Diamond Cutting Disc AWTools 125 x 22.2 mm (AW44125) — full continuous rim for cutting

AWTools diamond cutting disc 125 x 22.2 mm (full continuous rim) is a thin, precisely manufactured blade intended for clean, low-chipping cuts in tile, ceramic, natural stone and similar hard materials. The continuous diamond edge delivers smooth finishing along cut lines and reduces the need for secondary grinding. The disc is compatible with angle grinders that accept a 22.2 mm bore and is suitable for both professional tradespeople and informed DIY users who need controlled, accurate cuts.

Advantages

The continuous rim construction provides an even cutting surface that minimizes chipping and produces smooth edges without serrated marks. Diamond abrasive composition ensures consistent cutting performance and longer life compared with non-diamond blades when used on appropriate materials. The standard 125 mm diameter and 22.2 mm arbor make this disc widely compatible with common angle grinders, enabling straightforward mounting and stable operation during use.

Suitable for

• Cutting ceramic and porcelain tiles with minimal chipping
• Trimming and shaping natural stone such as marble and granite (wet or dry depending on tool and technique)
• Cutting engineered stone and similar hard building materials
• Precision tile work for bathrooms, kitchens and facades

Key specifications

• Diameter: 125 mm
• Bore (arbor) size: 22.2 mm
• Edge type: Full continuous diamond rim
• Primary use: Cutting tile, ceramic, stone and similar hard materials
• Typical tool compatibility: Standard 125 mm angle grinders

How to use

Securely fit the disc to an angle grinder that accepts a 22.2 mm arbor and ensure the tool is disconnected from power during mounting. When cutting, hold the tool steady and use a controlled, even feed rate to avoid overheating and to achieve the smoothest edge. For many materials, cutting with a light, steady pressure and allowing the diamond edge to do the work reduces chipping and extends disc life. Depending on the material and cutter design, using water cooling or periodic pauses to let the blade cool can improve performance and lifespan.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and respiratory protection when cutting. Match the disc to the material being cut and follow the grinder manufacturer's speed and safety instructions. For best results on delicate tiles, consider making a shallow scoring pass before completing the full-depth cut.
