CRL PD Series 1/4" Metal-Bond Diamond Drill Bit for Glass/Tile

• Designed for high-volume glass fabrication
• 3/8" diamond matrix depth for extended cutting life
• Two mounting styles: straight shank or Belgian (1/2" gas) thread
• 3/8" x 1-3/8" (10 x 35 mm) shaft for a positive grip

CRL PD and PDT Series Metal Bond Diamond Drills (SKU: PD14) use a specially formulated diamond-and-bronze bond for maximum performance when drilling glass. These Italian-made, multi-layer metal bond diamond drills cut faster, run cooler, and deliver the longest life of any diamond drill type—typically 1,000–2,000 holes in 1/4" (6.4 mm) glass with proper wet sharpening and maintenance. The full 3/8" (10 mm) deep diamond cutting surface extends tool life while improving throughput for production glass drilling machines and portable drill units alike.

The CRL PD Series features an extra-long 1-3/8" x 3/8" (35 x 10 mm) shank for secure holding in chucks. The CRL PDT Series uses Belgian-style mounting threads (1/2" gas), a common choice for U.S. and European glass drilling machines seeking reliable, repeatable performance.

Safety & Usage Notes: Always wear gloves and eye protection, and drill on a flat horizontal surface. Use a Ground Fault Circuit Interrupter (Cat. No. GF1) when operating electric tools with water or coolant. Metal bond drills are more fragile than matrix styles and should be used in true-running machines for best results.
