Dry Wet Diamond Core Hole Saw Cutter
Product Show
Diamond hole saw drill bit tools are made of new technology and new materials. The cutting edge is sharp, the opening speed is fast, and the chips are easy to remove. It also contributes to accurate punching, smooth punching, and improved work efficiency. Vacuum brazing technology provides a longer working life, fast and smooth drilling. Laser welding technology can prevent segments from falling off during dry work. Vacuum-brazed side protection provides clean cuts and steel core protection (internal and external). Dry diamond core drills are equipped with angled grooves that extend to the rear end to expel dust. Dry diamond core drills have a unique spiral barrel design that draws dust into the barrel. Heavy-duty core diamond drill bits, laser welded to provide great strength and prevent any bit loss.
Made from top-notch materials and tested for optimal performance, our products are sure to make on-site work easy, smooth and fast. Water lubrication is required when drilling to extend the life of the drill bit set; when cutting hard materials, it is important to ensure that the tool remains cool to avoid damage to the material being drilled and premature wear of the tool. Wet drilling will greatly extend tool bit life.
