Steel Arbor Spacer, 1-1/4″ Bore, 5/16″ Wide

Description

The 5/16″ wide arbor spacer closes the gap between the 1/4″ and 3/8″ positions in the Pro-Line spacer range, providing a single-piece solution for stack heights that land at this specific increment on the 1-1/4″ bore spindle. Using one 5/16″ spacer instead of stacking a 1/4″ and a 1/16″ reduces mating surfaces and simplifies assembly of the Pro-Line cutter stack. The machined steel body features precision-ground parallel faces that seat flat against adjacent cutters, collars, and spacers without introducing tilt. Freeborn produces these spacers with consistent bore tolerances across all widths so each size in the Pro-Line set fits the 1-1/4″ spindle with the same reliable, close fit.
