Diamond cutting disc DNIPRO-M 125x2.0x22.2 mm for metal and stone

Diamond cutting disc DNIPRO-M 125x2.0x22.2 mm for metal and stone is a thin, precision cutting wheel designed for angle grinders with a 125 mm diameter mounting and a 22.2 mm bore. With a 2.0 mm cutting thickness and a segmented diamond rim, this disc is intended to deliver straight, accurate cuts through a variety of hard materials including metal, concrete, brick and natural stone. The design balances cutting speed and durability for renovation, construction and workshop tasks.

Advantages

The disc provides efficient material removal while maintaining a narrow kerf to minimize waste and reduce effort during cutting. A diamond abrasive rim ensures high wear resistance and consistent performance on abrasive materials. The 22.2 mm bore fits standard angle grinder flanges, allowing secure mounting and stable operation. The 2.0 mm thickness supports fast, precise cuts with less vibration compared to thicker wheels.

Suitable for

• Cutting steel and other ferrous metals with appropriate cooling or cutting technique
• Cutting concrete, brick and paving stones on construction and renovation sites
• Workshop tasks requiring straight, narrow cuts in mixed materials
• On-site repair and modification of metal profiles and stone elements

Key specifications

• Diameter: 125 mm
• Cutting thickness: 2.0 mm
• Bore diameter: 22.2 mm
• Abrasive type: diamond rim
• Intended materials: metal and stone (concrete, brick, natural stone)
• Typical tool compatibility: angle grinders with 125 mm discs

How to use

Mount the disc on an angle grinder that accepts 125 mm discs and a 22.2 mm arbor, ensuring the wheel is properly secured according to the tool manufacturer’s instructions. Use appropriate personal protective equipment including eye protection, gloves and hearing protection. For cutting metal, apply steady pressure and maintain a consistent feed rate; for stone and concrete, consider intermittent cutting and controlled speed to avoid overheating. Do not exceed the maximum RPM marked on the disc or the grinder. Inspect the disc for damage before each use and replace if any cracks or excessive wear are present.

Usage recommendations

For best results, select a cutting speed and feed appropriate to the material: slower feed and steady pressure for thick metal, moderate speed and intermittent passes for dense stone. Use water suppression only if the disc and tool permit wet cutting; otherwise, ensure adequate dust extraction and ventilation when cutting masonry or concrete.
