【Upgrade Process】FixltFast 4 1 2 Cut-off Wheel adopts Reinforced high-manganese steel core with diamond-fused edge technology，1.2mm ultra-thin profile reduces friction by 40%，24 precision laser-cut vents prevent overheating，which improves the cutting efficiency by 30% 【Avoid Injury】FIXLTFAST 4 1 2 diamond cutting discs employ advanced electroplating techniques and a 24-hole design technology. The ensures safer operation, Delivering enhanced control, Reduced sparks and minimal dust 【Compatibility】1 equals 100, the diamond cutting wheel can perform 6,000 cuts on metal. Lt operates at a maximum speed of 13,200 RPM and 80 meters per second, Allowing multiple cuts on metal. Lt is especially suitable for dry cutting of metal, Iron, Alloy steel, Aluminum, And various pipes, And comes with a sturdy polypropylene storage case 【Product Size】Diameter 4.5 inches (115 mm), arbor hole 7/8 inch (22.23 mm), thickness 0.047 inches (1.2 mm). Each boxed product comes standard with 4/5 inch (20 mm) and 5/8 inch (16 mm) arbor assemblies, Suitable for angle grinders and bench grinders 【Enhanced Safety】Each cutting disc comes with an individual packaging bag to prevent abrasion and damage during transportation. Lt must be securely installed; Gloves, Safety goggles, Masks, And face shields must be worn during operation FixltFast diamond metal cutting wheel is designed specifically for cutting low-carbon steel. FixltFast grinding blades have undergone multiple rounds of research and testing, and 2.0 has solved this problem. Add a thinning process on the edge of the original high manganese steel body, and permanently solder diamond particles to the edge of the steel core to make the diamond completely flat at the edge. High manganese steel substrate has porosity, which can better dissipate heat during cutting process. The overall design of this product makes dry cutting sharper, faster, more environmentally friendly, and reduces burrs.
