glass core drill bits (1 Viewer)

[rhane71]

Does anyone here have a glass drill bit I can use? I need to drill (1) 1-1/2" and (2) 1-3/4" holes in a sump. These sizes are for (1) 3/4" bulkhead and (2) 1" bulkheads. If anyone can help me with any of these please let me know. If not I will take the tank in and have someone else drill them. I only wanted to practice on drilling them myself. Thanks...

I have a 1 3/4" bit. You can get 1" and 3/4" bulkheads that fit the 1 3/4" holes so you only need one size bit. I may have a 3/4" bulkhead I know I have the 1".
