Šakotuvas Festa Deimantinis karūnos vakarėlis, O 12 mm

Professional diamond core bit with shank for precise and fast drilling into stone, paving, 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.
