## Long description

Diamond core drill bit for porcelain stoneware GRAPHITE 44 mm 57H292 is a wet-use cutting tool designed for creating precise round openings in hard ceramic and gres tiles. The bit has a 44 mm cutting diameter and a diamond-segmented cutting edge optimized for fast penetration and clean hole edges when used with water cooling. It is suitable for handheld drills or drill rigs when combined with the appropriate adapter and stable drilling conditions.
Advantages
This diamond drill bit delivers accurate, circular holes with minimal chipping on glazed and unglazed porcelain stoneware. The diamond segments maintain cutting efficiency over repeated use while water cooling reduces heat and prolongs service life. The 44 mm diameter provides a standard size for plumbing and electrical installations, and compatibility with common adapters makes the bit versatile for different drilling setups.
Suitable for
 Drilling holes for plumbing fixtures through porcelain stoneware and hard ceramic tiles
 Creating openings for electrical conduits and outlet boxes in tiled surfaces
 Installing fittings such as taps, thermostats or shower fixtures that require clean round holes
 Use with handheld drills or drill stands when wet drilling methods are applied
Key specifications
 Cutting diameter: 44 mm
 Intended material: porcelain stoneware (gres) and hard ceramic tiles
 Cutting edge: diamond-segmented rim for wet drilling
 Recommended cooling: continuous water supply for wet drilling
 Drive type: cylindrical shank compatible with common adapters for drill chucks and rigs
How to use
Secure the workpiece and mark the drilling position. Fit the drill bit into the drill chuck or adapter and ensure a firm connection. Start at low speed to establish the cutting groove, apply steady light pressure and maintain a constant water flow to cool the cutting edge and remove debris. Increase speed moderately once the diamond segments have engaged, and avoid excessive axial force to prevent cracking. After reaching the required depth, withdraw the bit while keeping water flow active to clear slurry.
Usage recommendations
Use appropriate personal protective equipment, including eye protection and gloves. For best results, use a drill stand or guide to keep the bit perpendicular to the tile surface. Avoid dry drilling on porcelain stoneware. Replace the bit when cutting performance declines noticeably to maintain clean hole quality.
