IN THE KNOW…

What are the arbor adapters and how are they used?

Most all quick-change discs are used with air-driven, pneumatic tools having a 1/4” chuck or collet. By inserting our adapter into the pad in place of a mandrel will allow the holder pad to mount directly on a tool having a male threaded spindle. For example, attaching the 5/8”-11 arbor adapter (Part #385102) will allow a holder pad to mount directly to the threaded spindle of a 4-1/2” right angle grinder. Try it and you’ll be amazed at the grinding ability of a 3” or 4” diameter disc when used on such a powerful tool.
