35mm Diamond Holesaw Bit

The 35mm Diamond Drill Bit is used to drill the correct size hole for installing a standard 3/4" bulkhead in a glass aquarium, sump, or reservoir.

This diamond-coated drill bit creates a clean, accurate opening for the bulkhead fitting and is intended for use on non-tempered glass only. Use with water cooling while drilling to help protect the bit and glass during installation.

Features:

• 35mm diamond-coated drill bit
• Correct hole size for most standard 3/4" bulkhead installations for return lines.
• Designed for drilling glass aquariums and compatible glass vessels
• Creates a clean opening for bulkhead plumbing
• Ideal for aquarium plumbing, ATO containers, sumps, and other water-holding applications
• Use with water cooling during drilling
• For non-tempered glass only

Important: Always confirm the required hole size for your specific 3/4" bulkhead before drilling. Do not drill tempered glass. Use steady pressure, keep the bit cool with water, and follow proper glass-drilling safety practices.
