5/8 inch masonry bit
This masonry bit just eased through the concrete like I was cutting wood. I pre drilled the holes with a 3/32 masonry bit then used the 5/8. I usually have to put a lot of pressure on masonry bits but this one went right in. Best bit I have

Great drill bit
Would RecommendBought this drill bit to drill 14 anchor holes in a concrete pad. This was by far the best concrete bit I have ever used. Each hole was 8” deep and the average time to drill each hole was less than 1 minute.
