Is this brushless ?
Asked by: Joe
Thank you for your question. No, the 9557NB 4-1/2" Angle Grinder, with AC/DC Switch is not brushless. For a brushless option, please see the XAG11T 18-Volt LXT Lithium-Ion Brushless Cordless 4-1/2 / 5 in. Paddle Switch Cut-Off/Angle Grinder Kit, 5.0Ah.

7.5 Amp Corded 4-1/2 in. Easy Wheel Change Compact Angle Grinder with Grinding Wheel, Wheel Guard and Side Handle is rated 4.3 out of 5 by 188.

I prefer the on/off switch over the paddle switch. if your main job with this is grinding only then the type of the switch does not really matter, but for cutting on/off one is much more convenient. BTW its very easy to turn on or off, I dont understand ppl complaining about it being hard to turn on, all you gotta do is push it forward from the very back of the button and its on, you can hold it like that or push down and lock it on.

The new one replaced my last Makita 4" angle grinder that finally gave up after 25 years, yes 25. The only item I would like to see changed is the on off lock switch. With heavy welding gloves it's a bit cumbersome to turn on and off because of the way the lock works on the slide switch. With thinner gloves works great but have to fumble around a bit when locking it while welding and grinding. Other than this, I would highly recommend it. I would recommend the additional wrench which used to come with the older ones be supplied in the box, should the lock button fail used for holding the shaft it would be nice to have handy for changing wheels. Shipping and delivery was great from Home Depot and actually showed up a day earlier than expected, price was good and quality seems excellent.
