Walter 15/16 X 1 Sst Core Cut Weldon Shank tr_100 Accepts bits with 7/16-14 TPIDimensions Diameter 15 16" Length 1" Description 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
