Aloris DA-141 Boring Bar Holder 2 Inch Series Da

Product Description

The ALORIS DA-141 is a boring bar holder designed for use with the Series DA quick-change tool post system on engine lathes. It accepts a 2-inch boring bar and features a centerline height of 1.75 inches with an overall height of 3.5 inches. Rated for lathes with a swing range of 17 to 48 inches, this holder covers a broad range of mid-size and larger engine lathes found in production and job-shop environments. At 7 pounds, the DA-141 is a solid, rigid holder built to minimize chatter and maintain accurate tool positioning during internal turning and boring operations. Machinists and toolroom technicians install this holder as part of a quick-change setup to reduce tool changeover time while maintaining repeatable centerline height.

The DA-141 is suited for internal boring operations on engine lathes in both production machining and toolroom settings. It is compatible with lathes having a swing between 17 and 48 inches, making it appropriate for a wide range of manual and CNC-assisted engine lathe configurations. The Series DA designation indicates compatibility with ALORIS DA-series quick-change tool posts. Through-coolant is not supported on this holder. Typical applications include roughing and finishing bores in metal workpieces where a 2-inch boring bar is the appropriate tooling selection.
