Aloris 5-BS Tool Post Holder Set 17-48 Inch Lathe

Product Description

The ALORIS #5-BS is a five-piece Series DA tool post holder set designed for lathes with a swing range of 17 to 48 inches. The set provides a complete foundation for general turning, facing, boring, and parting operations on mid-to-large engine and toolroom lathes. It ships with a tool post and four matched holders, each engineered to the DA series standard for quick indexing and repeatable tool height. The bolt hole diameter is 1 inch. At 81 pounds, the set is built for rigid, heavy-duty shop use. Installation and setup are handled by machinists and tool and die professionals.

This set is suited to production and job-shop environments running lathes in the 17 to 48 inch swing class. The included holder styles cover the most common lathe operations: turning and facing with the Style 1 holder, combined boring, turning, and facing with the Style 2 holder, heavy-duty boring bar work with the Style 4D holder, and parting and grooving with the Style 7 universal parting blade holder. The DA series quick-change design allows holder swaps without resetting tool centerline height, reducing setup time between operations.

Installation Notes

Installation is performed by a qualified machinist. Power down and fully lock out the lathe before mounting or removing the tool post or any holder. Secure the tool post to the compound rest using the appropriate 1-inch bolt and torque to the lathe manufacturer specification. Verify tool centerline height with a reference bar before beginning cuts, and confirm all holder locking mechanisms are fully engaged prior to operation.
