The same story as the rest, Had I read their comments, I wouldn't be as they are now. This Chuck is a REAL SLAM on Makita. They need to revamp this
TOTALLY.
sucks:
This product sucks. plain and simple. I used it once and the drill bit turned loose after 10 seconds. then I tried to reinsert, but after opening it up it got stuck on open and would not close any more. at the store they said the spring probably broke. This is after one usage. Makita is overrated garbage. Stick with quality.
KEYLESS CHUCK FOR IMPACT DRILL:
Great idea but has limitations. I used it once to drill a 3/8 inch hole in wood. The drill went into impact mode when it encoutered hard wood and locked the drill bit into the chuck. I was unable to remove the drill bit since the chuck had frozen in the locked position. I wound up destroying the chuck to retrieve my drill bit. I would only recommend using this tool for small hole drilling in which case buying a set of drills with the hex shank is cheaper than buying the chuck adapter.
Must Have for Impact Drivers:
This chuck allows you to use regular drill bits in impact drivers with 1/4" hex drives. It works great and is a much better keyless chuck than the ones Dewalt puts on their drills, for instance. It could be a little smaller for the actual capacity it has. (Tool belt space is valuable!)
