BDS ZAP100 Adaptador de mandril para máquinas de furar magnéticas, haste Weldon 19mm para rosca 1/2 polegada-20 UNF

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

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.
