A large flanged boring bar holder assembly marked Drill Quip on the faceplate, built for heavy-duty machine tool applications requiring a rigid, high-mass toolholding setup. The assembly consists of a substantial circular steel faceplate with four clearance bolt holes and two drive pin locators on the front face, transitioning to a long cylindrical quill or shank body, and terminating at a cartridge-style boring bar pocket with visible set screw retention at the opposite end. The faceplate configuration is consistent with a spindle nose mounting arrangement typical of horizontal boring mills, jig borers, or large machining centers. The overall construction is all-steel with significant mass, indicating this assembly was designed for stability under heavy cutting loads. The boring bar holder end features a machined cartridge pocket with set screws for securing a boring bar. No model number or part number is visible on the assembly. The specific spindle interface standard and boring bar pocket diameter have not been confirmed and require measurement prior to installation or resale. The assembly shows surface oxidation and tool room wear consistent with prior industrial use. Exact mounting compatibility should be verified by the buyer against their specific machine spindle nose configuration before purchase.
