CRL EDD Series Standard Plated Diamond Drills were designed for a cost-effective method of drilling, and are our most popular and economically priced drill. The sturdy solid steel construction allows quick hole drilling with clean break-outs. The generous 3/8" (9 mm) diameter shank allows for a sure fit into any drill machine. Although diamond plated, this drill may be sharpened one time after it is worn out with a CRL Sharpening Stone to expose some of the remaining diamonds to extend its work life.
