Abstract
A circular cutting wheel having a plurality of radial slots evenly spaced about the periphery thereof and a diamond-bearing arcutely shaped cutting member bonded to the periphery thereof between each of the radial slots, the core further including a plurality of coolant pumping vane members formed as arcuate grooves on each side of the core extending radially outwardly from the core in the intended direction of rotation of the blade and terminating at the core periphery, thereby providing the means with which to distribute and maintain a fluid coolant on the sides of the core and to pump such fluid coolant to each of the cutting members. A method of cutting natural and artificial rock materials utilizing such a blade which includes providing a pumping action to a fluid coolant in the area of cut at the blades' cutting edge.
