Review on IRWIN 326023 Straight Shank Masonry by Jake Meyer

I've used this bit for drilling 4" brick facings and for drilling anchors in 6-bag concrete. Works perfectly, the grooves are wide enough for the holes to clean themselves. I work as a contractor and use these tools every day. I prefer this Irwin bit to the cheaper Vermont American or often more expensive DeWalt bit because of the wider flutes. This drill bit cuts through masonry like oil.
