Steel Arbor Spacer, 3/4″ Bore, 5/16″ Wide

Description

The 5/16″ wide arbor spacer occupies the intermediate position between the 1/4″ and 3/8″ standard sizes, covering profile stack heights that don’t fall at a quarter-inch increment. In a comprehensive Freeborn Mini-Pro spacer set, this piece eliminates the need to stack a 1/4″ and a 1/16″ spacer to reach the 5/16″ position — one piece, one fewer mating surface. Bored for the 3/4″ Mini-Pro spindle, the precision-machined steel body seats flat with parallel faces that keep the cutter stack aligned. Freeborn produces these spacers with consistent bore tolerances across the full width range so each size fits the spindle with the same close, repeatable fit.
