Achieve precise hole-cutting results with the 8-Piece Diamond Hole Saw Set. Designed for demanding tile installation and stoneworking applications, this kit contains eight diamond core drill bits in different sizes to accommodate a range of hole diameters.
The diamond-coated cutting edges are described as vacuum-brazed, a construction method that securely bonds diamond abrasive particles to the steel cutting edge. This design is intended to support efficient cutting in compatible hard materials.
The set includes 20 mm, 25 mm, 32 mm, 35 mm, 40 mm, 45 mm, 50 mm and 68 mm bits, providing options for different installation and fitting requirements. The bits are supplied in a foam-lined aluminium case that helps keep the set organised and protected during storage and transportation.
Before use, confirm the connection type and whether the bits are suitable for your drill or angle grinder. An appropriate adapter may be required, and wet or dry operation depends on the specific bit design.
