Product description

  • Upgraded Diamond Drill Bit with Perfect Drilling Performance The upgraded diamond dry drill bit is filled with wax lubricant inside, which melts and cools the cutting surface during dry drilling (water can be used as additional cooling to extend the life of the drill bit). The built-in surface coating can prevent the drill from rusting, with faster cutting speed and longer service life.
  • Precautions for Operation In order to make the work easier, start drilling at a 45-degree angle and gradually raise the drill bit to an upright position. That is so easy to operate.
  • Wide Range of Uses The diamond drill bit set is suitable for drilling stone, granite, marble, porcelain, ceramics, tiles and hard tiles (not suitable for wood). Our diamond dry drill bits are suitable for both industrial and household use under hard working conditions.
  • Compatible with Most Machines The diamond drill bit is designed with a strong 1 4" hex shank, which is compatible with most drills and machines, such as hand drills, angle grinders and bench drills. It can also be matched with side grooves to help remove debris and drill smoothly and quickly. It is also very useful for accurate projects.
