Design change has reduced the number of parts and allows easy takedown for cleaning and maintenance. Positive locking in increments of .001 by hand adjustment plus a locking ring eliminates any possibility of an adjustment change when in use. Unit takes 1/4"-28 threaded shank cutters up to and including 5/8" diameter. 1 lbs (0.5Kg) shipping weight.
