Ryobi's masonry bits allows you to drill through brick, block and concrete much faster due to their helix flute design. This larger design of the flutes allows you to make a cleaner cut through the material, and also remove more debris to make a more precise hole. With a variety of individual sized bits from 1/8 in. up to 1 in. in diameter and from 3 in. up to 13 in. in length, 5-pack bit sets and a 12-piece set Ryobi gives you all you need to make your masonry drilling projects fast and easy. Available on homedepot.com and select Florida stores.
