20-Volt MAX Cordless Brushless 4-1/2 to 5 in. Paddle Switch Angle Grinder with FLEXVOLT ADVANTAGE (Tool Only)

The 48 inch brush cutter that works off the PTO of my tractor takes quite a beating in normal use which means the blades need grinding in order to keep them semi-sharp. The cord on my older grinder gets in the way. The spinning grind wheel cut the cord with just minimal contact. Today, a new DeWalt DCG416 cordless grinder with a brushless motor is replacing the old one. This new DeWalt grinder accepts either 4-1/2" or 5" Type 27 wheels. The Guard that comes with the DCG416 is movable by hand when turning it clockwise. The guard release lever must be depressed to move it counter-clockwise. Performing the counter-clockwise operation has caused the guard to disconnect. To be safe, the battery must be removed while re-attaching the guard. The paddle switch and auxiliary handle make for a comfortable feel. A different guard, Type 1/41 (must be purchased separately) is required if cutting wheels are to be used.

I received the grinder in its box without any other packaging. There was a tear in the cardboard but the contents were apparently all there. The grinder comes with instructions, handle and an Allen wrench, to use with the large knurled spindle clamp nut. The hex indentations in the nut are about 1/10” deep, so there isn’t much engagement area for the Allen wrench. The uncushioned screw on plastic handle which can be attached to the left or the right side of the grinder head. It has a paddle type switch with small lever safety. This is a Flexvolt Advantage tool which is brushless and apparently has a brake. The tool takes about 1 second to come to a complete stop after releasing the switch. It has a quick adjust blade guard lever. I have a 5.0Ah DeWalt 20 volt XR battery to use with the grinder, but no Flexvolt batteries yet. A Flexvolt battery can apparently give the tool up to 54% more power than the standard battery. The grinder gets up to speed quickly and seems to have plenty of power. It has one speed. There’s a fine mesh air intake at the base near the battery and the cooling air exits at the tool head. It has a maximum of 1550 watt output and 9,000 rpm. Weight of the tool is 3.92 pounds. I can’t speak to longevity as I only just got it, but the tool seems well made, and has a 3 year warranty with 1 year free service and 90 day money back guarantee. The tool is made in China.

[This review was collected as part of a promotion.] I got this tool a few weeks ago and now that I have use it enough I only can say one thing There is no other brand that can deliver quality and price just right powerful cordless grinder that gets you all the juice from the 60v battery but also can use the 20v battery Flex volt machine that you can use any of the 60v battery or 20v battery but if you use the 60v it uses the full power from the 60v it gets heavier but it balances the weight and gives a better control to the machine and improves your cuts

[This review was collected as part of a promotion.] Being an amateur DIY'ist (is that what it's called?) and woodworker, I didn't think I would find many uses in my day-to-day for an angle grinder. After getting the 20V Max FLEXVOLT brushless angle grinder, I looked up some common uses, watched an online video or two, and got to work. First up, I decided to use it to sharpen some lawn mower blades. I HATE sharpening lawn mower blades. Prior to having this angle grinder, I would use a little attachment for my handheld powered multi-tool. Although easier than using a hand file, it was still obnoxious trying to use the cheap attachment and grinding stones and the results weren't all that great. I took a trip to the hardware store, bought a 40 grit flap disc, and a couple minutes later had 2 fully-sharpened mower blades. Super quick and easy! I will never sharpen mower blades a different way again. This angle grinder was very easy to setup as a beginner and had plenty of raw power; it's almost a little intimidating how much power this grinder puts out. The ergonomics are also very nice and the handle can be easily switched from left to right. I had no issues adjusting the tool-free guard or installing the cutting/grinding discs with the included allen key. I saw an online review of an older model which mentioned that the button that stops the disc from spinning was in a position that wasn't comfortable to get to without removing the handle. I'm happy to say that this model has that button installed on the top of the grinder and allows for much easier access. For my second use, I thought I'd give it a shot at cutting through a hardened steel chain that I wanted to cut in half to get an extra use out of (the original chain is far longer than what I needed it for). I placed the chain in a vice, installed a metal cut-off disc, and sliced through the chain without any issue. Now I have 2 security chains! As far as battery life goes, I had this grinder paired with a DeWalt 6 Ah FLEXVOLT battery. I had no issues with the small projects I used it for. I'm always impressed with DeWalt's cordless power tools in this regard. They're powerful, rugged, and easy on the eyes (I'm a sucker for the yellow and black). For the future, I plan on getting a wire brush disc to clean up the patina on an old and weathered axe. It could also use some sharpening. I have little doubt that the DeWalt 20V Max brushless angle grinder couldn't handle anything I throw at it. I look forward to the further uses I can find from this powerful tool!

[This review was collected as part of a promotion.] This angle grinder is awesome! It has many great features like the option of switching the handle from one side or the other this gives the option to use the tool weather your a lefty or a righty. The breaking system is a great feature that will help the user stay safe when working with the tool. The angle grinder feels lighter then the other angle grinders making it easier to hold. The paddle switch is very smooth!

[This review was collected as part of a promotion.] I work building ropes courses, so there is a lot of cutting thick bolts and cable. I have a Flexvolt 60v grinder but it can be a bit heavy to haul 50' in the air. This grinder has just as much power and battery life. I was able to work for 3 days cutting bolts and cable on one battery. I used it with a 20 volt battery and a Flexvolt battery. The Flexvolt definitely gives it some extra power. Dewalt has a winner with the Flexvolt advantage line of tools.

[This review was collected as part of a promotion.] By far one of the best grinders on the market! Very smooth while running it. There's a big difference when running a flexvolt battery compared to a regular 20v. It's also very quiet compared to a regular corded grinder.

This Angle Grinder by DEWALT is another tool that I need for my collection of cordeles tools, it really helps a lot for the kind of work I do, sometimes is really difficult to get extension cord long or even power for where I’m working this DEWLAT angle grinder makes my job so much easier, all I need is to make sure I have a couple of batteries charge, I try it with the 20V battery and the flex volt if you are going to use it for a long period, the lock mechanism for changing the blades is just is very safety, also has a break once you release the power . I really like it definitely I recommend this Dewalt angle grinder 100%

DEWALT 20-VOLT MAX LITHIUM ION CORDLESS BRUSHLESS 4-1/2 - 5 IN. PADDLE SWITCH ANGLE GRINDER WITH FLEXVOLT ADVANTAGE I’ve used this Dewalt grinder on a few thing. I’ve cut up pieces of tin roof. Steel bars from 1/2 to 3/4 inch. I’ve used a few flap disk and wire wheels. It’s been impressive for what I’ve done with it. I used it with the bigger 20v battery’s. If it gets better with a flexvolt battery I may never use my plug in grinder again. The braking is I nice feature. It stops spinning about a second after you let off the button. The grinder is comfortable to use and actually pretty light even with a the big 20v battery. Guard is easy and quick to adjust. Swapping the wheel or disc out is simple. It come with an Allen head for the tool It could use a way to attach the Allen head to the tool so it doesn’t get lost.

This is a really good angle grinder. It isn't too heavy, but isn't too light either. Only thing you need to do is screw in the handle and put a battery in it to go. The handle gives you the control you need to make sure you aren't swinging, but cutting or grinding in the place you need to be. So far this tool has done everything I have asked of it.
