The new hole saws feature a segmented edge for faster cutting, and wide, offset slots for easier plug removal. They are available in sizes from in ¾ in to 2 1/2 in.

"Drilling abrasive materials can be difficult and often causes increased wear on the hole saw," says Todd Taylor, senior product manager at Milwaukee. "By utilizing tungsten carbide grit, the new models can cut abrasive materials with less wear and the grit edge still leaves a clean finish cut."
Milwaukee Electric Tool has also improved its line of recessed light hole saws, which feature a continual carbide grit edge.
