## Description

The Bosch GWS9-45 4-1/2-in. Angle Grinder is a light, handy grinder with plenty of power – 8.5 amps and 11,000 RPM. It has direct-motor cooling, giving it higher overload capabilities, and it has directed air flow that diverts dust away from vital components. This grinder has a two-position side handle. It has a burst-protection quick toolless adjustable guard, a fast-change disc change and a large spindle lock. The Service Minderbrushes stop the grinder when preventative maintenance is required.

Review: I like it - Decided to pick up an extra grinder for masonry use. I originally got the GWS8-45 and wasn't happy with it, as it seemed to run a tad too hot amongst a few other things. I was worried at first this one would have too fat a grip, but it's about perfect. While it is a bit bigger than the GWS8-45 in the grip area, it seems to be easier to hold due to the shape and textures. I also like how this one is normal length and feels more balanced than the GWS8-45. It's also 8.5 amp which is a plus. The function of it is about typical of an angle grinder, I have no complaints so far. I've used it outside in high temperatures with moderate use and heat wasn't an issue, but the gear box does get hot; which seems typical of these Bosch grinders due to how they are setup inside. The spindle spins true and no abnormal vibrations with or without a new diamond blade. I find unlike the switch on the GWS8-45 (which seems to be easier to accidently set off even though it appears to be a thicker in size switch), only when gripping up very high, this grinder doesn't have that issue. The only con I can come up with is I wish the bottom cover/guard mount that seals the spindle, gears, etc.. inside, fit tighter around the screws or just in general sealed better. I notice that grease can slightly seep out over time or as it gets hotter. Not sure what the reasoning is behind that but I doubt it's too big of an issue. Overall I am pleased so far with the grinder and it performs as expected.

## Questions & Answers

**Q: Hello - is the dust collection accessory offered here in tandem purchase actually compatible wit this item? bosch seems to say not so. please clarify.**
A: If you are referring to the GA50DC, then NO.  Bosch specifically states (on its website) that it it is not compatible with the GWS9-45.  In fact, Bosch does not have ANY dust attachments that fit this grinder!  HOWEVER, if you read my review, I recommend two dust attactments that fit the GWS9-45 without any modifications (I have both of the attachments I recommend).

**Q: Is the arbor 5/8 -11?**
A: Thank you for your question. The GWS9-45 has a 5/8"-11 threading. If you have further questions please feel free to contact our Bosch Customer Service Representatives at 1-877-BOSCH-99 (1-877-267-2499).

**Q: Weight is listed as 2.9 lbs. In your dreams! What is the actual weight?**
A: 3.lbs

**Q: this grinder is of adjustable speeds?**
A: Thank you for the question. The GWS9-45 Angle Grinder doesn't feature a speed dial and only has on/off switch. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

### ⭐⭐⭐⭐ Dust Collection Accessories
*by M***L on September 28, 2018*

I purchased this for a master bathroom tile project... I have not had any issues with it. My only frustration was that Bosch chose not to create any dust collection attachments for this specific model-- and for that reason I give it 4 stars. BUT Good News... through trial and error, I finally found dust collection attachments that work with this angle grinder without modification. The following two Makita products fit this Bosch GWS9-45 4-1/2" Small Angle Grinder without any modifications: (1) Makita 196846-1 Dust Extracting Tuck Point Guard, 5" https://www.amazon.com/gp/product/B0042CD9TG/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 EDIT: This works like a charm! ZERO dust and the plunge cut & depth control adjustments are awesome. Worth the money if you screw up a DIY tile job (my first time) and need to replace a tile set too low. (2) Makita 195236-5 4-1/2-Inch - 5-Inch Dust Shroud https://www.amazon.com/gp/product/B004F5JCG4/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 Note: On the surface grinding Dust Shroud... you need to purchase a 4-inch Cup Wheel to use with it. Anything larger will extend beyond the removable section (for grinding flush against a vertical wall, baseboard, etc.) and may extend beyond the shroud height-wise as well (The Bosch 5" cup wheel I first purchased failed on both counts). With these Makita attachments I'm satisfied with the GWS9-45. Shame on Bosch for not making attachments for this product.
