Boring Bar Holder | CAT50 | Orientation: Axial

This CAT40 taper boring bar holder assembly consists of a standard CAT40 taper shank body with a retention knob, a cylindrical clamping collar secured by setscrews, and a long-reach straight boring bar fitted with a single indexable carbide insert at the cutting end. The CAT40 taper interface is the industry-standard 40-taper designation compatible with a wide range of vertical machining center spindles. The assembly is configured for axial boring operations, making it suitable for applications requiring extended reach into deep bores or cavities. The boring bar is a slender rectangular-profile steel bar held in the clamp body, with the insert pocket positioned at the tip for internal turning or boring of cylindrical features. No manufacturer name, model number, or part number is visible on the item in the available photos. Confirmation of the bar diameter, boring range, maximum bore diameter, and overall projection length requires direct measurement. The insert seat accommodates a standard indexable carbide insert secured by a torx-drive clamp screw, visible in the photos. The retention knob at the base of the CAT40 shank appears to be a standard pull-stud type. This item is offered as-is from industrial surplus inventory.
