Freshening up a saw is as easy as swapping out the old blade for this sharp cutting tool. The blade that comes with the Evolution EVOSAW230 is one of the best metal-cutting saw blades around — but it does still have limits. The 230BLADEST is exactly the same as the blade that comes with this saw. It’s also a direct replacement metal cutting blade for other circular saw models, including the MK Morse CSM9MB, Jancy MCSL09 and Steelmax S9.Evolution 9-inch circular saw blades are designed to be superior to standard saw blades and abrasive discs in every way. This 48-tooth blade is made of tungsten-tipped steel that spins at up to 3,000 RPM. It produces no heat, no burrs and practically no sparks. You’ll have a work-ready finish and much safer operation while working on everything from steel plating to roofing. A 1-inch arbor safely rotates the blade while allowing for bevel adjustments.
