## Summary description

Diamond cylindrical drill bit by GRAPHITE for drilling glass and glazed surfaces, diameter 10 mm (model 57H280). Designed for precise hole-making in glass, ceramic tiles and glazed materials; suitable for use with low to medium drilling speeds and water cooling. Commonly used for installation, tile work and glazing repairs.

## Long description

Diamond cylindrical drill bit GRAPHITE 10 mm is designed for drilling precise holes in glass, glazed ceramics and similar brittle materials. The 10 mm diameter and diamond-coated cylindrical tip provide accurate cutting with reduced chipping when used with appropriate drilling technique. Intended for use at low to medium speeds and with water cooling to extend tool life and maintain hole quality.
Advantages
The diamond coating on the cylindrical head ensures high hardness and wear resistance, enabling consistent performance when working with glass and glazed surfaces. The 10 mm size gives a balance between hole precision and cutting stability, while the cylindrical shape supports straight, controlled drilling. When used with coolant and moderate speed settings, the bit produces clean edges and reduces the risk of cracking.
Suitable for
Drilling holes in glass panes and mirrors
Creating openings in glazed ceramic tiles and sanitaryware
Installing fittings that require precise round holes in brittle surfaces
Repairing glazing and tile fixtures where controlled material removal is needed
Key specifications
Cutting material: diamond-coated cylindrical tip
Shank type: cylindrical
Nominal diameter: 10 mm
Recommended speed: low to medium RPM
Cooling: water cooling recommended
Primary application materials: glass, glazed ceramics, tiles
How to use
Secure the workpiece to prevent movement and mark the drilling point. Use a drill or drill press with a steady, low to medium rotational speed. Apply water continuously to the drilling area to cool the diamond tip and remove debris; a gentle downward pressure and avoidance of sudden lateral forces will reduce chipping. For best results, start with a shallow pilot notch or use a guide to stabilize the bit on smooth surfaces, then proceed gradually until the hole is complete.
Usage recommendations
Use appropriate eye protection and gloves. Maintain continuous water flow during drilling to preserve the diamond coating and prevent overheating. Avoid excessive feed force and high RPMs to limit the risk of cracking fragile materials. Inspect the bit for wear before use and replace when cutting performance declines.
