## Summary description

Diamond drill bit for porcelain stoneware by GRAPHITE, 53 mm cutting diameter. Designed for drilling hard ceramic and porcelain stoneware with an open-center or continuous rim diamond tip for clean holes. Suitable for use with rotary drills and drill presses at low speed with water cooling; ideal for sanitary fixtures, tile installation and plumbing openings.

## Long description

Diamond drill bit for porcelain stoneware GRAPHITE 53 mm is a purpose-built cutting tool for creating precise, clean holes in hard ceramic and porcelain stoneware. The bit features a diamond-coated rim with an open-center or continuous rim design to ensure efficient material removal and reduced chipping. It is intended for use with rotary drills and drill presses, operating at low speeds with water cooling to maintain cutting performance and extend tool life. Typical applications include sanitary fixture installation, tile work and plumbing openings where a large-diameter, accurate hole is required.
Advantages
The diamond edge provides high abrasion resistance and consistent cutting performance when working with dense porcelain stoneware. The 53 mm cutting diameter allows for large, smooth holes with minimal breakout on the tile surface. Designed for wet drilling, the bit benefits from water cooling to reduce heat buildup and preserve the bond between diamond particles and the matrix. The construction supports stable drilling on both hand-held rotary tools and bench-mounted drill presses when used at recommended low speeds.
Suitable for
 Drilling holes for faucets, shower fixtures and other sanitary installations
 Creating openings in porcelain and ceramic tiles during tile installation
 Plumbing penetrations where a clean, large-diameter hole in tile or porcelain stoneware is required
 Workshop use on drill presses for controlled, perpendicular drilling
Key specifications
 Cutting diameter: 53 mm
 Tip type: diamond-coated rim (open-center or continuous rim design)
 Material compatibility: hard ceramic, porcelain stoneware, glazed tiles
 Recommended operation: wet drilling with water cooling
 Tool compatibility: rotary drills and drill presses at low speed
How to use
Secure the workpiece to prevent movement and mark the drilling point. Fit the diamond drill bit into the drill chuck and ensure it is tightened correctly. Begin drilling at low speed, keeping the bit perpendicular to the surface. Apply light to moderate pressure and use a continuous flow of water to cool the bit and flush debris from the hole. If using a hand-held rotary drill, consider a guide or template to maintain alignment. Pause periodically to allow cooling and clear slurry, and continue until the hole is complete.
Usage recommendations
Use low rotational speed and steady, light pressure to avoid glazing the diamond tip. Maintain a constant supply of water to the cutting area to reduce heat and prolong bit life. For best results on large-diameter holes, perform drilling on a drill press where possible and avoid excessive lateral force to prevent tile cracking.
