Bison Chuck |
Bison Chucks are high precision scroll chucks which are well suited to work which requires close tolerances. The Bison Chucks come with two sets of jaws, inside and outside. The inside jaws are installed when the chuck is shipped. With the use of spindle nose adaptors, some Bison Chucks can be used with more lathes than are listed below. An adjustment wrench and a mounting wrench are supplied with each Bison Chuck. |
