Festa Deimantinis karūnos vakarėlis, O 6 mm

Professional diamond core bit with shank for precise and fast drilling into stone, paving stones, tiles, granite, marble, and other extremely hard materials—not only in the construction industry. Diamond layer thickness: 10 mm, long service life; the core bit can be used without any additional tools; for smooth surfaces, we recommend using the 20379 drill and core bit guide; recommended procedure - Clamp the core bit into a drill or cordless drill. Recommendation: The drill should have sufficient power and high RPM. Begin drilling the desired hole at a 45° angle; the core bit and the drill’s rotational speed will immediately secure it in the desired location; slowly and with even pressure, straighten the drilling direction to a vertical position. We recommend cooling the core bits while drilling, especially when working with hard tiles.
