Covington's all new Signature Series blades are here! Our "A" series blade is the top of the line! This model is comparable to or better than MK Diamond's 303. The 6" to 14" models are continuous rim. The 16" and larger feature a segmented rim for better sediment washout on larger cuts. We are so happy with this new line of blades, it's what we feature on our 12" and larger saws now! Sizes from 6" to 24" are in stock and ready to ship!
