## Summary description

Diamond drill bit for porcelain stoneware by GRAPHITE, 22 mm diameter (model 57H286). Designed for drilling hard ceramic materials such as gres and porcelain tile. Suitable for wet drilling with rotary drills or drill presses using diamond-segment cutting edge for precise, efficient holes. Ideal for plumbing, electrical installations and tile fitting where clean holes in dense tiles are required.

## Long description

Diamond drill bit for porcelain stoneware GRAPHITE 22 mm is a purpose-built cutting tool for drilling clean, accurate holes in hard ceramic materials such as gres and porcelain tile. The bit features a diamond-segment cutting edge designed to penetrate dense tile bodies with minimal chipping when used with wet drilling. It is intended for use with rotary drills and drill presses where controlled speed and coolant are applied to maintain cutting performance and tool life.
Advantages
The diamond cutting edge provides consistent cutting action on hard, vitrified surfaces and reduces the risk of cracking around the hole perimeter. Wet drilling lowers heat buildup and removes abrasive dust, extending the bit’s service life. The tool’s construction delivers stable, concentric drilling for accurate hole diameter and alignment, suitable for repeated use on porcelain stoneware and similar materials.
Suitable for
 Creating holes for plumbing fixtures through porcelain tile and gres
 Drilling openings for electrical boxes, conduits and cable passages in tiled walls
 Tile fitting tasks that require precise holes for anchors, bolts or pipework
 Workshop or on-site wet drilling with a drill press or handheld rotary drill
Key specifications
 Cutting diameter: 22 mm
 Cutting edge: diamond-segment for hard ceramic materials
 Recommended method: wet drilling to reduce heat and dust
 Compatible tools: rotary drills and drill presses with coolant or water feed
 Designed material: porcelain stoneware, gres and similar dense tiles
How to use
Mark the drilling position and secure the tile or workpiece to prevent movement. Start at low speed to establish the cutting groove, maintain a steady feed pressure and ensure a continuous water supply to the drilling area to cool the diamond tip and flush out debris. Apply moderate, even pressure without forcing the bit; increase speed slightly only when the hole is established. After drilling, clean the hole of slurry and inspect edges for any chips.
Usage recommendations
Use appropriate personal protective equipment, including eye protection and gloves. For best results on large-format or particularly hard tiles, consider using a drill guide or drill press to maintain perpendicularity. Replace the bit when cutting performance decreases noticeably to avoid damage to tiles and ensure consistent hole quality.
