1-5/16 X 2 Sst Core Cut Weldon Shank, Walter Surface Technologies, Mfr#: 05A405

Super Speed Tip SST Core Cutters are made with state-of-the-art surface treatment technology that removes porosity during the fabrication process. This creates a perfectly smooth finish which allows for a better evacuation of material while drilling. It also helps to improve product life and reduce drilling time as it decreases friction with the work surface, which in turn reduces the amount of heat generated.
