Durable and Cost Efficient
Smooth Continuous Rim
For Tripod and Cup Type Drilling Machines
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 inch (9 millimeter) 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.
