Flexshaft repair

I bought a used quick change handpiece for my flexshaft and the
3/32" bits keep getting stuck in it. It is a Taro, which I don’t
think exists and longer? Could anyone point me in the right direction
to someone who might be able to repair it? Thank you!

Get a pipe cleaner, spray WD40, or any oil on it. Clean out the
opening of it, then spray it directly in the hole. Use the little
straw to that comes with the wd 40. Do this every time you feel it
sticking. Clean the burs you are using before you put then in and you
will find them getting stuck less often.
