Olson Cool Blocks - Fits Imports provide superior control and longer blade life when making cuts on your band saw. These slippery cool blocks are crafted from cool-running graphite and resin, allowing them to be snugged tightly against the blade without causing damage to the blade or its teeth. Designed to eliminate flutter and reduce friction, they help extend blade life while guiding a true, accurate cut. Each set includes four blocks, sized 1/2" x 1/2" x 3/4" rectangular, specifically made for 14" import saws. Please note that the size and shape of the blocks may vary from the photo shown.
