The BMF Silent Continous Rim was originally designed for large format porcelains, but this blade covers a wide variety of hard and precious stone materials. Not only did this blade outperform the number one recommended blade for Dekton in an independent side-by-side performance test, but it also worked exceptionally well on difficult semi-precious stones and other challenging materials. It is a highly versatile all-around blade for lower HP (less than 20hp) saws that might otherwise struggle with hard materials. The ultra-thin rim combined with tightly butted segments renders a remarkably clean finish in both straight and miter cuts, and the reinforced core keeps the blade from deflecting while cutting.
