MOUNTING ARBOR FOR SAW CUTTING BLADES

摘要

A mounting for use in mounting rotating cutting blades to the drive shaft of saws is provided. The mounting is an arbor or arbor sleeve having a non-symmetrical outer mounting surface onto which is mounted a cutting blade which contains a similarly configured mounting hole. The arbor or arbor sleeve is designed for use with a cutting blade having a mounting hole which, when viewed from one side of the blade is the same as the outer surface mounting surface, and which viewed from the other side of the blade is not the same. The use of the arbor or arbor sleeve of the present invention with a cutting blade having these characteristics results in the blade being mounted on the saw in only one orientation. The arbor, arbor sleeve, or mounting hole preferably has a generally triangular shape with three sides of unequal length or generally the shape of a trapezium, in order to achieve this blade orientation.
