FOCSTOL Diamond Drill Bits Set — 10-Piece Kit for Precision Tile and Stone Drilling

Elevate your drilling projects with the FOCSTOL Diamond Drill Bits Set, a 10-piece kit crafted for accuracy across porcelain, ceramic tile, glass, marble, granite, quartz, and similar hard materials. The package includes eight diamond-tipped drill bits in four common sizes, plus two PH2 driver bits and a 1/4 inch quick-change hex shank for fast, secure bit swaps during work.

Whether you’re installing a new backsplash, drilling clean holes in glass panels, or routing through natural stone, this kit is designed to deliver controlled cuts, smoother finishes, and reduced chatter. The bits are designed with cooling wax inside to dissipate heat and carry away chips, while premium diamond particles bonded with vacuum brazing promote sharper cuts and longer service life.
