Aloris 4-BS Ca Series Tool Post Holder Set 5 Pc

Product Description

The ALORIS 4-BS is a five-piece CA Series tool post holder set designed for engine lathes with a swing range of 14 to 20 inches. The set includes a tool post and four dedicated holders covering the most common turning, boring, facing, and parting operations. Built around the CA Series quick-change system, each holder indexes repeatably to the tool post without re-indicating between tool changes. The 7/8-inch bolt hole diameter matches standard CA Series tool post mounting. At 39 pounds, the set has the mass expected of production-grade lathe tooling. Machinists and tool room technicians working on mid-size manual lathes will find this set covers the majority of daily operations.

This set is suited for machine shops, maintenance departments, and vocational training environments running mid-size manual engine lathes in the 14 to 20-inch swing class. The CA Series is a wedge-type quick-change system, making the set appropriate for production turning applications where frequent tool changes are required. All five pieces ship together as a single kit, allowing a lathe to be set up from scratch without sourcing holders individually.

Installation Notes

Installation is performed by a machinist or tool room technician familiar with manual lathe setup. Power down and lock out the lathe spindle drive before mounting or adjusting any tool post or holder. Ensure the tool post stud and nut are tightened to the lathe compound rest per the lathe manufacturer's specification before taking cuts. Verify holder height alignment with the spindle centerline using a test indicator before beginning any operation.
