## Long description

Diamond Hole Saw Expert+ 55 mm with an M14 shank is a diamond-segment cutting tool designed for drilling precise round openings in hard surfaces. Intended for use with angle grinders or compatible rotary tools that accept an M14 arbor, this hole saw is specified for a maximum rotational speed of 12,000 RPM. It is suitable for creating clean holes in tile, ceramic, porcelain and thin stone where a durable diamond cutting edge is required.
Advantages
The diamond segments provide consistent cutting performance and a longer service life compared with conventional abrasive cups. The 55 mm cutting diameter produces accurately sized openings for fixtures, pipes and conduits. The M14 shank offers quick mounting on most angle grinders and many rotary tools, while the 12,000 RPM rating ensures effective cutting when used within the recommended speed range. The tool’s construction minimises chipping on brittle surfaces when operated with appropriate technique.
Suitable for
 Drilling holes in wall and floor tiles for plumbing and sanitary fixtures
 Creating openings in ceramic and porcelain panels for electrical conduits
 Cutting precise round holes in thin natural and engineered stone
 Site work by installers and tradespeople requiring repeatable hole sizes
Key specifications
 Cutting diameter: 55 mm
 Shank type: M14
 Maximum rotational speed: 12,000 RPM
 Cutting material: diamond segments bonded to metal matrix
 Intended materials: tile, ceramic, porcelain, thin stone
How to use
Fit the diamond hole saw onto an angle grinder or rotary tool with an M14 arbor and secure it according to the tool manufacturer’s instructions. Mark the centre of the desired hole and, if possible, use a guide or starter bit to prevent wandering. Begin drilling at low speed to establish a groove, then progress with steady pressure and moderate feed to avoid overheating and chipping. Use coolant or intermittent water application on suitable tools to reduce dust and extend blade life. Keep the tool perpendicular to the work surface and allow the diamond segments to cut without excessive force.
Usage recommendations
Use appropriate personal protective equipment, including eye protection, a dust mask and gloves. Select an angle grinder or rotary tool rated for the M14 shank and capable of safe operation up to the tool’s maximum RPM. For brittle tiles, support the workpiece and consider wet cutting or intermittent cooling to minimise chipping. Replace the hole saw when cutting performance visibly declines.
