## Description

The Bosch GA50DC Dust Collection Attachment works with most Bosch 4-1/2 In. and 5 In. small angle grinders. The attachment can be part of the end-to-end Bosch PRO+GUARD™ Protection System, along with attachments, dust extractor and respiration protection (to be used as a basic summary; always use products in accordance with the ownerʼs manual and OSHA Rule 1926.1153 Table 1). The dust attachment has a single-screw depth adjustment to adjust it to the desired depth of cut. It has a large, durable foot plate, which greatly increases stability for clean, accurate cuts. The attachment is compatible with 4-1/2 In. and 5 In. small angle grinders: GWS10-45/P/PD, GWS18 V-45C/PC/PSC, GWS13-50/VS/VSP/P/PD, AG series and 1800 series grinders.

Review: Must have for indoor cutting - Bought this to attach to Bosch angle grinder that I put a cutting disc on to cut an old fiberglass shower pan. I had no ventilation and had it hooked up to a Bosch Dust Extractor. I have to say it worked great and collected probably 99% of the dust. There was nothing in the air and only the smell of the fiberglass being heated as it was cut. Worth every penny if you are doing indoor work and trying to cut back on dust. It fit the angle grinder perfectly and didn't add much weight. Great product.
Review: (Probably) unrivaled grinder dust collection - Fits my 5" Bosch grinder perfectly, and works pretty flawlessly, capturing between 90–98% of grinding dust, depending on the nature of the cut. It far outperformed my expectations in this regard. It also enhances safety. The only drawbacks are, primarily, that it limits the depth of cut and, second, that it can make the grinder a bit awkward to hold in certain positions. But most of the time these are very acceptable faults, as the near-total dust collection makes certain jobs possible (especially jobs indoors) that you just couldn't do otherwise. It's not cheap, especially compared to other dust hoods, but I can't imagine another one working as well as this. (I've never used another.) For cutting-grinding jobs; face-grinding unfortunately requires a dust shroud of a different design.

## Questions & Answers

**Q: will this fit my GWS8-45 grinder?**
A: No! I Purchased both GA50DC and GWS8-45 together based on this Q&A only to find out that the manufacturer's response was incorrect. I went to the site: https://www.boschtools.com/us/en/boschtools-ocs/grinder-attachments-ga50dc-138748-p/
and it states: "Toolless installation is compatible with 1800, AG, and GWS series 4.5 In. and 5 In. small angle grinders (excluding GWS8-45 and GWS9-45)." I've exchanged the GWS8-45 with the GWS13-50 (hasn't arrived yet). 

This listing for the GA50DC needs to be corrected!

**Q: How do I attach this to a vacuum?**
A: Hi there! The GA50DC Attachment connects to 1-1/4" and 1-1/2" hoses using adapters VAC002 and VAC024 or for 2-1/2" hoses you may use the VAC020 adapter. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

**Q: Anyone willing to post a how to video for installation? Surely I'm not the only one who can't figure it or decipher the diagrams!  New to angle grinde**
A: I could but I don't know how to

**Q: will it work on a millwakee  4.5 grinder?**
A: Thank you for your question. The GA50DC Dust Extraction Attachment is compatible with 1800, AG, and GWS series 4.5 In. and 5 In. small angle grinders (excluding GWS8-45 and GWS9-45) only. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

### ⭐⭐⭐ Well built but didn't work for my application
*by B***Y on January 14, 2026*

Thought this was going to be awesome but, not so much. I had to cut stucco out to install a patio cover on the back of my house and bought this to use on my bosch grinder. Ended up just free handing it because I couldn't get the depth of cut I needed. Seems to be well built.
