500001011 - 3/8 Inch Drill Chuck with AS-#2 Shank Adapter

Precision Drilling Components for Industrial Applications

In the realm of precision machining and industrial maintenance, the integrity of your power tool accessories is just as critical as the power tool itself. The Chuck 3/8, AS-#2 X2-1/4 is a specialized component designed to bridge the gap between your drilling machine and the cutting bit. With a 3/8-inch capacity, this chuck is versatile enough to handle the most common range of drill bit sizes used in general fabrication and repair work, from small pilot holes to larger clearance holes.

The unit features a specific AS-#2 shank configuration. In the world of tool holding, the shank is the critical interface that ensures torque is effectively transferred from the motor to the bit without slippage or wobble. The "AS" designation typically points to a specific arbor style or adapter standard, ensuring compatibility with equipment requiring this specific mount. With a length of 2-1/4 inches, this assembly is compact, minimizing the distance between the spindle bearings and the work, which can help in maintaining rigidity and accuracy during drilling operations.

Durability is paramount when selecting a chuck. This unit is engineered to withstand the rigors of daily shop use. Whether you are setting up a drill press for a production run or equipping a portable drill for on-site repairs, a reliable chuck ensures that your bits stay centered and secure. Poorly manufactured chucks can lead to "runout," where the bit spins off-center, resulting in oversized holes, broken bits, and poor surface finish. This product is designed to minimize such issues, providing a tight grip on the bit shank to prevent it from spinning inside the jaws under heavy load.

Maintenance of your chuck is also essential for longevity. Regular cleaning to remove metal chips and debris from the jaws, along with occasional lubrication of the internal mechanism, will ensure smooth operation. This 3/8" chuck is a robust solution for professionals who demand consistency and reliability in their tooling setup.
