The stone comprises a body of readily machinable metal with a cutting face in the form of an abrasive liner adhesively bonded to a contour face complementary to the contour of the workpiece. Coolant passages within the body of the stone extend through the abrasive liner and adhesive substrate and flush coolant directly between the cutting face and the workpiece. |
