Mighty Seven Industrial Co., Ltd. has been manufacturing pneumatic and cordless tools since 1965 at its headquarters in Taiwan. M7 provides custom production (OEM) for a number of premium global brands — the technology you buy directly from M7 is often found under another logo at a significantly higher price.
You obtain parameters comparable to the premium Western competition at a considerably more favourable price, with a 24-month warranty and original spare parts in stock in the Czech Republic — no weeks of waiting for an order from abroad.
