BIHUI Cooling Wax for Diamond Drill Bits — Cooler Bits, Cleaner Holes, Longer Life Heat is what kills a diamond drill bit — it burns out the segments and glazes the bit so it stops cutting. BIHUI cooling wax is the cheap insurance against that. Dip a warm bit to form a coating, then drill: the wax absorbs heat and lubricates the cut, preventing segment burnout and glazing while giving you cleaner holes with less chipping and blowout. It works with any bit size on porcelain, ceramic, glass, and natural stone, and it's the simplest way to stretch the life of your diamond drill bits on dry holes. A small jar that pays for itself in bits you don't have to replace. Why Tile Pros Choose It Protects your bits: Absorbs heat to prevent burnout and glazing Cleaner holes: Lubricated cutting means less chipping and blowout Longer bit life: Stretches the life of every diamond bit Any bit size: Dip-on coating works universally For dry drilling: Cooling where you don't have water Cheap insurance: Saves far more in bits than it costs Pro tip: Re-dip the bit every few holes — one coating doesn't last all day. Let the bit warm slightly first so the wax sticks, and you'll get a coating that actually carries heat away from the cut.
