Description
Between the 1-5/8″ and 1-3/4″ sizes, the 1-11/16″ collar fills a precise intermediate step in the Mini-Pro depth-control range. On a 3/4″ bore spindle, each sixteenth-inch change in rub-collar OD shifts the effective depth of cut proportionally — a difference that surfaces in the tightness of door-frame joints and panel reveals. This Freeborn ball-bearing collar free-spins against the template or fence face at shaper speed, protecting the guide surface from friction marks. Close bore tolerances from Freeborn ensure the collar seats on the 3/4″ spindle with minimal runout, so the depth you dial in carries through the full run. Use it when the 1-5/8″ collar runs slightly shallow and the 1-3/4″ overshoots — this size gives you the precise intermediate position without touching the fence.
