Angle Grinders

About Angle Grinders

Angle grinders handle cutting, grinding, polishing and surface prep with a single power head by swapping the wheel. The category spans compact 4.5-inch tools built for metalwork, tile cutting and weld cleanup all the way to heavy-duty models drawing over 1500 watts for high-volume stock removal. Prices run from roughly $20 for a no-frills corded 4.5-inch grinder to over $300 for a cordless combo kit with battery and charger included, giving buyers a wide band to match tool to budget. Power source is the first fork in the road. Corded models like the DEWALT DWE402 (1320 watts, 11000 RPM, $94.00) and the Makita 9557PBX1 (900 watts, 11000 RPM, $109.00) maintain full output for as long as you are working without any battery management. Cordless options run on major battery platforms: the DEWALT DCG413B operates on a 20-volt battery at 3450 RPM and $149.61, while the Milwaukee 2880-20 runs at 8500 RPM on an 18-volt M18 pack at $149.99. Pneumatic grinders like the AIRCAT 6280 (18000 RPM, 1.8 pounds, $105.63) are tailored for shops with existing compressed-air infrastructure. Motor wattage and disc size narrow the decision further. Most buyers doing light to medium metalwork, tile or masonry jobs will be well served by a 4.5-inch model in the 720 to 1320-watt range. More demanding applications such as removing heavy welds or cutting hardened steel call for higher wattage, as illustrated by the Makita GA7021 (1800 watts, 6000 RPM, 15.4 pounds, $209.00). Understanding those three variables, power source, wattage, and disc size, covers the vast majority of buying decisions in this category.
