Drill Chuck Arbor Extension | CAT50 | Orientation: Axial

Used in CNC vertical machining centers and milling machines requiring extended reach drilling capability, this CAT40 drill chuck extension assembly features a V-flange CAT40 taper shank with retention knob and a long cylindrical extension bar topped with a keyless drill chuck. The CAT40 interface is the standard 7:24 taper found on a wide range of vertical machining centers including Haas, Fadal, Mazak, and other common platforms. Two set screws are visible on the extension shank body, consistent with a setscrew-secured assembly designed for rigidity during extended-reach operations. The keyless chuck at the working end accommodates small-diameter drill bits suitable for fine hole drilling at depth. The overall assembly length is substantial, enabling access to deep features or recessed bores that standard-reach tooling cannot reach. No manufacturer markings or part numbers are visible on any surface of this assembly. The item is sold as surplus tooling and is being offered as-is with no confirmed brand, model, or capacity specifications. Buyers seeking a long-reach CAT40 drill chuck solution for deep-hole or specialty machining applications should verify fit and capacity against their specific machine and application requirements prior to purchase.
