CRL 2-1/4" Belgian Metal-Bond Diamond Core Bit for Glass & Tile

• Straight shank and Belgian thread type (Belgian mount: 1/2" gas thread)
• 3/8" diamond matrix depth (10 mm deep cutting surface)
• Two mounting styles: Straight shank or Belgian thread
• SKU: PDT214 (CRL PDT Series metal bond diamond drill)

CRL PD and PDT Series Metal Bond Diamond Drills use a multi-layer Italian-made diamond and bronze bond engineered for glass drilling. These metal bond diamond drills deliver extended life and consistent cutting in glass—typically 1,000–2,000 holes in 1/4" (6 mm) glass with proper wet sharpening and maintenance. The full 3/8" (10 mm) diamond matrix cuts faster and runs cooler than many alternatives, making these bits ideal for production glass drilling and portable machines like the CRL AMZ1. The PD Series adds an extra-long 1-3/8" x 3/8" (35 x 10 mm) shank for positive grip; the PDT Series features the popular Belgian (1/2" gas) thread preferred by U.S. and European glass drilling machines.

Key differentiators:

• Metal bond diamond matrix for longest life on glass
• 3/8" (10 mm) deep cutting surface for extended use
• Available in straight shank or Belgian (1/2" gas) thread for machine compatibility
• Italian multi-layer construction for cooler, faster cutting

Safety: Always wear gloves and eye protection when drilling glass. Drill only on flat, horizontal surfaces. Use a Ground Fault Circuit Interrupter (Cat. No. GF1) when operating electric tools with water or coolant to avoid injury.
