Diamond drill bit for porcelain stoneware GRAPHITE 60 mm TOP-57H295

The Diamond drill bit for porcelain stoneware GRAPHITE 60 mm TOP-57H295 is a diamond-tipped hole saw designed for cutting precise circular openings in dense ceramic and porcelain surfaces. Created for hard glazed tiles and porcelain stoneware, the bit is suitable for both dry and wet drilling methods and fits standard drill rigs and drill guides. Its 60 mm diameter makes it appropriate for creating holes for sinks, pipes, fixtures and other penetrations where a clean, accurate edge is required.

Advantages

The diamond cutting edge ensures efficient material removal and a long tool life when used on hard ceramic and porcelain. The construction provides stable rotation and reduced chipping around the hole perimeter, delivering accurate circular cuts. Compatibility with wet and dry drilling allows flexibility for different working conditions and helps control dust and cooling when required. The bit is designed to mount on commonly used drills and guides for controlled, repeatable hole-making.

Suitable for

• Drilling holes in glazed ceramic tiles and porcelain stoneware
• Cutting openings for sinks, faucets and plumbing penetrations
• Tile installations where precise circular holes are required
• Use with drill guides, tile jigs and standard hand drills or drill rigs

Key specifications

• Cutting diameter: 60 mm
• Tip type: diamond grit cutting edge
• Suitable materials: porcelain stoneware, glazed ceramic tiles
• Drilling mode: dry and wet capable
• Mounting: compatible with standard drill rigs and drill guides

How to use

Select an appropriate drill and guide for a 60 mm hole and secure the tile or workpiece to prevent slipping. If using dry drilling, apply light steady pressure and moderate speed to avoid overheating; if using wet drilling, ensure a constant water flow to cool the diamond edge and remove debris. Start drilling at a slight angle to establish a groove, then bring the bit to vertical once the cut is engaged. Maintain steady alignment and allow the bit to do the cutting—do not force excessive pressure. After completing the hole, slowly withdraw the bit while keeping rotation to reduce chipping at the exit side.

Usage recommendations

For best results on porcelain stoneware, prefer wet drilling where possible to extend tool life and improve dust control. Use a drill guide or tile jig to maintain perpendicular alignment and reduce the risk of cracking. Replace the bit if cutting becomes slow or irregular, and follow safety guidance including eye protection and appropriate gloves.
