The Bosch PRO Reducing Ring with a 30mm outer diameter and 20mm inner diameter enables circular saw blades with a 30mm arbor hole to be fitted securely onto saws with a 20mm spindle. The 1.5mm thickness provides a flush, stable seating within the blade bore. This combination is commonly required for larger circular saw blades, where a 30mm bore is standard, and makes it straightforward to use such blades on a wide range of saws with 20mm arbors.
