Drilling holes in concrete! Fun! Not being sarcastic. What guy does not like drilling holes in concrete.
I bought a brand new Milwaukee 7/8" concrete coring bit so that I would know that the holes were as close to 7/8" as I could get, but the bit was 0.923" in diameter. How bizarre. I can't imagine that Milwaukee's quality standards are that low. Must have been some type of mistake on the labeling or something.
So, I already had a 7/8" masonry bit and am using that. So far, so good, at least the drilling part. I don't want to take off my template and see if the anchor slides in correctly, because I am very unsure of how close I can get the template to where it is now when replacing it.
