Diamond Cutting Disc Distar 125 x 2.2/1.3 x 12 x 22.23 Maestro H12 for Angle Grinder

Diamond cutting disc Distar Maestro H12 125 x 2.2/1.3 x 12 x 22.23 mm is a purpose-built abrasive wheel for angle grinders. The disc has a diamond cutting edge designed to provide efficient, controlled cutting of hard materials commonly encountered in construction and renovation jobs. Its dimensions are compatible with standard 125 mm grinders featuring a 22.23 mm arbor, making it a practical choice for professional and DIY tasks that require precision cutting.

Advantages

The Maestro H12 disc offers high cutting speed and consistent performance when working with hard materials due to its diamond abrasive composition. Its segmented design improves cooling and debris removal during cutting, which reduces overheating and extends usable life. The disc's defined thickness and bore ensure stable mounting and reduced vibration, contributing to cleaner, more accurate cuts.

Suitable for

• Ceramic tiles and porcelain
• Natural stone and granite
• Concrete and reinforced concrete (light cutting and shaping)
• Masonry elements and paving stones
• Renovation tasks requiring controlled, precise cuts

How to use

Mount the Distar Maestro H12 disc on a compatible 125 mm angle grinder with a 22.23 mm arbor, ensuring the wheel is correctly seated and the flange is tightened according to the grinder manufacturer's instructions. Use appropriate feed pressure—steady and even—to avoid clogging and overheating. Allow the disc to reach cutting speed before contacting the workpiece and maintain a consistent cutting angle for a straight, controlled cut. Always stop the grinder and let the wheel come to a complete stop before setting it down.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves, hearing protection and respiratory protection when cutting dusty materials. For best results, use water cooling or intermittent cutting on very hard or brittle materials to reduce dust and heat. Inspect the disc before each use for damage or excessive wear and replace if the cutting performance deteriorates or segments become loose.
