My invention related to improvements in tools for turning and dressing grindstones and emery-wheels, and to that class of tools in which the cutting action of the tool upon the grindstone or emery-wheel is caused by wheels or cutters revolving by contact with the revolving grindstone or emery-wheel to be dressed or turned. The objects of my improvements are, first, to produce a wheel or cutter which is strong and durable, and which does not become dull by use, but retains its cutting properties substantially unimpaired until it is worn out; second, to mount such wheel or cutter in its holder in such a manner that the parts of the tool upon which the wear principally comes may be easily and cheaply replaced.
