M.k. Morse 001977 bi-metal portable band saw blade 44-7/8″l x 1/2″w , 0.025″ thick, 14 tpi, 25pk use on machinable metals, including stainless steel, pipe, tubing and solids. Bi-metal blades offer high heat, wear and shock resistance. Variable pitch allows a broader range of applications and reduced vibration when cutting. This combination results in the longest blade life among competitive blades. These rugged, heat treated blades are welded-to-length in our manufacturing plant. They install easily, last a long time, and smoothly cut a wide variety of materials. features: shock resistant teeth great for cutting machinable metals variable pitch allows a broader range of applications and reduced vibration straight pitch teeth for better chip clearance and fast cutting
