Accupro ACC-BT5 Box Turning Tool Bit 5/16 in Carbide Rh

Product Description

The ACCUPRO ACC-BT5 is a single-point box turning tool bit designed for precision lathe turning operations. Built to industry standard BT-5, it features a micrograin solid carbide tip brazed to a rigid shank, delivering consistent edge retention and fine surface finishes on turned workpieces. The right-hand cutting direction makes it compatible with conventional lathe setups. With a 5/16-inch shank width and 1-3/4-inch overall length, this compact tool bit suits small-bore and detail turning work where reach and rigidity must be balanced. It is used by machinists and tool-and-die professionals working with lathes in production and job-shop environments.

The ACC-BT5 is suited for box turning applications on manual and CNC lathes. Its micrograin carbide tip grade offers fine grain structure for improved wear resistance and edge sharpness compared to standard carbide grades, making it appropriate for finishing cuts and light to moderate stock removal on ferrous and non-ferrous materials. The compact tip dimensions — 5/16-inch tip length, 3/16-inch tip width, and 1/8-inch tip thickness — allow precise engagement in tight turning profiles. Maximum depth of cut is 5/8 inch.

Installation Notes

Installation is performed by machinists using standard tool post or tool holder setups on a lathe. Secure the shank firmly in the tool holder to the correct centerline height before engaging the workpiece. Power down and lock out the lathe spindle before seating or removing the tool bit. Inspect the carbide tip for cracks or chippage before each use, as damaged tips can fracture under cutting loads.
