CRL PD and PDT Series Metal Bond Diamond Drills — SKU: PDT114

Italian-made metal bond diamond drills engineered for glass cutting performance. The PD/PDT series uses a special diamond-and-bronze bond that cuts faster, runs cooler, and yields the longest life of any diamond drill type—typically 1,000–2,000 holes in 1/4" (6.4 mm) glass with proper maintenance. A full 3/8" (10 mm) deep cutting surface filled with diamonds provides extended life for high-volume glass drilling; these multi-layer drills are optimized for flat, true-running production machines.

Differentiators:

• Metal bond construction for maximum durability in glass drilling
• Extra-long PD shank (1-3/8" x 3/8") for positive grip in holedrives
• PDT Belgian (1/2" gas) thread compatible with U.S. and European drilling machines

Recommended use: production equipment and portable drill machines (e.g., CRL AMZ1) when true running and flat glass support are available. Because of the dense diamond/bronze matrix, these drills are more fragile than resin-bond types—use only on flat glass and in proper drilling fixtures.

NOTE: Always wear appropriate safety gear (gloves, eye protection). Perform work on a flat, horizontal surface. Use a Ground Fault Circuit Interrupter (Cat. No. GF1) when using electric tools with water/coolant. Failure to follow precautions can result in injury.
