Review on 🔪 IVY Classic 26628 Carbide Grit: Unleash the Power of Precision Cutting by Michael Hudson

The included center drill will not drill through porcelain stoneware. Even after drilling an initial hole in the tile with a 5/32" tile bit, after about a minute of drilling, the pilot bit only entered about 1/16" deep. Very noticeable wobbling on this hole saw. This is because the pilot drill has a .225" shank diameter and the pilot hole in the mandrel has a .242" diameter. The pilot drill, which easily drills through the tile, does not fit in the gazebo. See my additional comment below. I will be in touch with Revain to see if I can return this for a refund.
