Walter 9/16 X 1 Sst Core Cut Weldon Shank belt-length-72 withstands 500 hours of salt-sprayDimensions Diameter 9 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
