Aloris BXA-12 Carbide Triangular Insert Turning Holder Bxa

Product Description

The ALORIS BXA-12 is a quick-change lathe tool post holder designed for turning operations using carbide triangular inserts. It belongs to the BXA series, which is engineered for lathes with a swing range of 10 to 15 inches. The holder features a centerline height of 1 inch and an overall height of 1.75 inches, keeping insert positioning consistent and repeatable across tool changes. Compatible with TPG322 triangular inserts with a 3/8-inch inscribed circle and 1/8-inch thickness, the BXA-12 is a standard workhorse for machinists running production turning, facing, and light profiling work. Installed by machinists and toolroom technicians, it fits directly onto BXA-series quick-change tool posts.

The BXA-12 is suited for manual engine lathes and CNC-style toolroom lathes in the 10- to 15-inch swing class, covering a wide range of general-purpose turning applications. It is most commonly found in job shops, maintenance shops, and apprenticeship training environments where BXA quick-change systems are the standard setup. Typical use cases include OD turning, facing passes, and chamfering with standard TPG-style carbide triangular inserts.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with quick-change tool post systems. Before mounting or changing holders, disengage the lathe spindle and ensure the machine is fully powered down. Verify centerline height alignment with a reference tool or dial indicator before taking a cut. Secure the holder in the tool post according to the tool post manufacturer's clamping procedure to prevent movement under cutting load.
