PORTER-CABLE 20V MAX* Angle Grinder Tool, 4-1/2-Inch, Tool Only (PCC761B)

Great for my need

Does it have the power of a 110V machine? No. Does it have good power for a 20V machine? Yes, very good! Used mine for cutting to length an existing culvert that has been in the ground for years. The end had been run over and partially crushed, so it was not a simple cut. It involved a lot of crazy angles and layers of metal overlapping each other. It fully consumed one charge of a 4AH battery, but cut very well. The handles felt good and I never felt any lack of control or danger while using this tool. When an outlet is available, I will use my corded device, but this will get the job done in remote environments!

this was a good buy for me, I needed something I could out in the field because dropping a power cord is not always best when you have high traffic that can take a $100 power cord out. The batteries for this line are cheap and last for hours.

Very handy a lot of uses

I already had a prior 8-piece tool set (with the light) and added this, along with a fan and a brad nailer as well. Perfect addition to complete the set. All use the same battery system.

Easy to switch from a grinding disk to a abrasive metal cutting disk. It does seem to use battery capacity at a rapid rate. Keep high capacity batteries charged for continuous use.

UPDATE - Long story short: I contacted Porter-Cable and showed them a copy of this review. All I asked for was if I could send it to them to see if they could take a look at it and see if it was just a bad unit. Well... they offered to send me a new one - free of charge (didn't ask for the other one back). Really didn't expect that.Tried out the replacement unit and it seems to work just fine. Doesn't stop or bog down unless you really press into it (which is what I kind of expect as opposed to a corded unit). The battery life seems acceptable, as well.Bottom line: I must have just received a bad tool. I'm satisfied with the way it turned out and I'm updating my rating to 5 stars.First off: I'm a huge Porter-Cable fan. I've got 3 other 20v PC tools (drill, impact gun and reciprocating saw) and they all work fantastic. This thing though...Even when pushed moderately hard, it stalls and it absolutely chews through the battery life. My other tools? I can push them hard for quite some time before needing to change batteries.I don't know what the deal is with the angle grinder. I've had it too long to return it and it does have its uses (like if you want to cut an aluminum can in half - don't try to cut it into quarters - it won't make it, LOL). My experience doesn't seem to be typical, though. Maybe I got a bad one, or something.

Initially I purchased the drill and driver combo pack that Porter Cable sells which uses the same exact batteries as this grinder. First impressions is that the build feels solid and durable. If you have ever used a corded grinder / cut off tool you will know that they are normally very loud. This is much less noisy while running in comparison to the corded ones. The noise levels while grinding on metal would of course be the same. The detachable grip can be put in 3 different positions, left, right, and vertical for flexibility. This includes the grinder, 2 cutting disks, 1 grinding disk, a detachable hand grip, manual, and the tool needed to change the disks. It also comes with two different guards, one for grinding and one for cutting. As the description for the product states, it does not include a battery so you either need to buy it separately or use the ones you already have from one of their other 20-volt Max Lithium tools. The tool does have a safety lock switch which will stay in either the locked or unlocked position without having to continuously apply pressure.One of the features that my driver and drill have is a battery indicator at the base where the battery is attached so that you can get an idea of how much battery is remaining. This grinder does not have this but I personally do not think this is a deal breaker. The tool has an automatic shut off feature when the lithium battery is getting low so that you do not destroy the battery.Overall I am very satisfied with the purchase and would certainly recommend it for anyone needing a portable grinder / cut off tool.
