Diamond Cutting Disc 3M EC-18 125×1.9×10×22.23 mm

Diamond Cutting Disc 3M EC-18 125×1.9×10×22.23 mm is a thin, precision cutting wheel intended for use with angle grinders. With a 1.9 mm cutting width and a diamond abrasive edge, this disc is engineered to deliver accurate, fast cuts in hard materials such as tile, stone and ceramics. The 125 mm diameter and 22.23 mm center bore suit common grinder flanges, while the segmented diamond rim provides controlled cutting performance and reduced chipping on fragile surfaces.

Advantages

The thin 1.9 mm kerf minimizes material loss and allows for narrow, accurate cuts. Diamond abrasive delivers high wear resistance and consistent cutting speed through hard masonry materials. The disc’s geometry and balanced construction reduce vibration and contribute to smoother operation on angle grinders. Its design helps limit chipping on tiles and ceramics, improving cut quality and reducing rework.

Suitable for

• Cutting ceramic tiles and porcelain
• Cutting natural stone and engineered stone
• Cutting masonry materials such as brick and concrete blocks (thin cuts)
• Precision trimming and fitting work in tiling and flooring installations

Key specifications

• Diameter: 125 mm
• Cutting width (kerf): 1.9 mm
• Arbor hole: 22.23 mm
• Rim type: Diamond abrasive edge
• Suitable tool: Angle grinder
• Typical applications: Tile, stone, ceramics

How to use

Mount the disc on a compatible angle grinder with a 22.23 mm arbor and ensure the flange and locking nut are correctly seated and tightened according to the grinder manufacturer’s instructions. Observe the disc rotation direction marked on the blade. Use steady, even feed pressure and avoid forcing the disc; let the diamond edge perform the cutting. For best results on tiles and ceramics, score and then complete the cut with smooth passes. Always allow the disc to cool between prolonged cuts to maintain cutting performance and life.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection, dust mask or respirator, and cut-resistant gloves. Secure the workpiece before cutting and work in a well-ventilated area or use dust extraction when possible. Match rotation speed and grinder size to the disc rating and follow the tool manufacturer’s safety limits.
