Diamond core drill bit Smart SM-25-060 for porcelain stoneware, Ø 6.0 mm

The Diamond core drill bit Smart SM-25-060 for porcelain stoneware, Ø 6.0 mm, is designed for making precise round holes in hard ceramic surfaces such as gres and porcelain tiles. The bit has a diamond cutting edge engineered to cut through dense glazed and vitrified tiles while maintaining hole accuracy and minimizing chipping when used with appropriate technique and equipment. It is suitable for professional tile installers and DIY users who need clean, reliable holes for fixtures, plumbing penetrations, or electrical fittings.

Advantages

The diamond cutting edge provides high wear resistance and extended life when drilling porcelain stoneware. Its 6.0 mm diameter delivers accurate, repeatable hole sizes for fittings and anchors. The bit is compatible with both wet and dry drilling methods depending on the drilling tool and cooling arrangements, helping control heat build-up and reducing the risk of surface damage. The compact core profile facilitates precise positioning and reduced material waste around the hole.

Suitable for

• Drilling clean holes in porcelain and vitrified tiles (gres)
• Creating openings for pipes, cables, and fasteners in tiled surfaces
• Tile installation, repair and renovation work
• DIY projects requiring accurate small-diameter tile holes

Key specifications

• Diameter: 6.0 mm
• Cutting material: diamond edge suitable for hard ceramics
• Intended material: porcelain stoneware (gres) and similar dense tiles
• Drilling method: compatible with wet and dry drilling depending on equipment
• Core type: small-diameter core for precise holes

How to use

Mark the drilling position on the tile and secure the workpiece to prevent movement. When possible, start drilling at a low speed to establish the hole and then increase speed as appropriate for the tool and material. Use water cooling when compatible with your drill to extend bit life and reduce dust and heat; if dry drilling, follow the tool manufacturer's guidance for intermittent operation to avoid overheating. Apply steady, moderate pressure and avoid lateral force that could crack the tile. After completing the hole, clean debris from the core and inspect the hole edges for chipping.

Usage recommendations

For best results on porcelain stoneware, use a drill with adjustable speed and, where feasible, wet cooling to minimize heat and extend diamond life. Use a guide or template to ensure perpendicular drilling and protect the tile surface with tape or a sacrificial backing to reduce chipping at the exit side.
