Our new Husky Blade is extremely versitile, and can be used on any power saw - gas, electric, battery operated, and will cut virtually anything on site! This exceptional diamond blade has been specially designed for Urban Search & Rescye teams because it will cut any material. It has been specifically crafted to reduce heat during the cutting process. Some features of this blade: (1) Blade for Blade, the ratio is 100:1 of a normal steel (aluminum oxide) or concrete (silicon carbide) blade. (2) Cuts any material in the fire service. Especially works well in cutting metal locks, bars, concrete, steel, roll-ups, car posts and any material found in a forcible entry situation. (3) The 4.5" blade can be used with a battery operated grinder to cut hurricane glass found on coastal buildings or items found in limited spaces and (4) The cutting surface of this blade is made with diamonds, carbide and tungsten (a heat and corrosive resistant material). It makes the blade almost indestructable when cutting any material. This blade is a forcible entry MUST, along with a light weight saw such as the Partner K-750, 12-inch model. Can be used on any power saw and has a double arbor size 20mm with a knockout to 1 inch. Available in 4.5-inch, 12-inch and 14-inch. --- The new and improved Husky Fang has all of the same features as our huskey blade, but features a cutting surface made with more diamonds, carbide, and tungsten (a heat and corrosive resistant material).
