SKIL Power Tools dates back almost 100 years. The SkilSaw model 77 from 1937 is known as "the saw that built America," so it's safe to say that these tools have been used far and wide by handymen for decades. The current-production AG2902 20V cordless angle grinder is very durable and one of the most powerful such power tools you can get. It's got all of the useful features of a high-quality tool, and you can use it for a wide range of DIY home projects.

SKIL AG2902 20V 4-1/2 Inch Angle Grinder

The SKIL cordless angle grinder is the perfect tool for cutting, grinding, sanding, polishing, sharpening, and many other applications on all types of materials, including metal, plastic, wood, ceramics, and so on. It packs a powerful motor and many useful features, but the most significant benefit you get with this tool is portability.

You can take your work far away from a power outlet and get things done. It's a powerful tool that can change the way you look at cordless power tools forever.

What to Expect

The beauty of this cordless angle grinder is that it's suitable for beginners and professionals alike. It's an efficient 4-1/2" angle grinder designed for a wide range of applications. It's lightweight and sits well in hand. You’ll experience barely any fatigue even after using it for hours at a time.

There's a lot that you can do with it, including grinding off excess material after welding metal pipes, cutting metal sheets and PVC pipes, sharpening the blade on your lawnmower, cutting tiles, and so much more.

Even though the SKIL cordless angle grinder has some impressive features, it's got some downsides too. It can cope with some heavy-duty tasks but not for a long time. The RPM slows down under heavy load when grinding or cutting thick pieces of ceramics or metal. However, it won't stop or stall, but only slow down when pushed too hard.

Furthermore, you should avoid this tool if you have a lot of grinding to do. An angle grinder of this size is just not designed for that, and you can finish off the work much quicker with a larger corded grinder. When the battery indicator shows only two bars, the grinder will stop automatically after a few seconds of use.

The 2.0Ah battery is not enough for prolonged use, so you should perhaps get a 4.0Ah battery or bigger if you plan on using this angle grinder for large projects. It's also a bit heavy and bulky when compared to AC-powered grinders.

What's included?

Upon purchase, you will receive the SKIL AG2902 20V 4-1/2" angle grinder, but that's not all. The package also includes a universal grinding wheel ideal for grinding and cutting different materials.

The wrench storage handle works both as a handle and a holder for the wrench that's also included. Then, there is the grinding guard that prevents any debris or sparks from flying into you when you work. Finally, we have the 2.0Ah 20V battery and the charger.

Key features

  • 4-1/2 Inch
  • 3-position side handle
  • Soft start
  • No-load speed of up to 8,500 RPM
  • Lock-on switch
  • Metal gearbox

Features overview

The spindle lock allows you to change wheels quickly according to the task at hand. You can adjust the handle and the guard so you can use the angle grinder with both hands.

Many cordless tools lack the power needed to cope with heavy-duty professional applications, but not the SKIL angle grinder. The powerful motor can kick up speeds of up to 8,500 RPM, which is usually only available on corded tools. All of the materials used in the construction are high-grade and durable, a mix of ABS plastic and metal.

You can use this angle grinder to work on a variety of DIY projects quickly; just make sure that you charge the batteries before use. Other features like the soft start, fuel gauge, and fast charger work together to improve the precision of your work. It's possible to use the grinder without the side handle, but you can place it in one of three available positions for increased control on those demanding projects.

​Alternatives

If you’re looking for something you can use for big projects and on the job, you need something with a steady stream of power. By that, we mean that you need an AC-powered angle grinder that can keep working for hours at a time without running out of juice. The Metabo WP9-115 Angle Grinder is a good choice because it provides up to 10,500 RPM and it will help you finish off heavy-duty jobs much easier.

Conclusion

The SKIL 20V cordless angle grinder is the ideal tool for small DIY home improvement projects like cutting tiles, grinding rust off pipes, sanding old furniture, and similar tasks. You can pack it up and take it with you anywhere you want, but make sure you get a bigger battery or a spare if you plan on working far away from a power outlet.

You will get a lot of useful features designed to make most jobs more manageable, but some of the features you may find lacking in the long run. However, given that this power tool costs only a fraction of what many others are charging, it offers excellent value for the money, but you should stick with AC-powered devices for professional use on the construction site.
