintenance facilities, and training environments. It pairs with any BXA-series tool post and wedge-style or piston-style quick-change systems that use the BXA standard. The holder is suited for internal boring, facing, and light ID turning operations where consistent tool height and bar rigidity are critical to finish quality and dimensional accuracy.

Installation Notes

Installation is performed by machinists familiar with quick-change tool post systems. Power down and disengage the lathe drive before mounting or removing any tool holder. Confirm the boring bar is fully seated and the clamping screw is torqued to the tool post manufacturer guidelines before operation. Verify centerline height against the lathe spindle centerline using a known reference before taking a first cut.
