BIHUI Diamond Turbo Drill Set (10 pcs) — The Big-Hole Kit for Porcelain and Stone
Plumbing penetrations, drains, and fixture holes in dense porcelain and granite call for more than one bit — and more than one tool. This BIHUI 10-piece set puts the common large-hole sizes, a milling bit, a cutting blade, and cooling wax together so you show up ready for whatever the plumber marked.
The turbo diamond design drills faster with smoother edges and less chipping. Bits run on a 5/8"-11 connection for your angle grinder and can be used wet or dry.
