Aloris DA Quick Change Tool Post 17-48 in Lathe Swing

Product Description

The ALORIS DA is a wedge-type quick change tool post designed for engine lathes with a swing range of 17 to 48 inches. It mounts to the compound rest and allows the operator to swap toolholders rapidly without losing position, with a repeatability of 0.0001 inches. The tool post stands 8.75 inches overall, with a tool post height of 7.625 inches and a centerline height range of 2.6875 to 3.6875 inches. The wedge-locking mechanism indexes to 24 positions around the post. This Series DA unit is installed by machinists and toolroom technicians on mid- to large-bore manual lathes.

The DA series tool post is suited for production and job-shop environments where frequent tool changes are required without sacrificing rigidity or repeatability. The 24-position indexing and wedge-lock design keep toolholders firmly seated during turning, facing, boring, and threading operations. The 1-inch bolt hole diameter accommodates standard compound rest stud configurations found on a wide range of industrial engine lathes in the 17-to-48-inch swing class. A mounting wrench is included to secure the post at installation.
