Forrest saw blades are consistently ranked among the top-performing blades in the industry. Hardened to Rc40-42, the steel plates are laser cut, hand trued and then tensioned to produce a runout accuracy better than 0.001". The long-life C-4 carbide teeth are finely ground and produce clean, finish-quality cuts with little side scoring or tear-out. All blades have a maximum rpm of 7000 (though the maker recommends running the blades at between 3000 and 5000 rpm for best results).
