One might think that we require different tools for cutting metal bars and plates, for flattening surfaces and for honing dull blades and knives. But there is a tool that can handle all of the operations mentioned above perfectly. The Ronix 3113 Mini Angle Grinder is an extremely handy power tool for cutting and grinding applications. This back-switch mini angle grinder has an 850W motor which is responsible for delivering a no-load speed of 12000 in RPM.
