WebThe diagram below illustrates this principle; while a zero rake tool can be sharpened down to a stub, ... This sharpening necessitates removing the top half of the rod, followed by further metal removal for the clearance and rake angles. The result is a fragile cutting tool that is essentially unsharpenable. WebMay 29, 2024 · However, if it is clamped both sides of the cut, the positive rake blade will give you a clean and fast cut. To prevent self-feeding, sliding miter saws and radial-arm saws require a blade with a negative tooth angle. In general, a blade with a positive hook angle is a faster-feeding blade and one with a negative hook is less aggressive.
