## Long description

Diamond Drill Bit for Porcelain Stoneware GRAPHITE 50 mm is a cutting tool designed to create precise circular holes in porcelain stoneware, gres and other hard ceramic materials. The bit is intended for use with compatible rotary drills and drill stands and provides controlled penetration with minimal chipping when used correctly on brittle surfaces.
Advantages
The diamond cutting edge ensures effective abrasion of very hard ceramic surfaces, enabling accurate hole formation without excessive force. A 50 mm diameter offers a standard opening size for many plumbing and electrical fixtures. The tool is suitable for wet drilling to extend bit life and to reduce dust and heat during operation. Its design supports stable drilling performance when mounted in a drill or drill stand that maintains perpendicular alignment.
Suitable for
 Creating holes for plumbing fixtures such as faucets and drains in porcelain stoneware
 Cutting openings for electrical boxes and conduit through tiled surfaces
 Installing shower hardware, towel rails, and other fixtures into hard ceramic tiles
Key specifications
 Material type: diamond-cut cutting edge suitable for hard ceramics
 Intended materials: porcelain stoneware, gres and similar hard ceramic tiles
 Diameter: 50 mm
 Typical mounting: compatible with rotary drills and drill stands (ensure correct shank type for your drill)
 Recommended drilling method: wet drilling to cool the bit and reduce dust
How to use
Secure the workpiece and mark the hole center. Fit the drill bit into a compatible drill or drill stand, confirming the shank fits your tool. Start drilling at low speed and with light pressure to establish the initial groove, then maintain steady speed and moderate pressure. Apply water continuously or periodically to cool the cutting edge and remove debris. If using a handheld drill, keep the tool perpendicular to the surface to prevent unwanted chipping. Withdraw the bit occasionally to clear slurry and allow cooling.
Usage recommendations
Use appropriate personal protective equipment, including eye protection and a dust mask if dry drilling. Prefer wet drilling to prolong the bit life and to minimize dust and heat. Ensure the drill and stand are stable and that the bit is suitable for your drill’s shank system before operation.
