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 SKIL AG2902 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 reconsider this cordless angle grinder if you have a lot of arduous grinding to do on a construction site. A cordless angle grinder like the SKIL AG2902 is more suitable for lighter DIY grinding tasks. That said, it will have no trouble cutting through threaded bar or angle iron, just don't expect it to ravage a steel beam or a thick steel plate. 

The 2.0Ah battery is really not enough for prolonged use, so if you're planning on making the most out of the SKIL AG2902, you should perhaps consider getting the 4.0Ah battery. The larger battery capacity will permit you to challenge tasks of the more demanding variety without power sully restrictions.

Lastly, one negative about the SKIL AG2902 is the overall weight and structure. It is quite heavy at 5.6 lbs and rather bulky when compared to some other cordless angle grinders or 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. The SKIL AG2902 also utilizes their famed PWRJump fast charger system and the batteries are fitted with a USB power adapter, so you can jump-start your phone or any other USB powered device if need be. 

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.

How to use

The SKIL AG2902 is really the definition of pug-in-play angle grinder. Simply snap the 20V 2.0Ah lithium-ion battery in and get to cutting threaded bar or or angle iron with ease. Changing discs with the AG2902 is a breeze and you can utilize the on-tool wrench that is conveniently located in grinders side handle.

Alternatives

If you’re looking for an angle grinder that will allow you to tackle bigger professional type projects, you might need something with a bit more power than what the SKIL AG2902 has to offer. 

The PORTER-CABLE PCC761B 20V MAX Angle Grinder is a good choice because it provides up to 8,500 RPM. In terms of power, the PCC761B is somewhat comparable to high-powered corded angle grinders. The Porter-Cable PCC761B also possesses a comfortable 3-position side handle that provides greater control when operating the grinder in more strenuous conditions. 

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.
