Milwaukee Tool - 1/4" Diam, 1-1/2" Cutting Depth, Hole Saw - Diamond Grit Saw, Continuous Edge

Diamond grit is one of the hardest cutting materials. It is bonded onto the tip/edge of a steel backing. It is commonly used at high cutting speeds on abrasive materials including plastics, ceramics and stone.

Continuous edge saws have an even strip of abrasive grains bonded to a steel backing. They are used for cutting titanium, graphite and other hard-to-cut materials.
