For a detailed guide to the main selection criteria, read “how to choose an angle grinder”.
Corded angle grinders are mains-powered handheld tools used for cutting, grinding, cleaning, and surface preparation of metal, stone, concrete, and other suitable materials. This category covers corded electric models only and does not include cordless or pneumatic angle grinders. Suitability for a specific task also depends on the selected disc, accessory, and the manufacturer’s operating limits.
Common sizes such as 115, 125, 180, and 230 mm differ in potential cutting depth, tool size, and intended use. Use only a diameter approved by the manufacturer for the specific grinder. See “how to choose the correct disc diameter”.
Match motor power to the expected load and duration of use. The basic selection principles are covered in “how to choose tool power (W)”, while differences between professional and household use are explained in “differences between professional and household power tools”.
Maximum and, where applicable, minimum speed should suit the task and stay within the permitted operating speed of the accessory. For the meaning of this specification, see “what is rotational speed (RPM)”.
Variable speed is useful when the material, disc, or working method requires different rotational speeds. See “angle grinder speed control and how to choose it”.
Body shape, auxiliary-handle positions, balance, and weight affect control and comfort during longer work sessions. See “tool ergonomics, weight, and safety systems”.
Check disc diameter, bore size, mounting type, and the maximum permitted speed. Useful references are “how to check consumable compatibility with a tool” and “how to read disc markings”.
Install and secure the disc according to the manufacturer’s requirements. Incorrect mounting can damage the accessory or create a safety risk. See “how to install and replace an angle-grinder disc”.
Choose cutting, grinding, flap, or diamond consumables according to the workpiece material and the operation being performed. See “how to choose a consumable for the workpiece material” and “how to choose a consumable for the intended task”.
Use wet operation only when both the tool and the consumable are designed for that mode. See “dry vs wet operation: how to choose the correct method”.
Check the guard, restart protection, soft start, and other safety features provided on the specific model. See “tool safety systems and their purpose” and “how to use an angle grinder safely”.
At ToolsArmenia, corded angle grinders can be compared by disc diameter, power, rotational speed, speed control, ergonomics, and construction features so the tool can be matched to the actual task and accessory being used.
