Most used tool

Would Recommend

[This review was collected as part of a promotion.] I bought this awhile back for a special project. I have 2 other grinders of similar size, but this is usually my first choice. First, it is comfortable in my hand. I can't give the ergonomic specifics, because that is not what I do. I just use tools that feel comfortable to use, and balanced. Secondly, many of my projects require the use of more than one wheel. The Bosch button lock for the shaft really makes it fast and easy to change wheels w...

Very durable

Would Recommend

[This review was collected as part of a promotion.] I bought this Bosch angle grinder after a less expensive grinder “smoked” on me after less than 15 minutes of hard use. (I was removing old paint from the concrete floor of my porch). The Bosch grinder finished the job without a problem and has served me well for years. Definitely worth paying a little more to get a top quality tool.

Good power, short life with 4AH battery.

Would Recommend

[This review was collected as part of a promotion.] I have had this for a few months now and I am cutting and grinding regularly as I learn to weld. Building a shipping container home requires this skill. I have noticed that when you let the cutting blade do the work, it works well. I can still out with excessive pressure. I would say that to use this tool well, the 8AH battery is a must. The 4AH batteries just get blown through too quickly with any larger cutting or grinding jobs.
