Questions & Answers
Is this a slide switch or slide lock?
Asked by ToDoList October 31, 2018The switch is more of a slide lock. You have to push down and slide forward. It will not let you simply slide the switch on. Once it is on it remains on until you move the switch back, the switch does not return on its own.
Is there an accessory that I can use to utilize this as a car polisher?
Asked by Francisco September 24, 2018i do not think so it is a 4 1/2" grinder
I'm an electrician...don't know a lot about grinders. Do I want one with a "paddle switch" or one that "locks-on"?
Asked by Edco March 11, 2016As an electrician, I use mine primarily for cutting, so chose the lock-on.
Hello, do you sell EU version on the charher? 230Volt?

Why is this model not available in stores?
Asked by mjl June 13, 2016I'm assuming because for some reason people love that paddle switch...me on the other hand can't stand it. I ordered my on HDepot and got it 2 or 3 days later delivered free to my house.
Which model should i get?
Asked by Tileguy November 3, 2018Slide Switch all day, hands down(IMO) The paddle makes it a bit combersome if your working material in one hand grinder in the other etc. Also with the slide switch you can adjust your hands on the grinder for tight spaces/ accuracy/control and not have to worry about keeping the paddle pressed.
