The Bosch PRO Reducing Ring with a 30mm outer diameter and a 20mm inner bore is designed for use when your blade features a larger 30mm arbor hole but your saw has a 20mm spindle. The 1.2mm thickness provides a precisely seated, stable ring that keeps the blade running true. This larger-format reduction is well suited to heavier-duty circular saw setups where bigger bore blades are commonplace. As always with Bosch PRO accessories, precision manufacturing ensures a reliable, consistent fit every time.
