Abstract
A dicing blade is disclosed which is capable of precisely cutting an object at a high speed without causing significant deposition of swarf upon a cut surface even when the object being cut has a large thickness. The dicing blade includes a ring-shaped cutting blade having a cutting edge formed on the peripheral rim of the ring-shaped cutting blade. At least one slit with a depth greater than the thickness of an object to be cut is formed in the cutting edge.
