Chuck Adaptor 19.05mm X 1/2' X 20unf Weldon Shank Tcac

Extra Information

• Ensure your chuck thread is clean and undamaged before mounting to avoid interference with the adaptor interface.
• Check that the Weldon shank mount in your machine is clean, free of debris, and properly locked to avoid vibration during use.
• Use appropriate draw-bar or locking mechanism recommended by your machine when mounting the adaptor and chuck combo.
• This adaptor is for machine tool applications; avoid high-temperature environments that may alter tempering or rigidity.

Features

• 19.05 mm (¾″) inner bore compatible with Weldon shank tooling and standard ½″ x 20 UNF thread chucks.
• ½″-20 UNF female thread allows the direct mounting of chucks with this common thread size.
• Weldon-style shank outer mount ensures a secure, rigid fit in machines designed for Weldon shank tooling.
• Precision-ground surfaces provide accurate alignment and repeatability when mounting chucks or tooling.
• Hardened alloy steel construction provides durability and maintains performance under heavy machining loads.

Benefits

• Tooling flexibility: Use your existing ½″-20 UNF chucks on machines or holders with Weldon shank mounts — no need to change all tooling.
• Improved clamping reliability: Weldon shank engagement ensures a rigid mount that supports accurate machining.
• Cost-effective upgrade: Rather than investing in entirely new chucks, this adaptor lets you reuse existing thread interface with ease.
• Reduced downtime: Quick changeover between tools and adaptation of standard chucks means less setup time on the shop floor.

Safety

• Wear appropriate eye, ear and dust protection when setting up or using machine tools.
• Ensure the machine is switched off and isolated before mounting or removing the adaptor and chuck.
• Check that the adaptor is properly seated, clamped and secured before starting machining operations.
• Do not use the adaptor if it shows signs of cracking, scoring, or wear — replace immediately to maintain accuracy and safety.
