Mike Dibble, The Jump Ringer blade arbor’s shaft is .155" diameter.
Rio shows an accessory collet set for your #44T handpiece (2003
catalog, page 134, item E) which includes a 5/32 (.156") collet.
This will probably fit. Since I do not have a 44T handpiece, I can’t
answer the following:
Does the body of your hand piece have a 1.000" diameter?
Does the tapered section of your handpiece start less than 1"
form the end of the collet? If the answer to both questions is yes,
it will work with the 5/32" collet. If either answer is no, you will
need to use a #30 handpiece. Because your Model H system accepts
only the 44T hand piece, you will need a new flexshaft system. We
recommend the Model S.
Let me know if I can be of further help.
