    Mighty Seven (M7) cordless grinders deliver the performance of a professional grinder without depending on a compressor or a cable. Built on a shared 18V Li-ion platform with a brushless motor, they handle both rough cutting and fine finishing anywhere — in a mobile service, on-site installation, or wherever an air supply simply isn't available.

    Brushless technology in practice

    The brushless motor has no carbon brushes that would rub and burn out — it heats up less, lasts longer, and gets more work out of a single battery. The electronics monitor the speed under load, so the grinder doesn't lose cutting power even under pressure into the material, similar to a quality mains-powered grinder.

    One battery for the whole workshop

    Because M7 cordless tools share the same 18V Li-ion battery, one set of batteries powers the grinder, the saw, the screwdriver, and garden equipment. You don't have to buy batteries for each machine separately — this significantly reduces the overall cost of equipment.

    Main reasons to choose Mighty Seven (M7) cordless grinders:

    • ✔ Mobility – work anywhere, without a hose or an extension cord.
    • ✔ Mains-level power from a battery – the brushless motor maintains speed even under pressure.
    • ✔ Shared batteries – one battery for the entire M7 range.
    • ✔ Low maintenance – no carbon brushes, less servicing, and a longer lifespan.
    Mascot Ventilek advises

    VENTILEK’S TIP:

    Cordless means freedom — no hose dragging behind you, no cable mess around the workshop. If you already have M7 batteries for your impact wrench, the grinder will use them too. Tip: for paint finishing use the random orbital DOS-501, for quick cutting use the angle grinder DG-501.
