Bihui 6 Piece Diamond Mill Set

The Bihui diamond mill set gives tile pros and serious DIYers a fast way to enlarge, shape, and clean up holes in porcelain, ceramic, and stone. When a drilled hole needs to grow for a valve, mixer, or bolt, these milling bits grind the edge out to size without cracking the tile.

The set includes six diamond mill bits in a range of sizes, so you can step up a hole or refine an existing cut. Run them wet in a standard drill or angle grinder for cooler cutting and cleaner edges on hard, dense material.

Diamond milling is the trick installers use when a hole saw alone won't finish the job. Tile Outlets stocks this Bihui set for the crew that wants clean openings the first time.
