Modified Drill Bits Fit Worn Chucks

Modified Drill Bits Fit Worn Chucks FARM SHOP Miscellaneous 33-3-37 If your drill bits are slipping in the chuck, your chuck may be worn. To solve the problem, Joe Gibbs came up with a way to modify bit heads to give the worn chuck something to grip. "As a chuck ages, it's hard for it to hold a bit when it hits resistance," says Gibbs. "I found out that it helps to grind flat faces on the drill bit ends." To get three even faces, Gibbs has come up with a simple jig. He cuts a triangle with 4-in. sides from a piece of 2-in. thick scrap wood. An old chuck is then mounted in the triangle's center and an emery wheel mounted on Gibbs' drill press. "I mount the drill bit with the cutting end in the chuck and slide it against an emery wheel on my drill press," explains Gibbs. "When I have a slight face on one side, I just turn the wood block to the next side and slide it back to the emery wheel."
