Over the past several years we have seen some great leaps forward in cordless grinders. Until recently many would not even call them “cordless grinders” only “cordless cut-off” tools because they would stall almost instantly if you actually tried to grind with them. Thanks to the advances in brushless motors and new higher amperage 4Ah, 5Ah, 6Ah+ batteries we are now seeing cordless grinders start to outperform many corded models. If this trend continues and prices continue to come down we could see a big shift towards cordless grinders. For this comparison we are looking at the cordless brushless 18V grinders from Milwaukee, Makita and Metabo.
The goal of this test is to basically look at these 3 top grinders and compare how they perform in heavy applications, speed as well as battery life. Grinders are much tougher tools to compare side by side with stats because there are no torque ratings only RPMs which means very little without a solid motor behind it. Of course we will also look at costs, aerodynamic, safety features and other aspects of each tool. (more…)
