Drill chuck King Tony 39124012M, keyed metal chuck for power drills and drill presses

King Tony 39124012M is a keyed metal drill chuck designed for use with power drills and drill presses. The chuck provides secure clamping of round- and hex-shank bits using a dedicated key, delivering positive torque transfer and stable drilling performance for general-purpose metalworking and workshop tasks where a keyed chuck is preferred.

Advantages

The metal construction ensures durability and resistance to wear under repetitive tightening. The keyed tightening mechanism allows higher clamping force than many keyless designs, reducing bit slip during high-torque applications. Compatibility with standard drill keys and common drill spindles makes mounting and bit changes straightforward in workshop environments.

Suitable for

• Drilling with corded or cordless power drills
• Use on drill presses for bench drilling tasks
• Holding tap drills for thread preparation in metalworking
• Applications requiring firm bit retention under torque

Key specifications

• Type: keyed metal drill chuck suitable for power drills and drill presses
• Operation: keyed tightening and release for secure bit clamping
• Compatibility: designed for standard round- and hex-shank drill and tap bits
• Intended use: general-purpose drilling and metalworking screw thread preparation

How to use

Mount the chuck to the drill spindle or press arbor according to the drill manufacturer’s instructions, ensuring a secure fit. Insert the desired drill or tap bit into the jaws, position it to the required depth, then use the matching chuck key to tighten the jaws evenly until the bit is firmly clamped. Before operation, verify alignment and secure mounting; after use, loosen the key to remove or change the bit.

Usage recommendations

Use the appropriate-sized key and apply steady, even torque when tightening to avoid uneven jaw grip. For threaded hole preparation in metal, select a tap drill of the correct size and ensure the chuck holds the tap securely to prevent slippage. Periodically clean and lightly lubricate the chuck jaws and key interface to maintain smooth operation.
