Product information

Description

Diamond drill bit GRAPHITE 6 mm (57H278) is designed for drilling porcelain stoneware and other hard ceramic materials. The 6 mm diameter creates precise, clean holes suitable for tiles, sanitary ceramics and construction fittings. The drill bit is compatible with standard rotary hand drills and drill stands when used at low speed with water cooling to reduce heat and prolong cutting edge life.

Advantages

The tool delivers accurate hole placement with minimal chipping due to its diamond cutting edge adapted for dense, low-porosity ceramics. Its narrow 6 mm profile enables fine-diameter drilling for fixtures and fittings while maintaining stability in the bore. When used with appropriate cooling and speed control, the bit offers extended service life and consistent performance across repeated operations.

Suitable for

  • Drilling porcelain stoneware (gres) tiles
  • Creating holes in sanitary ceramics and bathroom fixtures
  • Preparing openings for anchors, dowels and small fittings in ceramic cladding
  • Workshop or on-site tile installation where precise small-diameter holes are required

Key specifications

  • Cutting material: diamond grit on the cutting edge suitable for hard ceramics
  • Nominal diameter: 6 mm for precise small holes
  • Shank type: standard cylindrical shank compatible with common hand drills and drill stands
  • Recommended drilling method: low rotational speed with continuous water cooling to minimize overheating

How to use

Secure the workpiece and mark the drilling position. Fit the drill bit into a compatible drill chuck and set the drill to a low speed. Apply light, steady pressure and start drilling; maintain a perpendicular angle to the tile surface. Use a steady stream of water to cool the cutting edge and remove debris. For increased stability and precision, consider using a drill stand or a guide fixture. Withdraw the bit periodically to clear slurry and prevent clogging.

Usage recommendations

Use low RPM and continuous water cooling when drilling porcelain stoneware. Avoid excessive pressure and overheating to preserve the diamond cutting surface. For best results, practice on a sample tile to determine optimal speed and feed for your specific material and equipment.
