Masonary bits sizing

[yelbike]

Okay so I'm buying a Bosch 1 9/16 rotary hammer 11240.:thumbsup: I need a few bits to go with it but I don't know what size.I need a bit for 1 1/4" PVC and 2" PVC. Does anyone know what that corrolates to. I don't mind a tight fit. I don't like a slopy hole. No pun intended. :licking:

Basically you go a half over so 1 3/4 and 2 1/2.

You will need core bits for holes those sizes. Sit down before you ask the price.

The best prices I found were on Amazon. I needed 2 1/4" and pricey doesn't begin to describe these things.

If the appearance is not critical, I use a 1/4" hammer drill bit. Draw a circle and then start drill holes around the diameter, with a small gap between them. Now take a hammer and bust the core out.
