Miter attachment RUBI PRO-EDGER for RUBI tile tools — suitable for ceramic and stone, weight 4.1 kg

The RUBI PRO-EDGER miter attachment is a professional accessory for RUBI tile tools, designed to cut and finish mitres and bevels on ceramic and natural or sintered stone tiles. Supplied as a single unit and weighing 4.1 kg, this accessory is intended for intensive use with mini-angle grinders (115 or 125) and enables accurate angled cuts and controlled edge finishing for corner joints, trims and detailed layouts. The PRO-EDGER includes a 45° diamond grinding wheel for work on tiles up to 20 mm thick and features sealed high-speed bearings and polyethylene skids to ensure smooth movement and prolonged service life.

Advantages

The RUBI PRO-EDGER is compatible with most mini-grinders on the market and secures to machines with an M14 threaded shaft and quick-release belt, offering stable fixation and reduced vibration. Its sealed bearing system protects internal components from dust generated during grinding, while the wear-resistant polyethylene skids provide consistent, low-friction guidance along the tile edge. A variety of dedicated diamond wheels allow blunt bevels (5 and 10 mm radii) and 45° miter cuts on pieces of different thicknesses, and the accessory can be adapted to a vacuum cleaner to reduce airborne dust during operation.

Suitable for

• Creating 45° mitre cuts on ceramic and natural/sintered stone tiles
• Bevelling tile edges with 5 mm and 10 mm radii
• Finishing tiles up to 15–20 mm thick (depending on wheel chosen)
• On-site tile trimming for corners, thresholds and detailed layouts

Key specifications

• Weight: 4.1 kg (unit)
• Compatibility: mini-angle grinders 115 or 125 mm (cable and battery)
• Recommended grinder body diameter: ≤100 mm for proper fixation
• Recommended motor power: ~850 W for best control under roughing
• Included grinding wheel: 45° diamond wheel for up to 20 mm thickness
• Bevel radii options available: 5 mm and 10 mm (with dedicated wheels)
• Sealed high-speed bearings to protect against dust
• Polyethylene skids for smooth edge guidance
• Adaptable to vacuum cleaner for reduced dust (ZERO-DUST compatibility)

How to use

Fit a compatible mini-angle grinder (115 or 125) to the RUBI PRO-EDGER by engaging the M14 threaded shaft and securing the quick-release belt. Select the appropriate RUBI diamond grinding wheel for the required operation (mitering or bevelling) and install it according to the wheel instructions. When working, use progressive grinding passes at increasing depths to obtain clean finishes and avoid overheating or overloading the wheel. Maintain steady, controlled movement along the tile edge with light to moderate pressure and let the wheel do the cutting. For intensive or prolonged use, check bearing seals and skids regularly for wear and ensure the grinder’s power and stability are adequate for the task.

Usage recommendations

For best results, use a grinder with approximately 850 W power and a machine body no larger than 100 mm in diameter to ensure correct fixation. Perform progressive passes at different depths for superior finishes and switch to the appropriate RUBI diamond wheel depending on tile thickness and the desired bevel radius. Connect a vacuum cleaner for dust extraction to maintain a cleaner work environment and prolong the life of bearings and wheels.
