Yes Bosch makes or made good ones, the no tools needed blade change is good.
Bosch isn't exactly cheap.
The blades are more expensive then generic but they make up for it in quality they last.
And they seem to support their products with repair parts.
Dewalt well don't have much good to say about them may as well get it straight from HF and save some money.
The HF 4 1/4 inch angle grinder has out lived the Dewalt by over a year at a 1/3 of the price.
The Milwaukee on the other hand is worth the money.
