BIHUI Quick Change Diamond Drill Bits — Swap Sizes Instantly, Drill Clean Holes

Stopping to chuck and re-chuck bits between hole sizes wastes time on a job full of penetrations. BIHUI quick-change diamond drill bits use a universal shank that swaps bit sizes instantly — no tools, no adapters — so you move from a small anchor hole to a large fixture without breaking stride. An aggressive diamond matrix drills clean holes with smoother edges in porcelain, glass, marble, ceramic, and stone.

They're built for the real work: shower walls, backsplashes, countertops, and dense floor tile. Pair them with cooling wax to keep the bits cool and extend their life on dry holes.

Why Tile Pros Choose It

Pro tip: Start at an angle to break the glaze, then bring the bit vertical, and keep it cool with water or cooling wax — heat is the enemy of any diamond bit. Ease off as you break through to avoid blowing out the back of the tile.
