Diamond Cutting Disc 125 x 22.2 mm, Polax — 125 mm diameter, 22.2 mm bore

Polax Diamond Cutting Disc 125 x 22.2 mm is a segmented diamond blade designed for precise cutting of hard construction materials. With a 125 mm diameter and a 22.2 mm bore, this cutting disc fits most angle grinders with a 125 mm wheel size and provides efficient, clean cuts in concrete, brick, natural stone and ceramic tiles. The construction of the rim and diamond grit aims to balance cutting speed with edge quality for renovation, masonry and general building work.

Advantages

The diamond-segmented rim delivers fast material removal while maintaining controlled dust generation and reduced chipping on brittle surfaces. The 125 mm diameter allows for portability and ease of handling in confined spaces. The 22.2 mm bore ensures secure mounting on standard 125 mm angle grinders. Overall, the disc offers consistent cut accuracy and long abrasive life under typical construction use.

Suitable for

• Cutting reinforced and unreinforced concrete
• Trimming and shaping brick and blockwork
• Cutting natural stone and pavers
• Cutting ceramic tiles and porcelain

Key specifications

• Diameter: 125 mm
• Bore (arbor) diameter: 22.2 mm
• Blade type: segmented diamond rim
• Intended tool: angle grinder with 125 mm wheel size
• Typical use: dry cutting (verify tool and local conditions before wet use)
• Material compatibility: concrete, brick, stone, ceramic

How to use

Mount the disc on an angle grinder with a matching 22.2 mm arbor and ensure the grinder is switched off and unplugged or its battery removed during fitting. Tighten the mounting flange securely and check that the blade spins freely without wobble before powering the tool. When cutting, use steady, even pressure and allow the diamonds to do the work—avoid forcing the blade. For best results, make multiple shallow passes rather than a single deep cut when working thick or reinforced materials. Follow the angle grinder manufacturer's safety instructions and wear appropriate personal protective equipment such as eye protection, hearing protection and respiratory protection.

Usage recommendations

Use the Polax 125 x 22.2 mm diamond cutting disc for controlled, short cuts and detailed trimming tasks in construction and renovation. For extended cutting sessions or reinforced concrete, consider allowing the disc to cool periodically and use water cooling only if the disc and tool are rated for wet cutting. Inspect the blade regularly for wear or damage and replace it when cutting performance decreases or damage is visible.
