BDS ZAP100 Drill Chuck Adapter for Magnetic Drilling Machines, 19mm Weldon Shank to 1/2 inch-20 UNF Thread

This precision-ground drill chuck adapter converts the 19 mm Weldon shank of BDS magnetic drilling machines to a 1/2"-20 UNF threaded spindle, allowing standard drill chucks to be mounted securely. Ideal for expanding the versatility of your magnetic drill in industrial drilling applications.

Advantages

Manufactured from hardened steel with a precision ground finish, this adapter ensures a rigid, concentric connection between the machine spindle and the drill chuck. The right-hand UNF thread provides a secure, vibration-resistant mount, while the 19 mm Weldon shank with flat guarantees positive torque transmission and prevents slippage under load.

Suitable for

• BDS magnetic drilling machines with 19 mm Weldon spindle
• Drill chucks with 1/2"-20 UNF internal thread
• Industrial drilling, metalworking, and fabrication tasks

Key specifications

Recommendations

For best results, ensure the Weldon shank is fully seated and the set screw tightened against the flat. Use only chucks with matching 1/2"-20 UNF threads to avoid damage. Regularly inspect the adapter for wear or deformation in demanding production environments.
