A basic, inexpensive Angle Grinder that has a unique feature.
RYOBI GIDDS2-3554575 6.5 Amp Angle Grinder With Twist Handle - http://amzn.to/2iDNDJ6 (AMAZON AFFILIATE LINK)
This angle grinder is a good option for a beginners unit. It is light weight, and easy to handle. It also comes with a twist handle that is very convenient to use in many different positions. If you think that your grinder is going to be harshly treated though, you may want to look at one of the 2 angle grinders listed below.
Here are 2 Angle Grinders that I have had and used. All of which I find to be very durable, and worth their price.
Makita GA4530X 4-1/2-Inch Angle Grinder with Grinding Wheels- http://amzn.to/2j4ZbE1 (AMAZON AFFILIATE LINK)
This Makita Grinder is their budget grinder. It's a bit lower powered than the more expensive Makita Angle Grinders, but it's a solid unit. I used this grinder in Chile, S.A. in the rain for a good two years, and it was going strong when I sold it.
Metabo W9-115 8.5 Amp 10,500 rpm Angle Grinder with Lock-On Sliding Switch, 4-1/2" - http://amzn.to/2hQJori (AMAZON AFFILIATE LINK)
While this Metabo is twice the price. It is a very solid unit, and I've used a number of them over the year in many different industries. While I can say all of them would endure the same abuse, I have seen them dropped and shatter the casing, and then turn right one and function like normal. So, if you have the money to spend on a good beginners angle grinder, this one is a good option in my mind. Metabo also offers more expensive versions with more power and features.
