Review on 12-Piece M054 Masonry Ceramic Concrete Mgtgbao Set by Shawn Reiter

Cuts through concrete like butter. The ends are well sharpened. I haven't had a chance to try them on a large project (like installing fiber cement siding) but on the smaller projects I've used they've held up well and cut holes with ease. I took photos of all the pieces to show the style of the lace, not sure how well it came out but it shows the shapes. One of the small pieces cut a hole in the rock in about 15 seconds. Its depth is about half an inch. This is a type of drill whose tips must be kept cool, otherwise they will quickly overheat and become blunt.
