Abstract
A flat type resinoid grinding wheel, which comprises abrasive grains and phenol resin bond, contains inorganic substance particles in the abrasive grains. The particles are almost the same as the abrasive grains in size but are lower than the abrasive grains in hardness value. Furthermore, the porosity of the grinding wheel is limited to 15% or less.
