Even without water as a lubricant, they can still withstand the huge heat generated by the hole saw when it rotates at high speed. For optimized performance and extended lifespan, you can also use water as an additional coolant to keep the saws cool and sharpened.

A hard storage bag to keep your tools organized and easily accessible. It is applicable for most brittle and hard material such as tiles, ceramic, marble, glass (except tempered glass), granite and terrazzo.
  • Precise Positioner Ceramic tile drill guide jig is made of high-density vinyl acetate copolymer which has the effect of forming beads when meeting water. It can effectively fix the drill position of the hole saw, The precise positioning system firmly clamps the hole saw to prevent sliding or improper operation damage.
