SuperCut Premium Bimetal Bandsaw Blades are a superior blade with high alloy, high speed M2 steel teeth and a spring steel back to provide flexibility and toughness in the blade. Bimetal blades will give lower cost per cut on tough sawing jobs. Bimetal blades are welded by an electron beam under high vacuum to attach the strip of high speed M2 steel to the spring steel back. The teeth are then milled or ground into the M2 steel.
SuperCut Premium Bimetal Blades will cut a variety of materials, including wood, plastics, soft metals, standard steel products, and hard to cut metals such as stainless steel. Bimetal Blades have a higher initial cost than Carbon Tool Steel Blades, but they will generally outlast Carbon Tool Steel Blades by approximately 10 times, so the cost per cut is considerably less. Structural shapes should be cut at a blade speed of 350 fpm (feet per minute) wet, 200-250 fpm dry. When cutting solids, blade speeds should be 300 fpm or less wet, 200 fpm or less dry.
NOTE: all cutting should follow the simple rule of no less than 2 teeth in contact with the cut at all times, while not allowing more than approximately 10 teeth to contact the cut. Any fewer than 2 teeth in contact can allow the material to drop into the gullet of the blade, causing teeth to shear off. Allowing more than approximately 10 teeth to contact the cut can cause the teeth to not remove the waste effectively and can cause binding in the cut and also damage the teeth and set.

I had to clip the protruding "tooth" with my shears and use needle files to clean it up.I've NEVER had this issue with the chinesium iMachinist blades for $14.99 \_(_)_/
Great blade for cutting steel tubing and works on wood.
I teach welding and metal working and these blades are fantastic. We only go through about two of these a year on one bandsaw blade and we cut literally thousands upon thousands of feet of metal for student projects. We have cut items from 8" channel to the smallest square tubing with no problems.
Great blade. Cuts stainless steel and lasts longer than most other blades. Will buy more in time.
Happy with the performance of the blade. Only quirk is the weld is little uneven causing it to click just a tad each rotation of the blade.
