Covington's all new Signature Series blades are top of the line in quality! The "C" series is comparable to or better than MK's 301 blades! We are excited to release these blades and believe them to be of the highest quality. The "C" series blades have a textured rim which allows for better washout of sediment during the cut. Available from 6" to 20" in size, these blades will fit both your trim and slab saw needs!
