These drill bits are the ideal answer when holes are needed in hard materials, such as porcelain, without the mess of water cooling. They will drill all tiles including hard porcelain, as well as ceramic, granite and marble. They only require a standard power drill with a chuck, (turn off hammer action), and preferably some sort of drill guide.

Specification:

• Premium grade diamond for drilling hard materials such as porcelain.
• Vacuum brazing forms extremely strong diamond bond.
• Hex shank for use in standard drill chucks (turn off hammer action).
• Wax filled. Heat will release wax to lubricate and cool.

Other Sizes: We offer larger sizes up to 65mm dia in premium drills for wet use on drills and up to 117mm on angle grinders.
