Diamond Hole Saw 35 mm, Diamond Tile Drill Bit with Pilot Drill, Diamond Coating, Carbon Steel for Tiles, Glass, Ceramic, Porcelain, Marble, DIY and Home Use

Specifications: Diameter: 35 mm. Diamond drill bit is made of high strength carbon steel. The central pilot wick ensures an easy and precise starting point, preventing slipping on smooth surfaces such as glass or tiles. The hexagonal shank (Ø10 mm) ale ensures a firm grip in all standard drills and impact drills, for stable and secure use. Extra thick coarse diamond coating provides unparalleled sharpness, ensuring a fast and smooth cut. The expanded chip evacuation design quickly evacuates debris and accelerates tool cooling, preventing overheating to maintain optimal cutting performance and efficiency. Diamond hole saw is nickel-plated, which strengthens its corrosion resistance and rust resistance, extending its service life. Specially designed for drilling hard and fragile materials such as tiles, glass, ceramics, porcelain, marble, limestone and light granite. It is the ideal choice for DIY enthusiasts and professionals. Unlike standard drill bits, our guide bit has diamond tip and twist design, ensuring effortless initial positioning and accurate cutting, greatly reducing the risk of slipping. Even beginners can make neat and professional holes by following the instructions. Mark the location with a pen. Position the center pilot drill bit on the marked point and drill vertically to create a small starting groove. After the pilot hole is done, remove the pilot bit and continue drilling with the main diamond bit. For optimal results and to extend the life of the tool, we recommend the continuous use of water for cooling during operation. This prevents overheating of the material and diamond crown, as well as premature wear.
