Spacer rings for saw blades

Spacer rings for saw blades are thin metal rings that reduce the arbor hole of a diamond saw blade so it fits a machine with a smaller spindle. It is a simple and inexpensive accessory that prevents the need to buy a separate blade for every machine with a different arbor size.

From 25.4 mm to 22.23 mm and other sizes

The most common spacer ring reduces the arbor from 25.4 mm to 22.23 mm — the standard size for angle grinders with an M14 mount. Other popular conversions are from 30 mm to 25.4 mm for table saws and from 25.4 mm to 20 mm for certain older machines. Spacer rings come in various thicknesses and are usually supplied as a set containing the most commonly used sizes, so you always have the right ring to hand.

Safe use of spacer rings

Most spacer ring sets contain four to six rings covering the most common arbor conversions, so you always have the right ring regardless of the machine-blade combination.

A spacer ring must fit precisely — both in the blade's arbor hole and on the machine's spindle. A ring that is too loose causes vibration, wear and potentially a dangerous situation. Always check that the ring sits tightly in the arbor and that the blade shows no play after mounting. Replace damaged or worn rings immediately. Never use tape, cardboard or other improvised materials as a substitute — a proper hardened-steel spacer ring is the only safe solution.

Always the right fit

Never use tape, cardboard or other improvised materials as a substitute for a proper spacer ring. Makeshift solutions cause vibration, uneven wear and potentially dangerous situations. A precision-machined steel ring is the only safe option.
