Diamond turbo grinding disc GRAPHITE 57H890 125x22.2x5 mm for angle grinder

The Diamond turbo grinding disc GRAPHITE 125 x 22.2 x 5 mm is a rotary abrasive accessory designed for use with angle grinders. Its turbo rim profile combines continuous segments with serrated edges to increase cutting speed and material removal while maintaining a controlled cutting line. The disc is suitable for work on hard materials such as ceramics, porcelain, natural stone and tiles, and can be used for both wet and dry operations depending on the working conditions and tool setup.

Advantages

The turbo rim geometry provides faster cutting and more aggressive material removal than standard continuous rims, reducing work time on thick or dense surfaces. The diamond abrasive layer is bonded for durability and consistent performance over repeated cuts. A standard 22.2 mm bore ensures compatibility with most common angle grinders, and the 5 mm rim width balances cutting depth with disc stability during operation.

Suitable for

• Cutting and grinding ceramic tiles and porcelain
• Shaping and trimming natural stone and engineered stone
• Surface preparation and chamfering of floor and wall tiles
• Wet and dry cutting tasks with appropriate tool and safety measures

Key specifications

• Bore diameter: 22.2 mm
• Rim thickness: 5 mm
• Rim type: turbo diamond rim for faster cutting
• Suitable materials: ceramics, porcelain, tiles, natural stone
• Use mode: wet and dry use (depending on conditions)

How to use

Mount the disc on an angle grinder with a matching 22.2 mm arbor and ensure the locking flange is correctly tightened according to the tool manufacturer's instructions. Select appropriate rotational speed and feed rate for the material being worked; allow the disc to reach full speed before contacting the workpiece. For wet cutting, supply a steady water flow to reduce dust and heat build-up; for dry cutting, use dust extraction and take frequent breaks to avoid overheating. Always verify the disc condition before use and replace it when the diamond layer is worn or the rim is damaged.

Usage recommendations

Use appropriate personal protective equipment including eye protection, respiratory protection and gloves. For best results on porcelain and dense stone, use steady, moderate pressure and avoid forcing the disc through the material. When switching between wet and dry operation, follow the tool and disc manufacturer's guidelines and ensure the disc is dry and free of debris before dry use to minimize imbalance.
