Description

When you need a tough angle grinder that’s streamlined with modern features, easy to use, and can get into tight spaces - grab the Worx 20V 4-1/2” Cordless Brushless Angle Grinder. 8500 rpm means you’ll have the force to take on heavy jobs like grinding metal, cutting tile, paving, and routing out mortar. The sleek design gives you dexterity for detailed jobs like sanding and polishing. This grinder is cordless, and only 4.5 lbs., so you can twist and turn into tighter spaces without worrying about tangling up a cord. The secure grip is designed to give you control, and the 2 position auxiliary handle lets you change your attack angle depending on the job. This grinder is driven by a brushless motor, which runs faster, longer, uses less power, and has a longer life than tools that utilize a motor designed around a brush. The anti- kickback technology shuts the grinder down when sensors detect a jam, so it’s easier to operate. It’s part of the PowerShare family of 20V and 40V power and garden tools, so you can grow your tool collection while saving money on batteries. This model is the bare tool only. 20V PowerShare battery and charger sold separately.

  • Cordless Worx grinder
I have been looking for a go to cordless grinder for quick jobs and it works very. It will use alot of battery depending on the brand. But definitely gets the job done for its price line. 3 year limited warranty is a nice feature as well.

  • Nice light weight
This is a nice light weight grinder, it comes with a grinding wheel but you need to order cutting discs like I did because most of the work I will be doing calls for cutting off metal. Cut off wheels are easy to find for this grinder so there's no problem it's a worx tool share battery so that's great and the battery last a good amount of time depending on what you're cutting and how hard you press straining the motor, ... show more

  • Good tool I have 3 Worx tools and they all perform well
I like Worx tools but the slide switch is sticky and difficult to lock in, while cutting the tool shuts down with the slightest catch in the material being cut. just have to adjust my speed when cutting soft material. I'm hoping the switch will loosen up after more usage.

  • Outstanding convenience
For light home construction and demolition it's the ticket ! Being battery powered I was concerned about whether it would have enough cutting power and for long enough. It does ! Short work on wood and soft metals so far. The down side is that I can see how bicycle, motorcycle and scooter thefts are much easier to do now. ... show more
