## Summary description

Diamond drill bit for porcelain Smart SM-25-350 with a 35 mm cutting diameter. Designed for drilling porcelain and similar hard glazed ceramics, it provides precise circular holes for sinks, tiles and sanitary fixtures. Used with water cooling and low speed to reduce heat and prolong tool life, suitable for professional and DIY tile installation and repair tasks.

## Long description

Diamond drill bit for porcelain Smart 35 mm, model SM-25-350 is a specialized core bit designed to produce clean, precise 35 mm circular holes in porcelain and similarly hard glazed ceramics. The cutting edge is diamond-segmented to ensure efficient material removal while maintaining hole geometry. Intended for use with low drilling speeds and continuous water cooling, this drill bit minimises thermal stress and extends service life. It is compatible with standard drill chucks and core bit holders used in tile and sanitary installation.
Advantages
The diamond-segmented rim provides accurate cutting performance and long-lasting wear resistance when used with appropriate cooling. Its 35 mm diameter delivers consistent hole size for fitting sinks, taps, drains and other sanitary fixtures. The bit’s construction reduces chipping on glazed surfaces and preserves edge quality, which is important for visible installations. Use at low speeds and with water cooling improves cutting efficiency and lowers the risk of cracking delicate ceramic pieces.
Suitable for
 Drilling precise 35 mm holes in porcelain tiles and glazed ceramic
 Creating openings for sink and tap fittings in countertops and tiles
 Tile repair and retrofit work where clean circular holes are required
 Professional tiling and DIY bathroom or kitchen installation projects
Key specifications
 Cutting diameter: 35 mm
 Tip type: diamond-segmented rim for hard glazed surfaces
 Intended materials: porcelain and hard glazed ceramics
 Recommended cooling: continuous water cooling during use
 Recommended speed: low RPM suitable for core drilling in ceramics
 Shank compatibility: standard drill chuck/core bit holder compatible
How to use
Secure the porcelain tile or fixture to prevent movement and mark the center of the hole. Fit the diamond drill bit into a compatible drill or core holder, set the drill to a low speed, and start drilling with light pressure. Keep the cutting area flooded with water or use a continuous water feed to cool the bit and remove debris. Withdraw the bit periodically to clear slurry and inspect progress. Maintain steady, controlled pressure and avoid forcing the bit to prevent overheating or cracking the ceramic.
Usage recommendations
For optimal results, use steady low RPM drilling with continuous water cooling and firm workpiece stabilization. When drilling delicate or large-format tiles, practice on a scrap piece first and support the tile from the rear to reduce vibration and chipping. Replace the bit if cutting performance significantly degrades to avoid damage to finished surfaces.
