Enjoy the flexibility and freedom offered by a cordless grinder from top brands such as Makita, Dewalt and Bosch. This tool offers multiple uses, including grinding, sanding, cutting and polishing. The cordless variety lets you work in tight spaces and gives you the opportunity to continue working even when an extension cord or source of power is not available. When choosing a cordless grinder or a cordless hand grinder, take care to find one that fits your needs. Not all grinders are alike; some are more appropriate for home use while other for professional use.
