Product description

  • High-quality material The diamond core hole saw drill bits feature a high-quality diamond coating. The housing is made of industrial-grade high-strength carbon steel, and the surface is nickel-plated to ensure high hardness, rust protection, corrosion protection, robustness, and durability.
  • Diamond core hole saw dimensions Cutting diameter 18 mm, cutting depth 40 mm, total length 70 mm, triangular shank diameter 9.5 mm.
  • Efficient Chip Disposal Design The U-shaped chip removal tooth shape and chip removal hole design help dissipate heat and remove dust, while the large through holes on the side can be used for water cooling and easily remove debris. A thick and uniform diamond coating makes the groove edge sharper, and low cutting resistance and stable drilling ensure high-precision and smooth cutting.
  • Easy to use and widely used Use the installed tile hole opener and positioning drill bit to locate the hole. After positioning, remove the positioning drill bit and then use the diamond core hole saw to open the hole directly. Note Remember to add water or coolant during cutting to extend the life of the diamond core hole saw.
