Diamond Coated Glass Drill Bit

This high-quality 60mm (2.34″) Diamond-Coated Glass Drill Bit is designed for clean, precise drilling of glass panels when installing aquarium bulkheads, overflow systems, or custom plumbing. The 60mm cut diameter is perfectly sized for creating holes that fit a standard 1.5″ bulkhead, making it ideal for reef tanks, freshwater aquariums, and DIY sump projects.

Manufactured with a durable diamond coating, this bit provides smooth cutting performance and long-lasting reliability when used with proper lubrication (water recommended during drilling).
