## Summary description

Diamond core drill bit for porcelain tiles (gres) with a 35 mm cutting diameter and M14 threaded shank. Designed for drilling precise holes in hard ceramic and porcelain surfaces; suitable for wet or dry drilling depending on tool and application. Used with angle grinders or compatible rotary tools that accept M14 fittings for tile installation, plumbing and electrical fittings.

## Long description

Diamond core drill bit for porcelain tiles 35 mm with M14 shank by Keltin is a purpose-built cutting tool for creating precise circular holes in hard ceramic and porcelain (gres) surfaces. The 35 mm cutting diameter and M14 threaded shank make it compatible with angle grinders and rotary tools that accept M14 fittings. The segmented diamond edge provides effective material removal and durability when used for installation of fixtures, plumbing penetrations or electrical outlets in tiled surfaces.
Advantages
The diamond cutting segments are engineered for long life on dense materials such as porcelain and gres, providing consistent cutting performance. The M14 threaded shank ensures firm attachment to compatible grinders and eliminates slip during operation. This core bit is suitable for both wet and dry drilling when matched with the correct tool and cooling approach, offering versatility across different jobsite conditions. The 35 mm diameter delivers a common hole size for many fittings while minimizing chipping on delicate glazed finishes when used with appropriate technique.
Suitable for
 Drilling holes for plumbing fixtures in porcelain and ceramic tiles
 Creating cable and conduit entries for electrical installations
 Installing wall-mounted fittings such as anchors and fasteners in tiled surfaces
 Making service access or inspection openings in tiled walls and floors
Key specifications
 Cutting diameter: 35 mm
 Shank type: M14 threaded shank for angle grinder/rotary tool attachment
 Cutting material: diamond segments suitable for hard ceramics and porcelain (gres)
 Recommended use: wet or dry drilling depending on tool and cooling
 Typical applications: tile penetration for plumbing, electrical and fixture installation
How to use
Secure the M14 shank into a compatible angle grinder or rotary tool and verify the attachment is tight before starting. Mark the drilling position on the tile and start at low speed to establish a guide groove, then increase speed as appropriate for the tool and material. For wet drilling, apply a steady supply of water to the cutting area to cool the diamond segments and remove debris. For dry drilling, follow the tool manufacturer's guidance on duty cycle and cooling pauses to avoid overheating. Maintain steady, moderate pressure—avoid forcing the bit—to reduce chipping and extend segment life.
Usage recommendations
Use appropriate personal protective equipment including safety glasses, gloves and hearing protection. When possible, prefer wet drilling for prolonged tool life and reduced dust; if dry drilling is necessary, work in short intervals and ensure good dust extraction to protect respiratory health. Inspect the cutting segments before use and replace the core bit if segments are excessively worn or damaged.
