        East Coast Innovations Dia55 | GreenDonkey 55mm Diamond Holesaw

        The GreenDonkey 55mm Diamond Holesaw (Dia55) is purpose-built for cutting GPO openings in tiles. Designed to pair with GreenDonkey outlet templates, it provides a clean, fast alternative to traditional tile-cutting methods. This holesaw is ideal for electricians working on kitchens, bathrooms, and tiled commercial spaces.

        Simply mark your cut-out with the Green Donkey template, drill two angled half-holes using the Dia55, then complete the opening by linking the cuts with a diamond cutting disk on an angle grinder. The extended side slots allow waste to clear quickly, making the process clean and efficient with minimal risk of tile damage.

        GreenDonkey Dia55 Diamond Holesaw Features

        • 55mm size: Matches standard GPO cut-out height
        • Diamond cutting edge: Cuts cleanly through ceramic and porcelain tiles
        • Extended side slots: Allows fast waste removal while drilling
        • Grinder-compatible process: Link half-holes with a cutting disk to complete cut-out
        • Template-ready design: Pairs perfectly with GreenDonkey cut-out guides

        Where to Use the GreenDonkey Dia55 Holesaw

        • Tiled GPO installations: Clean and accurate cut-outs for power points
        • Bathroom and kitchen fit-offs: For a professional finish in hard surfaces
        • Residential and commercial jobs: Reliable tile-cutting with repeatable accuracy
