These industrial-grade band saw blades are a real game-changer .As my tests SHOWED, they are exceptionally durable and produce smooth, precise cuts every time. They save a lot of time and effort when working with hard and thick materials. The bi-metal construction is of high quality and makes them last longer than other blades I`ve used. The only downside is the price, but I wouldn't hesitate to pay a little more for a superior product in the Cutting Tools category of Industrial and Scientific..
