## Long description

Silver Diamond Hole Saws for Porcelain/Gres Silver set M14, 11 pieces is a kit of diamond-edged core bits designed for cutting precise circular openings in porcelain stoneware (gres) and other hard ceramic and stone tiles. Each crown in the set features a continuous diamond cutting rim and an M14 threaded connection that fits angle grinders or drill adapters with M14 mount. The set covers a range of hole sizes commonly required for tile installation, plumbing, electrical boxes and HVAC penetrations, delivering accurate, clean holes with reduced chipping when used with appropriate technique and cooling.
Advantages
The diamond cutting edge provides accelerated material removal on hard glazed and unglazed tiles while maintaining edge durability. Continuous rims produce smooth hole walls and minimize tile breakage when compared to non-diamond alternatives. The M14 threaded connection ensures secure attachment to angle grinders and compatible adapters for controlled drilling. Supplied as an 11-piece set, the crowns offer versatility across multiple hole diameters needed for fixtures and service penetrations.
Suitable for
 Creating openings for plumbing fixtures through porcelain stoneware and ceramic tiles
 Cutting holes for electrical boxes and conduit penetrations in tiled surfaces
 Installing ventilation or HVAC grilles that require precise circular cutouts
 Tile renovation and replacement tasks where clean drilled holes are required
Key specifications
 Cutting edge: continuous diamond rim for hard tiles and stoneware
 Connection: M14 threaded mount for angle grinders and adapters
 Set composition: 11 hole saw crowns covering a range of diameters (various sizes included)
 Intended materials: porcelain stoneware (gres), ceramic, glazed and unglazed tiles, some natural stone
 Typical use: wet or dry drilling with appropriate cooling and low-speed control
How to use
Mark the center of the desired hole on the tile surface and secure the tile or fixture to prevent movement. Fit the appropriate diamond crown to an M14-compatible angle grinder or adapter and set a low rotational speed where possible. Start drilling at a slight angle to establish a scoring groove, then gradually bring the tool to a perpendicular position while maintaining steady, light pressure. Use frequent pauses and apply water or a coolant stream to reduce heat and prolong the diamond rim life. After the hole is complete, clean the edges and remove any residual slurry.
Usage recommendations
For best results, use controlled, low-speed operation and continuous water cooling when feasible. Avoid excessive force or high speed to minimize chipping and extend tool life. When drilling near edges, support the tile to reduce vibration. Use appropriate personal protective equipment including eye and respiratory protection and follow the angle grinder manufacturer's safety guidelines.
