Ritmar
Midget Chucks are available in two series coveringa range in drill
sizes from #50 to F"or from 1/16" to 1/4" by 64ths,
in the fractional sizes.
All
Colltes and adapters are completely interchangable within each weries.
For example: int the "200" Series, an adapter having any of the
four standard thread sizes will accomodate colets holding all drill
sizes from #50 to #6, OR 1/16" TO 13/64". This versatality makes
drill diamater completely independent of thread size in the driving
spindle...it eliminates one of the big cost problems in production
tooling.
Please
Note:
Each collet holds one size of drill only.
