In an outer blade cutting wheel comprising an annular thin disc base of cemented carbide having an outer diameter of 80-200 mm, an inner diameter of 30-80 mm, and a thickness of 0. 1-1. 0 mm, and a blade section disposed on an outer periphery of the base, the blade section comprises diamond grains and/or CBN grains bound with a metal bond having a Young's modulus of 0.7-4.0x10^11 Pa and has a thickness which is greater than the thickness of the base by at least 0.01mm. The outer blade cutting wheel is capable of cutting a workpiece at a high accuracy and a reduced allowance, improves machining yields, and reduces machining costs. |
