Tungsten carbide saw blades are designed for cutting wood. However, the cutting effectiveness of a tungsten carbide saw is mostly determined by the geometry of the blade, the sharpness of the teeth, and the chip load per tooth. The process for manufacturing, maintaining the saw’s optimum geometry, sharpness and load is referred to as the elements of circular carbide saw blades grinding.
How to choose the grit size of Diamond grinding wheels for sharpening carbide saw blades:
240# and 400# grit size are usually used for tungsten carbide saw blades. Generally speaking, 240# diamond grinding wheels are mainly used for coarse grinding tungsten carbide saws, while 400# diamond grinding wheels are for fine grinding tungsten carbide saw blades.
The comparison between these two types shows that 240# diamond grinding wheel is more durable than 400# diamond grinding wheel, while 400# diamond grinding wheel has better grinding effect than 200# wheel does.
