## Summary description

Diamond drill bit 32 mm by GRAPHITE (model 57H288) designed for drilling porcelain stoneware and hard ceramics. Features a diamond-cutting edge for efficient, precise holes in dense materials.

## Long description

Diamond drill bit 32 mm by GRAPHITE (model 57H288) is engineered for creating clean, precise holes in porcelain stoneware and other hard ceramics. The bit features a diamond-cutting edge designed to penetrate dense, glazed surfaces with reduced chipping and improved hole quality. It is suitable for use with rotary drills and drill stands when installing plumbing fixtures, electrical fittings or any application that requires accurate circular perforations in tile and gres.
Advantages
The diamond-cutting rim ensures effective cutting on very hard and abrasive materials, delivering neat edges and minimizing surface damage. The 32 mm diameter provides a large, uniform opening for pipes, conduits or anchor fittings. Its construction allows stable operation in both handheld rotary drills and drill presses, offering consistent performance and longer service life compared with conventional carbide bits when used on ceramic surfaces.
Suitable for (tasks / use cases)
 Drilling holes in porcelain stoneware and glazed ceramic tiles
 Creating openings for plumbing pipes and fixtures
 Preparing holes for electrical conduits and wall-mounted fittings
 Use with drill stands for precise perpendicular holes
Key specifications
 Cutting edge: diamond-segment rim for hard ceramics
 Diameter: 32 mm
 Recommended use: porcelain stoneware, glazed tiles, gres
 Compatible tools: rotary drills and drill stands
 Application: wet or dry drilling depending on tool and material
How to use
Mark the drilling position and secure the workpiece to prevent movement. Start at low speed to establish the hole, then apply steady pressure while increasing speed as appropriate for the drill and material. Use a drill stand or guide for perpendicular holes and to improve accuracy. Cooling with water is recommended for prolonged drilling sessions or when using higher speeds; this reduces heat build-up and preserves the diamond cutting surface. After finishing, clean the hole and inspect edges for any required finishing.
Usage recommendations
Use steady, moderate pressure and avoid excessive side loads. For best results on porcelain stoneware, use intermittent water cooling to extend tool life and maintain cutting efficiency. When possible, start drilling with a pilot mark or a small guide hole to prevent bit walking on glazed surfaces.
