Jiffy Tap Chucks

All chucks attach to the same size #4 Jacobs male taper using a standard 808 Woodruff key and can be secured with a standard 1/4"-20 x 3/4 socket head cap screw. Chucks can be interchanged in the field, but it is recommended to keep chucks attached to the lead screw. We can manufacture special chucks to meet customer specifications, please contact the factory for additional information.

To determine which size chuck you need, use the diameter of the tap to choose the tap bushing needed. Use the size of the chuck that matches the bushing.

*The actual shank diameter of the tap should be used. The tap size is only a reference. Different tap manufacturers may use a different shank diameter.

The #3 chuck is an 1-1/16” adjustable spindle adaptor designed to use adjustable tooling manufactured by several readily available “off the shelf” vendors.

There are several benefits of using adjustable adaptors. One benefit is the additional fine adjustment of tap depths between tap changes. Another advantage is the ability to install quick change adaptors to facilitate rapid changing of taps. Another benefit to adjustable adaptors, is that your shop can use standardized tooling for all your tapping operations and be able to swap taps from operation to operation.

Benefits of #4 Chuck - Quick Change Bearing

The Jiffy quick change chuck and tap bushing system are better:
  • To change a tap bushing you don’t need any type of wrenches or keys. Just push back on the knurled section of the chuck and the tap bushing pops out.
  • To install a new bushing, align the square driver in the back of the bushing flange with the cut out in the top of the chuck and push. The knurled part of the chuck will pop forward and lock the bushing in place.
  • To change a tap in a bushing, you don’t have to remove the bushing from the chuck. Just push back the small bushing flange and the tap will come out. Insert a new sharp tap and push tap in. The bushing flange will pop back in place, securing the new sharp tap.
  • All tap changes can be accomplished in under a minute.
  • Can utilize existing quick change bushing manufactured by, Bilz, T.M. Smith, etc.
Order number for chuck as a separate line item and a bushing for each size tap.
Note: Change lead screws when changing tap pitches.


*The actual shank diameter of the tap should be used. The tap size is only a reference. Different tap manufacturers may use a different shank diameter.
