Value Collection 950-14041 Boring Bar Holder Series Ca

Product Description

The VALUE COLLECTION 950-14041 is a Series CA Number 4 boring bar holder designed for use on engine lathes and toolroom lathes. It mounts to a quick-change tool post and positions a boring bar on center for internal turning, boring, and finishing operations. The holder accepts a 1.25-inch boring bar and includes a bushing to accommodate 1-inch bars as well. Overall height is 2.5 inches and overall length is 4.72 inches. Weighing 3.48 pounds, it is built for rigid, repeatable setups in production and job-shop environments. Installation and tool changes are handled by machinists and lathe operators.

This boring bar holder is suited for lathes with a swing of 14 to 20 inches (400 to 500 mm). It is a direct-fit Series CA component, making it compatible with CA-series quick-change tool post systems in that swing range. Typical applications include through-boring, blind-bore finishing, and internal grooving on ferrous and non-ferrous workpieces in both residential shop and light industrial settings. Through-coolant is not supported on this holder.

Installation Notes

Installation is performed by a qualified machinist or lathe operator. Power off and lock out the lathe before mounting or adjusting any tool post holder. Confirm the boring bar is clamped securely and set to the correct centerline height before taking a cut. Follow the tool post manufacturer torque guidance for clamping screws to avoid distortion of the holder body.
