I have two old Black and Decker Drilling Machines - One has a10mm Keyed Chuck and the other has a13mm Keyed Chuck. Both of these Chucks attach to the Drilling Machine with a Male 3/8" x 24UNF Thread. I wish to replace the old chucks with the newer Keyless Type Chucks. I have tried to purchase Keyless chucks locally but I can only find them with a 3/8" x 24UNF Female Fitting? Does anyone know where I might be able to purchase 1x 10mm and 1 x 13mm "Or" 2x 13mm Keyless Chucks with 3/8" x 24 UNF Male Fittings? Failin that; does anyone know if it is possible to purchase 3/8" x 24 UNF Male/Male Adapter? WIth Sincerity, Thanks and Best Regards, Bill Jones
SOURCE: drill chuck swap
1. Turn the screw clockwise to take it out.
2. Then you needs 3/8 allen key & insert the short side of the allen key & tighten the chuck.
3. hold the drill at the edge of the table & wack the allen key
counter clockwise & do it again as needed.
4. dewalt keyless chuck will fit but you might add a washer to insure the chuck is not rubbing the clutch collar.
5. putting it back together the other way.
