Switching bits mid-project because one won't bite into concrete, then again for tile, wastes time you don't have. This eccentric drill bit set uses a curved-tip design to drill precisely across concrete, masonry, metal, glass and ceramic tile, so the same set follows you from one surface to the next without a swap. It attaches to the electric drill you already own, so there's no separate tool to buy or learn.

As a power tool accessory, this masonry bit fits directly onto your existing electric drill, giving professionals and do-it-yourselfers the same simplicity either way. Whether you reach for it as a drill bit for tile or turn to it as one of the glass drill bits in your kit, the curved tip and high-hardness build are made for accurate, efficient drilling on demanding surfaces.
