## Long description

Diamond drill bit Smart SM-25-550 for porcelain 55 mm cutting diameter is a specialized core bit designed for making clean, accurate holes in porcelain and hard ceramic materials. The bit features a diamond cutting edge that enables precise removal of material with reduced chipping. It is intended for wet drilling and can be used with handheld drills or drill presses when a controlled, steady feed is applied. Typical applications include sanitaryware and tile installations where a neat circular opening is required.
Advantages
The diamond cutting edge provides high cutting performance on hard glazed surfaces and dense porcelain, helping to minimize cracking and edge damage. A 55 mm cutting diameter produces a large, precise hole suitable for fixtures and pipe passages. Designed for wet drilling, the bit benefits from coolant to extend diamond life and reduce heat buildup during use. Compatibility with both handheld drills and drill presses allows flexible use on-site or in workshop settings.
Suitable for
Drilling holes in porcelain sanitaryware (sinks, basins, toilets)
Creating openings in ceramic and porcelain tiles
Installing fixtures that require precise circular holes (pipes, fittings)
Wet drilling operations to reduce dust and overheating
Key specifications
Cutting diameter: 55 mm
Cutting material: diamond edge designed for hard ceramics and porcelain
Intended drilling method: wet drilling
Compatible tools: handheld drills and drill presses
How to use
Mount the diamond drill bit securely in the drill chuck and set up a stable workpiece. Use continuous water flow or an appropriate coolant to keep the cutting edge submerged and to remove debris. Start drilling at low speed and apply light, steady pressure; do not force the bit. For handheld use, maintain a perpendicular angle to the surface and ensure the drill is stable to prevent walking. For deeper holes, periodically withdraw the bit to allow water and debris to clear and to cool the cutting edge.
Usage recommendations
Use with a water supply or coolant for prolonged tool life and improved hole quality. Select a drill with variable speed control and avoid high speeds that generate excessive heat. On delicate or thin tiles, consider supporting the opposite side to reduce vibration and risk of cracking.
