By FAR the Best Angle Grinders Yet: Bosch, Ridgid & DeWALT Flexvolting it Up

On todays episode we test some of the most request cordless 4.5" to 5" angle grinder from our viewers, the all new Bosch GWS18V-10N, Ridgid Octane vs the Brushless R86047B & DeWALT Flexvolt Advantage DCG416. Really impressed with some of these later offerings and the direction things are going here. More to come!

As always, the creator of this channel works in product development for Astro Tools, who don't make cordless angle grinders but it's worth knowing, always consider multiple sources when looking at a tool!

Thank you! Vibration is massively under-rated. You don't realize how much better a tool can be until you have a really smooth one for the same job.

I own the dcg418 6” FV model and use it nearly every day at work. I can say I don’t notice any cutoff and I’ve used it for 2 years, cutting, grinding steel and piping. If I have enough batteries i hardly every pick a corded one over it. I have no complaints

Got a Bosch GWS 18V-15 SC, strong smooth, has 3 different speeds, a vibration sensor that shuts off if the grinder vibrates too much, and shuts off by sudden movements like from kick back.

Makes me glad I chose my Ridgid angle grinder

I actually used it at work and blew my boss away with how fast it cut without stress

With that being said that DeWalt is absolutely insane but I'm not regretting my purchase

[Holledel]

I really like my Bosch tools. Even the freak is great within reason ( 1/2” or less bolts) and the free battery promotion is awesome

[Troyvidihoo]

Delighted to see the Ridgid models did like I expected them to. Kudos to Josh who obviously has more influence than me! Having switched to from Bosch to ridgid long ago mostly because of battery prices I don't regret it I'll still take the Ridgids over the bosch, especially considering I have lifetime warranty on these Ridgid batteries. I can add that from my own experience to eat after hour battery does definitely perform stronger and longer, and I've used them through several charge cycles without stopping never had one quit on me! Bridget just released at 12 amp hour battery I would love to see you testes again with that! Great video I really enjoyed it!

Testing with a load on the disk for vibration is important too. Some tools have enough gearbox play that they vibrate different when under load than no load

[Greasemonkey]

I own the DCG614, I’m in industrial repair and do a ton of cutting bearings off large fan shafts. With a cutoff wheel, (side load) the battery certainly runs short. With a flap wheel, you can push as hard as you want and grind long periods. I typically just use my 60v 6” Dewalt for large bearing cuts.

I'm on Ridgid platform and have been avoiding cordless grinders the same way I do cordless circ and recip saws for lack of power vs their corded options, but you've got my attention enough with the grinder to give it a try for the smaller, quick jobs.
Great review, thanks for sharing.

Oh my, this and project farm are having such an impact in my budget for DIY tools projects. Great content! Thanks!

[evilv]

I like that you know what emissivity is and how to adapt to it, and avoid error with the tape. It was a trick that i was shown years ago in a thermal imaging seminar. Most people are not aware of that and state erroneous information because of it. Good job!

[Shorty_Lickens]

This has nothing to do with your test, but Bosch is still one of the few companies selling compact 12 volt tools. I just got a small grinder from them and it works great if you need something to fit in an inconvenient place, like an engine block or behind your HVAC.

[robertmalecha]

Would like to see how the Dewalt power detect compared against the flex volt advantage.

[mikluck]

Have you guys considered doing an overall brand to brand comparison? Meaning: if I were looking to get into a new battery platform, which one fares the best over all the tools you guys have tested? Thanks for all the great content.

[YankeeCherokee]

So glad you tested the Dewalt Flex! I knew it was a monster. The Flex batteries seem to have overheating issues, especially 9ah and up.
The chainsaw has the same issue of seemingly overheating for no reason. Makes me nervous about commiting to that line.

[chrisstennett]

I bought the Bosch 2 days before viewing this video after owning a DeWalt for 5 years. $149 with 4 amp batter and charger at Lowe’s

If you like the locking ring on the Bosch, check out their X-Lock system. Like their SDS system on rotary hammers and jigsaws, and Starlock on multitools (co-development with Fein), it makes the old systems look horribly cumbersome and slow. The BiTurbo/ProFactor grinder tested here is also available with X-Lock here in Europe. Makita has also started to sell X-Lock grinders and accessories. I've been using the system for a while now and wouldn't want to go back from click-and-go to unwinding by hand. It's extremely fast and foolproof.

[Mrsmith]

I have a 60v dewalt grinder and it acts similar to this one. It will run like crazy with near corded power for a while then seems like It steps down into a reduced power mode. Switching batteries even if their not drained usually gets it out but not always.

[engineer_alv]

I appreciate your effort on bringing some very thoughtful and detailed testing to the table.

Surprising results. I came surprised on how the Ridgid proved more powerful than the Milwaukee but the small price difference, less vibration and more expansive lineup would still gravitate me towards team red. I owned the 2880-20 which looks almost the same as the 2888-20, just curious to see how it'd stack up.

But I'm also very interested on seeing some entries from Metabo HPT, Flex and the top dog PROFACTOR from Bosch: GWS18V-13CN.

I’d love to see the bosch biturbo tested too
