1/2" Keyless Drill Chuck for 8" 3/4 HP Import Buffer Polisher Motors

Convert the right-side shaft of a compatible 8-inch, 3/4 HP import buffer polisher motor into a versatile drill chuck with this Pro-Graad 1/2-inch keyless drill chuck. Designed for motors with an M16 x 2.0 threaded shaft. Compatible fit Harbor Freight Bauer, Woodskil and similar buffer/polisher motors. Always confirm the motor’s shaft size, thread pitch and rotation direction before ordering or installation. The self-tightening, keyless design provides a secure grip without requiring a separate chuck key. Its 0.08-inch to 0.51-inch (2–13 mm) clamping range accommodates drill bits and small shank-mounted accessories, including common 1/8-inch and 1/4-inch abrasive accessory shanks. It is ideal for adding versatility to compatible polishing and buffing equipment while maintaining convenient accessory changes. This chuck is intended for installation on the motor’s right side only. Disconnect the motor from its power source before installing, removing or adjusting the chuck or accessory. Inspect the chuck and accessory for wear or damage before every use, securely tighten the accessory and confirm that it rotates without interference before applying power. Never exceed the maximum rated RPM of the motor, chuck or mounted accessory; always follow the lowest applicable RPM rating. Mount only small drill bits and shank-mounted accessories in the chuck. Never use a wheel larger than four inches in diameter. Do not mount or operate any wheel or accessory that requires a safety guard. Secure the workpiece, wear appropriate eye and face protection and keep bystanders safely away during operation.
