Grizzly T10808 specifications Step Jaws, Flat Jaws or Cole Jaws

Step Jaws

The step jaws have two outside profiles of differ- ent circumferences designed to expand into the recess cut into the workpiece. The surfaces of the jaws have ridges that push into the wood which increases the gripping power.

The center surfaces of the step jaws are ridged and can grip a dowel-type workpiece from the outside that is fed through the chuck and spindle bore.

Basically, step jaws combine the capabilities of the round jaws and the pin jaws, but are much more versatile than either of those jaws alone.

Flat Jaws (or Cole Jaws)

Used with included grip studs, flat jaws are pri- marily used to finish the bottom of a bowl-type workpiece (see examples below). The included studs are 13 and 18mm in height and are rubber coated to prevent marring. Use the stud set and configuration that has the most surface contact with the workpiece.
