The Aloris DA-41D is a heavy-duty boring bar holder manufactured in the USA for the Aloris Series DA quick-change tool post system, compatible with lathes having 17 to 48-inch swing. The holder features a split-block clamping design with a knurled locking screw assembly that grips round boring bars securely, with a round bore aperture (visible in photos) sized for 1-1/4 in diameter bars — the "D" suffix in Aloris #41 series denotes this bore size. The body is constructed from hardened and black-oxide-finished steel, providing rigid, repeatable tool positioning when mounted to any Series DA (also called AXA-compatible DA) quick-change post; two socket-head cap screws on the top face secure the holder to the post's dovetail. This is a new, unused unit in original Aloris packaging (box label confirms DA-41D, Boring Bar Holder, Made in the USA, item number 79079828), with an overall height of 3-1/2 inches as specified.
