## Summary description

Diamond hole saw by Expert+ with a 25 mm cutting diameter, M14 threaded arbor and maximum rotational speed of 12,000 rpm.

## Long description

Diamond Hole Saw Expert+ 25 mm is a diamond-segmented cutting tool with a 25 mm bore diameter and M14-compatible arbor interface, intended for creating precise circular openings in hard surfaces. The tool is designed for work on tiles, ceramics, porcelain and thin natural or engineered stone where clean, accurate holes are required. It is compatible with angle grinders and drilling tools that accept M14-threaded arbors and is rated for a maximum rotational speed of 12,000 rpm to match common handheld power tools used in renovation, plumbing and tiling tasks.
Advantages
The diamond cutting edge provides durable abrasion resistance and maintains cutting performance over repeated uses, delivering accurate circular holes with reduced chipping on brittle surfaces. The M14 arbor connection ensures straightforward mounting to a wide range of angle grinders and compatible drill adapters, while the compact 25 mm diameter is suitable for typical fixture and pipe penetrations. A maximum speed rating of 12,000 rpm helps ensure stable cutting when used within tool limits.
Suitable for
 Cutting holes for plumbing pipes and fittings in tiled walls and floors
 Drilling openings for electrical boxes and conduit in ceramic or porcelain surfaces
 Creating precise holes for fixtures during bathroom and kitchen renovations
 Making sample or access holes in thin stone and engineered stone panels
Key specifications
 Cutting diameter: 25 mm
 Arbor connection: M14-thread compatible
 Maximum rotational speed: 12,000 rpm
 Cutting material: diamond-segment edge for hard brittle surfaces
 Typical applications: tile, ceramic, porcelain, thin stone
How to use
Secure the diamond hole saw onto an M14-compatible arbor, then mount the arbor in the tool appropriate for the job, such as an angle grinder or drill with M14 adapter. Mark the center point of the hole on the workpiece and start cutting at low speed to establish the groove, then increase speed carefully up to the tool and cutter limits while maintaining steady pressure. Use consistent, moderate feed without forcing the cutter to avoid overheating or excessive wear. For tile, porcelain and ceramic, intermittent cutting and cooling pauses can reduce chipping.
Usage recommendations
Use appropriate personal protective equipment including eye protection, dust mask and hearing protection. For best results on glazed tiles and porcelain, use water cooling or periodic wetting to extend tool life and reduce dust. Ensure the tool’s maximum speed is not exceeded and follow the power tool manufacturer’s safety instructions.
