ABSTRACT:
In a rotary tool adapted for grinding under a flowing liquid film, wherein the particles of abrasive are metal-bonded to a rigid supporting surface, the improvement consists of a network in the supporting surface of grooves having constant depth and constant width and traversing said supporting surface to provide a continuum of centrifugal drainage grooves in the radial direction thereby subdividing said supporting surface into working elements. The ratio of the total area (A.sub.E) of said working elements to the total area (A.sub.G) of said network of grooves: A.sub.E /A.sub.G is at least 1.5. The configuration of the network of grooves is selected such that the angle of intersection of any side of any channel with the radius at any point is an acute angle between 0.degree. and 75.degree..
