Diamond drill bit for porcelain stoneware GEKO 10 mm HEX

The Diamond drill bit for porcelain stoneware GEKO 10 mm HEX is a diamond-edged core bit designed for drilling clean, precise holes through hard glazed tiles and porcelain stoneware (gres). With a 10 mm cutting diameter and a HEX shank, this drill bit is made to work in impact-free rotary drills and drill presses commonly used for tile installation and sanitary or kitchen fittings. The diamond cutting edge improves wear resistance and maintains cutting performance when working with dense, glazed surfaces.

Advantages

The diamond edge gives consistent cutting performance and longer service life compared with standard carbide bits when used on hard glazed tiles and porcelain stoneware. The 10 mm diameter produces accurate holes for fixtures, anchors, and pipe pass-throughs, while the HEX shank ensures a secure grip in drill chucks and quick-change adapters. The design minimizes chipping on delicate glazed surfaces when operated without hammer action, helping preserve the finished appearance of tiles.

Suitable for

• Drilling holes in glazed ceramic tiles and porcelain stoneware (gres)
• Installing bathroom fixtures, taps, and shelving on tiled walls
• Creating openings for plumbing pipes and electrical conduits in tiled surfaces
• Use with impact-free rotary drills and tile drill presses

Key specifications

• Cutting diameter: 10 mm
• Tip material: diamond edge for hard glazed surfaces
• Shank type: HEX shank for secure engagement
• Intended materials: glazed ceramic tiles, porcelain stoneware (gres)
• Recommended drill mode: rotary (no hammer/impact)

How to use

Mark the drilling position on the tile and, if possible, use masking tape to reduce sliding. Fit the GEKO 10 mm HEX diamond drill bit into an impact-free rotary drill or drill press with a compatible chuck. Start drilling at low speed, applying steady, moderate pressure and allowing the diamond edge to cut without forcing. For deeper holes or prolonged drilling, withdraw occasionally to clear debris and, if appropriate for the drill and tile, cool the drill bit with water to reduce heat buildup. Finish the hole slowly to avoid chipping the glaze.

Usage recommendations

Use the drill bit only in rotary mode; do not engage hammer or impact settings. For best results on porcelain stoneware, maintain slow speeds, steady pressure and consider using water lubrication. Always wear appropriate eye protection and follow safe drilling practices when working with tiles.
