Dry drill bits with specifications above 8MM (dry drills with a diameter of 6MM do not require cores). During use, coring is required for every 1 - 3 holes drilled. When the drill has residual heat to cool down, and the wax is not solidified, put the drill head down, hit the body, and the ceramic core will be shaken out.2. Do not use an electric drill with a speed lower than 2000 rpm, otherwise it will affect the service life of the drill bit.3. When using a dry drill, all the porcelain does not need to add water. During use, the drill body heats up to form steam to cool the drill bit. Therefore, cooling water should not be used, otherwise it may cause wax vapors not to appear, which is contrary to performance. 1) we accept Alipay, West Union, TT.
