A magnet member cutting apparatus comprises a temperature controller for temperature control of a coolant. The coolant at a temperature controlled by the temperature controller is supplied to a cutting region from a coolant discharging device via a coolant supplying path. While the coolant is supplied to the cutting region, a magnet member which is a sintered rare-earth magnet member is cut by a cutting blade having a cutting edge including a mixture of abrasive grain made of a super hard abrasive grain and heat resistant resin made of a phenol resin. Preferably, the coolant is used in circulation, the coolant temperature is maintained at 20° C.˜35° C., the cutting blade rotating speed is 1000 m/min˜3000 m/min, a volume rate of the abrasive grain to the cutting edge is 10%˜50%, and the cutting edge further includes metal powder.
