The metal bond grindstone includes: a metal bond; abrasive grains bound by the metal bond; and pores having a pore size of 50-200 μm, such that a porosity in an entirety of the metal bond grindstone is 50-65 vol %. A number of the abrasive grains on a grinding surface excluding the pores may be 700-6500 grains/cm2. The abrasive grains may be diamond abrasive grains, and a grain size of the abrasive grains may be 4-20 μm in median size. The metal bond grindstone may have a grindstone strength of 40-95 MPa.
