Product description

  • Premium Quality These diamond bits are made of industrial grade carbon steel and have a nickel coating to prevent corrosion. The drill bit is made of diamond coating, which is very suitable for machining accurate and smooth holes in glass or other brittle hard materials.
  • Powerful Suction Cup & Stability Upgrade double suction cup design, provide more powerful suction than the single suction cup. It can firmly absorb the smooth surface and effectively fix the drilling position of the hole saw. The precise positioning system firmly clamps the hole saw to prevent slipping and damage to objects caused by improper operation.
  • Easy to Use The natural rubber suction cup has good resistance and is very strong, which can keep the drill locator on a smooth surface. Adjustable positioner, strong clamping force, the guide drill will not move, and the operation is smooth.
