When looking to purchase an angle grinder for concrete or other uses it is important to decide on the features that you will be wanting.  Some of the most important things to look at are whether or not you want portable or plugged in and the amperage needed for the jobs you want to tackle.

Comfort is often a consideration as well.  Safety such as having a guard and a slide switch is often extremely important to ensure the safe operation of the grinder.  Bonus features such as dust ejection and cooling may also be an important aspect for those who will be using the tool extensively and for dusty projects such as cutting concrete or tile.

For budgeting reasons, you may want to purchase an all-in-one set that gives you everything you need to get started.   To determine the best product to suit your needs you would first need to assess the job to be done.  Is it close to a power outlet? Would you need it to be battery operated? Will a portable angle grinder give you enough power for what you need to do? 

Test out the grip on some of the machines to get an idea of comfort and weight. You might also want to ensure the machine offers safety precautions such as a safety guard. Is it going to be a dusty job? Dust ejection may be a big factor in that case.  Once you know what you need for the job, shopping for an angle grinder is that much simpler.
