These Standard Plated Diamond Drills (SKU: DDK5) are optimized for glass drilling — a cost-effective, general-purpose diamond drill bit for clean, quick holes in glass and ceramic. Sturdy solid-steel construction and a smooth continuous rim produce clean break-outs. All sizes feature a 3/8" (10 mm) diameter shank for use in common tripod and cup‑style drilling machines. Although plated, each drill can be sharpened one time with a CRL Sharpening Stone to expose remaining diamonds and extend service life, lowering your cost per hole.

Order one of the sets below to cut cost per drill; a Drill Starter Kit is also available and includes the CRL2 Drilling Machine, coolant, drilling ring, and five EDD glass drills. NOTE: Always wear proper safety gear, including eye protection, and work on a flat, horizontal surface. Use a Cat. No. GF1 Ground Fault Circuit Interrupter when operating electric tools with water or coolant to reduce risk of injury.
