Featuring high-speed steel cutting edges, these hole saws have shock-resistant teeth that resist stripping. Made of M42 cobalt bi-metal material, they also use a 4/6 positive-tooth configuration for fast, smooth cuts and less vibration. Other features include a 1 7/8" depth of cut and a 3/16"-thick heavy-duty backing plate that eliminates the need for a drive plate. Sold individually (boxed).
