Great Tool for the Home or Business!
I purchased this Dewalt Grinder to assist with sharpening my riding mower blades. I have a lot of Dewalt cordless equipment so I wanted to make good use of the batteries I have already. First, I will say this grinder has some serious torque. Just by activating the trigger you feel the tool twist in your hand from the torque. Pros: Great Power Ease of accessing tight spots Ease of changing disc Grinder guard is easily adjusted without tools 3 year limited warranty Comes with battery and charger(starter kit) 5 inch grinding wheel included 8000 rpm motor Compatible with Dewalt batteries Cons: Weight of 6 pounds I used this grinder to sharpen my mower blades and as you can see it did a great job. It was easy to control and the brake for the disc slowed the grinder pad soon after I released the trigger. This will prevent unwanted damage and injury. This is a tool you didn't know you needed, until you don't have it. I have attached photos of the mower blades. This tool is a beast and has multiple uses! If you find this review helpful, I would appreciate giving it a like and helpful check!

Constantly Jamming
I've had constant trouble with this gun jamming, no matter what type of nail and no matter what type of material I'm trying to nail. I wish I hadn't bought this gun, it's been nothing but trouble. The latest issue is trying to nail with 2 1/2" hot dipped galvanized nails into fiberboard trim (see example pic). After failing outside, I took the gun inside and tried it to see what was happening, the nails don't even penetrated through the fiber board. Should have bought a pneumatic gun.

    Excellent quality and portable too. Used this circular saw actually at home depot for wood that didn't fit in my suv. Just measure what you will need before shopping then use it in the parking lot. Strong and battery life is excellent.

      Be careful when purchasing this battery. I purchased with the Dewalt DCD791P1 (Brushless XR 20v drill/driver). This battery was listed on HD's site as option. The battery has the same model number as the battery that came with the drill, but did not seat properly on the charger and lock in place. The pin design on this battery was different than the battery that came with the drill. It would not charge at all because the design differences. Date codes on both drill battery and this battery were both 2020. The drill battery has a set of 6 independent slots for the pins in the middle (picture). The battery that HD had for this one has 5 taller slots like the 2 outer ones in my picture. Another indicator is the black piece in the grooved area. Battery supplied with drill is as shown, but the battery I received was all yellow.

        I am very happy with the tool itself, but Home Depot shouldn’t deliver power tools in the DeWalt box, the likelihood of it getting stolen was astronomical, with that said, I shop Home Depot regularly, and will continue, but when customers order expensive things, you should put them in a generic box, that won’t make it as much of a target please

        1 DOA, 1 lasted 5 mins. (5Ah NOT 6Ah)
        I received my two 5Ah batteries and tried to charge them. 1 would never take a charge and was dead on arrival. The other took a partial charge and ran one of my tools for about 4-5 minutes. After that it would not take a charge. I could maybe understand 1 failure, but 2 for 2 means a big design or manufacturing problem (both?) for DeWalt. I tried 2 different DeWalt chargers.

          When my son was young I had a basketball hop installed in our yard. The installer not only cemented the post into the ground he poured cement into the post. I wanted to remove it but couldn't decide which power tool to purchase for the project. I originally decided on a reciprocating saw but decided it wouldn't cut the post as close to the ground as this DeWALT Grinder. This tool did the job perfectly. However, the grinding disc supplied with the tool wasn't quite suitable to the job so I purchased a Rigid Metal Cutting Diamond Blade. This combination was perfect for the project and did exactly what I wanted. It not only cut through the steel but the cement as well. I would highly recommend this tool as well as DeWALT tools as well!
