## Summary description

Diamond drill bit for porcelain stoneware, GRAPHITE, 73 mm diameter. Designed for drilling precise round holes in hard ceramic materials such as porcelain stoneware and glazed tiles. Features a diamond-coated cutting edge for durability and efficient cutting; suitable for use with water cooling and rotary drills. Ideal for plumbing, electrical installations and tile fitting.

## Long description

Diamond drill bit for porcelain stoneware GRAPHITE 73 mm is designed to cut precise round holes in hard ceramic materials such as porcelain stoneware and glazed tiles. The bit features a diamond-coated cutting edge that provides high wear resistance and consistent performance when used with water cooling. It is intended for use with rotary drills and drill stands capable of low-speed, steady operation to maintain cutting efficiency and prolong tool life.
Advantages
The diamond coating ensures efficient material removal and long service life compared with conventional carbide bits. The wide 73 mm diameter creates clean, round holes with minimal chipping when used correctly and with adequate cooling. Compatibility with water cooling reduces heat buildup, prevents glaze cracking and improves dust suppression. The design supports steady drilling at low to medium speeds, giving reliable results for installation and repair tasks.
Suitable for
 Drilling holes in porcelain stoneware tiles
 Creating access points for plumbing fixtures and pipework
 Making openings for electrical boxes and conduits in tiled surfaces
 Tile fitting and renovation projects requiring large round holes
Key specifications
 Diameter: 73 mm
 Cutting edge: diamond-coated
 Recommended cooling: water cooling
 Suitable materials: porcelain stoneware, glazed ceramic tiles
 Drive type: compatible with standard rotary drill chucks
 Intended speed: low to medium rotational speed
How to use
Secure the workpiece and mark the hole position. Fit the diamond bit into a compatible rotary drill or drill stand and set the drill to a low to medium speed. Start drilling with light pressure, keeping the bit perpendicular to the surface. Apply continuous water cooling to the cutting edge to reduce heat and remove debris; intermittent lifting can help clear slurry. Maintain steady, moderate pressure until the hole is complete, then withdraw the bit while the drill is still rotating to avoid snagging.
Usage recommendations
Use a drill stand or guide for best concentricity and to minimize chipping. Avoid high speeds and excessive pressure; ensure continuous water feed to extend bit life. Wear appropriate personal protective equipment such as eye protection and a dust mask when dry cutting or when slurry is present.
