Diamond hole saw for tiles Diam SX/M14 45 mm

The Diamond hole saw for tiles Diam SX/M14 45 mm is a purpose-built cutting tool for creating clean, circular openings in ceramic and porcelain tiles. Designed for use with M14-mounted drills and angle grinders, it delivers a 45 mm cutting diameter suitable for plumbing fixtures, electrical boxes and other installations where precise tile penetration is required. The diamond-segment rim provides effective cutting performance on hard tile surfaces and allows for both wet and dry cutting depending on the tool and working method.

Advantages

The diamond-segment edge ensures consistent cutting speed and longer life compared with standard abrasive hole saws when working on hard glazed and porcelain tiles. Its M14 mounting makes it compatible with a wide range of angle grinders and rotary tools, simplifying tool selection for professionals. The 45 mm diameter offers a standard size for many installation tasks and permits accurate, round holes with minimal chipping when used correctly. The design supports both wet and dry operation, enabling flexible use on-site.

Suitable for

• Drilling holes for pipes and plumbing fixtures through ceramic and porcelain tiles
• Creating openings for electrical boxes, conduit and switches in tiled surfaces
• Tile trimming and penetrations during bathroom and kitchen renovation
• Fieldwork where compatibility with M14-mounted angle grinders or drills is required

Key specifications

• Cutting diameter: 45 mm
• Cutting edge: diamond-segment rim for hard tile materials
• Mount type: M14 thread for angle grinders and compatible rotary tools
• Suitable materials: glazed ceramic, porcelain and similar hard tiles
• Operation: suitable for wet or dry cutting depending on tool and technique

How to use

Mark the centre of the required hole on the tile and secure the workpiece to prevent movement. Fit the hole saw to an M14-compatible angle grinder or a drill with an appropriate adapter. For best results on large-format or porcelain tiles, start at low speed to establish a pilot groove and apply light, steady pressure. Use water lubrication for wet cutting to reduce dust and heat, or use short, controlled passes when cutting dry to avoid overheating. After cutting, clean the rim and the hole to remove debris before finishing the tile installation.

Usage recommendations

Use personal protective equipment such as eye protection, gloves and respiratory protection when dry cutting. For improved tool life and cleaner holes, wet cutting with continuous or intermittent water feed is recommended when the work environment and tool permit. Avoid excessive lateral force and allow the diamond segments to cut at their own rate to minimize chipping and prolong the diamond rim life.
