Angle grinder - 9" (230mm)

The 9' (230mm) angle grinder is a large, capable angle grinder that is designed to tackle more challenging angle grinding jobs. These tools are designed to make deep cuts and therefore are useful tools for those that work with stone regularly. However, 9' angle grinders are also designed to cut and grind metal and other materials. Typically, the larger the blade, the slower it wears out, so these 9' grinders tend to be good tools for heavy-duty, frequent work.

• Disc diameter is the key choice to make when selecting an angle grinder. They range in disc diameter size from 4' (100mm) - 9' (230mm) with the 4.1/2' (115mm) & 9' (230mm) grinders being the most popular choices. Smaller grinders rotate the discs at a higher speed. 9' is one of the most popular disc diameter choices.

• Choosing your power source: The first choice is between a mains (110v or 240v) or a cordless tool. 240v tools are used with normal mains power whilst 110v tools are used on construction sites for safety reasons.
• With regards to cordless (battery powered) tools there are a variety of chemical types; Li-ion is the latest technology, prior to that it was Ni-MH and Ni-Cad was the original. The higher the Ah (Ampere hours) the longer the interval between charges; the fewer times you recharge a battery the longer it will last. Some cordless tools can also come without batteries - sometimes referred to as naked, bare units or body only. These tools are supplied without a battery or charger and more often than not without any accessories; as a result they are significantly cheaper in price.
