Bosch Angle Grinders - The Choice of the Professional?

For many years Bosch have produced high end professional angle grinders. They come with many disc capacities but the common sizes are 230mm, 180mm, 125mm, 115mm and 100mm.

The current professional angle grinder range includes the little GWS850, the popular GWS6-115 and the monster GWS22-230LVI. The angle grinder is quite a versatile tool with applications such as cutting, grinding, stripping, de-burring and polishing. They also come with some very neat features now such as kickback stop and vibration control.

The Bosch Pro Team has this machine on the list of tools that are tested by professional tradesmen and the results are just in from the 1st of the testers, Furniture Manufacturer, Benjamin Jemison. Read the full report below.

What are your experiences of the Bosch Angle Grinders? Do you agree with what Benjamin has to say? Are there other brands you also like or prefer? What are you using the tools for? What do you think of the new features and technology such as kickback stop, vibration control, SDS disc change or restart protection? Let us know your feelings in the comments box, thanks.

Here's Benjamins full report:

1. For which purposes did you use this tool?

Cutting radiator grilles, Cutting tonk strip, de-burring rough cuts and Sizing hanging rail.

2. How do you rate the performance of this tool in day-to-day use?

This grinder is excellent for use in the workshop, not too big and more power than you can shake a stick at! When cutting vast amounts of brass plated steel tonk, its rpm does not even dip, cutting through it like a hot knife through butter. Previous to this grinder, I have been using a small 4 grinder, which struggled and took a lot of time. Also the larger diameter, gives the disk a longer life time, which is ideal when repeat cutting.

3. Which feature of the tool impressed you the most, why was this?

The best feature of the grinder is definitely the dead-mans handle trigger. No matter how you hold the grinder, be it flat or on its side, it is very easy to use, either with your thumb or index finger, not too hard to push, and easy to hold in place. Also, if you were to drop, or slip off the trigger, the disk would grind to a halt, avoiding what could have been a serious injury. Very well thought about. Unlike the small grinder we have, which has a lockable on switch, which if dropped could end in a bad way.

4. How do you feel about the overall design of the tool features e.g. weight, power, speed, charge time etc?

It is a very comfortable tool to use, fits perfectly in my hands any way. Be it quite heavy to pickup with one hand, very front heavy (very well made though!), however, when using it, supporting the tool with 2 hands, it is VERY well balanced! Ever so easy to use. Changing the disks is also very easy to do, finally a spindle lock that just works!

5. Were your expectations of the tool met?

My expectations were exceeded; the grinder has taken every thing I have thrown at it with ease. Yet another fantastic Blue Bosch product.

6. Please summarise the overall experience that you had with the tool and any further comments;

Overall I have had an excellent experience whilst using the grinder, saving me time on what used to be a slow process. I am very much looking forward to using it on up coming personal automotive projects in which I am sure it will excel once again. Only little niggle I have is that there is no real tidy way of wrapping the tool up. I personally refuse to wind the cable around the body as it coils up, and takes a very long time to wrap up/unwrap. I have worked out a way to wrap it along the length from the butt to the secondary handle; however it does not always stay there. It would have been nice to see a cable retainer or clip. Otherwise very happy! I would like to thank Bosch for letting me test their tool; its been an experience and a valuable asset to my already large Bosch tool kit!
