Product description

  • WIDE APPLICATION Flintronic diamond drill bit is suitable for cordless drill, lithium drill, bench drill. Widely used for cutting precise holes in glass, ceramic, porcelain, tile, tile, limestone, slate, marble, pumice and fiberglass.
  • PRECISE POSITIONING Compared with traditional glass hole saws, our hole saws have positioning aids. The pilot bit in the center can help you to position accurately, ensure that the drilling will not slip, won't get stuck, and help to cut precise holes.
  • CUTTING EFFECT The diamond surface coating adopts sintering processing method. The cutting edge contains diamond particles from the inside out to ensure that the edge is always sharp. Low cutting resistance and stable drilling create high-precision, smooth cuts with no broken edges for optimal cutting results.
  • CHIP REMOVAL DESIGN The cutter head part of our diamond drill adopts a notch design with clearance holes on the side, which facilitates the entry of cooling water, and ensures that chips and other particles escape from the drill hole during operation, so that the hole can be drilled. The process is more convenient and efficient.
