Chuck adapter BRÜDER MANNESMANN M12490

The BRÜDER MANNESMANN M12490 chuck adapter is designed to expand the compatibility of handheld and bench drills with chucks accommodating 1.5–10 mm drill bits. Finished in black, the adapter features a 90° point angle to match the seating geometry of common drill bits and provides a stable connection between the drill spindle and the chuck. Constructed for regular workshop and home use, the adapter supports quick bit changes and consistent centring during drilling operations.

Advantages

How to use

Fit the adapter firmly to the drill spindle according to the drill manufacturer's instructions, ensuring correct alignment of the seating surfaces. Mount the drill chuck onto the adapter and tighten securely using the appropriate method for the chuck type (keyed or keyless). Insert the desired drill bit into the chuck, centre it properly and tighten to prevent slippage. Verify runout and secure fit before starting the drilling operation, and always follow safe operating speeds for the material being drilled.

Recommendations

Regularly inspect the adapter and chuck for wear or damage. Keep contact surfaces clean and lightly lubricated if recommended by tool manufacturer guidelines. Use the adapter within the specified chuck capacity (1.5–10 mm) and avoid excessive torque or impact loads that exceed the adapter's intended application.
