Diamond hole saw for tiles Diam SX/M14 50 mm — DIAM DISX050N

Diamond hole saw for tiles Diam SX/M14 50 mm (model DISX050N) is a professional cutting tool engineered to drill precise 50 mm holes in ceramic and porcelain tiles and similar hard coverings. The cup features a diamond-segment cutting edge that provides durability and clean, chip-free results when used with compatible grinders. The tool uses an M14 threaded shank for direct attachment to angle grinders and is intended for plumbing, electrical and tiling installation tasks that require round openings in finished tile surfaces.

Advantages

The diamond-segment cutting edge ensures fast penetration and long life when cutting through glazed ceramic and porcelain. The M14 thread allows secure connection to standard angle grinders without additional adapters, providing stable rotation and consistent cutting performance. Designed for tile work, the cup minimises chipping and delivers a smooth hole edge suitable for pipe passes, fixture mounting and cable feeds. Its construction balances cutting efficiency with resistance to wear under typical jobsite conditions.

Suitable for

• Drilling 50 mm holes in ceramic wall tiles and porcelain tiles
• Creating openings for pipes and plumbing fittings through tiled surfaces
• Making cable and conduit entries for electrical installations
• Cutting holes for fixtures such as taps, valves or ventilation outlets

Key specifications

• Cutting diameter: 50 mm
• Cutting edge: diamond-segmented rim for hard tile materials
• Shank connection: M14 threaded mount for angle grinders
• Intended materials: glazed ceramic, porcelain and similar hard tiles
• Typical usage: wet or dry cutting depending on material and equipment recommendations

How to use

Securely fit the hole saw onto the angle grinder via the M14 thread and tighten according to the grinder manufacturer’s instructions. Mark the drill position on the tile, start at low speed to establish the cut and then increase speed steadily while maintaining light, even pressure. For best results on porcelain and highly glazed tiles, use coolant or periodic water application to reduce heat and prolong the diamond segment life; follow the safety and operating guidelines of the grinder. Support the tile from behind where possible to reduce vibration and avoid cracking.

Usage recommendations

For clean, durable holes: use steady speed, avoid excessive pressure, and apply water intermittently when permitted by the angle grinder. Wear appropriate eye, hand and respiratory protection when cutting tiles, and ensure the workpiece is firmly supported to prevent breakage.
