The MILWAUKEE® HOLE DOZER™ 11/16 Hole Saw Bi-Metal Cups are made in the USA and feature RIP GUARD™ for the strongest tooth in the industry backed by a limited lifetime tooth break warranty. Each tooth is built with more steel behind the cutting edge for added strength. The HOLE DOZER™ hole saw blade includes a PLUG JACK™ , an all access slot for plug removal. The Milwaukee PLUG JACK™ gives access lower into the cup for thick material and higher towards the teeth for thin material. This versatility increases productivity and eliminates downtime between holes by allowing leverage in multiple positions with consistent hole quality. Combine with Milwaukee’s universal Quick Change Arbor for fast, tool free change outs (49-56-7240, 49-56-7250, and 49-56-9100).
