Aloris DA-1 Turning Facing Lathe Tool Post Holder

Product Description

The ALORIS DA-1 is a Series DA turning and facing holder designed for use on engine lathes and turret lathes with a swing range of 17 to 48 inches. It accepts tool bits ranging from 1/2 inch to 1-1/4 inches and supports a maximum cutting tool size of 1-1/4 inches. The overall height is 3-1/8 inches, the overall length is 5-7/8 inches, and the centerline height is 2-3/16 inches. Holder depth is 1 inch. At 10 pounds, the DA-1 is built for rigidity under turning and facing operations. This holder is installed and used by machinists and tool room technicians on manual lathes in production and job shop environments.

The DA-1 is suited for standard turning and facing operations across a wide range of lathe sizes, accommodating swings from 17 to 48 inches. This makes it a practical choice for both smaller bench lathes and larger floor-standing engine lathes. It does not include through-coolant capability. The Series DA designation identifies its compatibility within the ALORIS quick-change tool post system, allowing consistent tool height repeatability across holder changes without re-indicating centerline on every swap.

Installation Notes

Installation is performed by machinists or tool room technicians. Before mounting or removing any lathe holder, ensure the lathe spindle is fully stopped and the machine is locked out or powered down per shop safety procedures. Seat the holder fully in the quick-change post and tighten the locking lever to the manufacturer-recommended engagement before taking a cut. Verify tool centerline height against the lathe spindle centerline before beginning any operation.
