Product Description

?

This keyed chuck has a 1/2 inch capacity with a 5/8 inch - 16 thread. Use with chuck key 48-66-3280 and key holder 48-66-4040. The metal construction provides heavy-duty durability while the keyed design ensures the bit retention needed for high-torque applications. It can be used on reversing drills of matching capacities and threaded spindles. If your drill's bit retention is suffering, the rotation feels stiff, or the chuck has seized up entirely, a new chuck should fix the problem.

Milwaukee Hole Hawg, 413B. Removed the chuck along with the screw in the center. It\'s reversed threads, tightened up a 3/8 allen wrench in the chuck & hit it with my dead blow hammer. Carefully remove the rear cover, be careful because you need to lift it off and wiggle it evenly straight up. If one of the gears doesn\'t let loose fr om the cover just stick your finger in & push down on the gear and pull straight up on the cover until it breaks loose. There\'s a certain order that everything comes out. Print out the parts sheet so you know what to expect and lay everything out. I carefully cleaned up the parts, removed old grease inside & clean out with solvent.
