Mexco 5.5mm, 6mm, 7mm and 8mm Porcelain Drilling Dry Diamond Tile Drill bit set A10VBDPACK

The XCEL Tile drill offers unrivalled performace and cost per cut when drilling the hardest of engineered or natural decorative materials. No water requireddue to a special wax filled core that melts, lubricates and cools when drilling. Diamond tile drill bits mill away at the surface they don't drill like a conventional drill bit. Applying excessive presure will not make the bit drill faster, but will create excessive heat and subsequently reduce the efficiency and life time of the bit. For the bext results use with a high speed drill, recommended minimum 18000rpm. Predominantly this will be with a corded machine not a cordless drill. Drilling fast will make the tile bit last longer.
