Description

RIDGID introduces the R86047 18V 4-1/2 in. Paddle Switch Angle Grinder Kit. RIDGID’S brushless motor technology delivers maximum performance and longer runtime. The powerful brushless motor in this grinder delivers up to 25% more power than its predecessor model (R86042B), with 9,000 RPM. The ergonomic paddle switch design makes using this tool for extended periods of time easier and more comfortable. Also, with tool-free wheel and guard adjustment, users can make fast and frequent accessory changes to maximize productivity and minimize downtime. Using an electronic break mechanism, the wheel quickly stops rotating as the user lets go of the paddle switch. As always, the RIDGID 18V Paddle Switch Angle Grinder is 100% compatible with all RIDGID 18V batteries. The R86047 Grinder includes the grinder, a type 27 grinding wheel, guard, auxiliary handle, R840040 18V 4.0 Ah MAX Output Battery, R86093 18V Charger and Operator's Manual.

  • Just a great tool
I'd you know Ridged, you know quality. I've always used this brand of tool for many years and still no complaints. Not cheap but their is a reason for that. Works the way you want a cordless tool to work.

  • Love rigid tools
Rigid, what more do I need to say still using my miter saw I bought in 2005.

  • Husband Approved
My husband said it's a great metal cutter. Good grinder tool for all sorts of projects. I had asked him to cut a recycled corrugated metal for my chicken coop and the job was done with ease!

  • Works well
Had been eyeing this for ao g time to go with the rest of my Ridged tools. Just not sure why it says not to use cupped discs?

  • Doesn't work
The first time I went to use the unit, it immediately powered off. Got sent a bad unit and doesnt appear they refurbished it!

Great tool

  • doesn't work with type 1 disc
I assumed it would work with either type 1 or 27 discs (cutting or grinding) and it only works with grinding. Other than that, it looks great, service was quick. So, this company gets a 5 but ridgid gets a 2.
