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. Review: Nothing beats Bosch - We use Bosch for all of our grinding needs. We are an Historic Masonry repair company and use Bosch Grinders and Vacuum cleaners to extract the dust we create. They are rugged, reliable and longer lasting than any other brand. ## Features - POWERFUL MOTOR AND COMPACT TOOL: 8.5 amps and 11,000 rpm - DURABLE CARBON BRUSHES FOR EXTENDED LIFECarbon brushes for extended life - DIRECT-MOTOR COOLING FOR BETTER WORKLOAD - DIRECTED AIR FLOW DIVERTS DUST FROM VITAL COMPONENTS - BURST-PROTECTION ADJUSTABLE GUARD FOR USER PROTECTION - SERVICE MINDERBRUSHES - QUICK-CHANGE DISC CHANGE AND A LARGE SPINDLE LOCK - SIDE HANDLE ADJUSTS TO TWO POSITIONS ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01D4R1IMY | | Best Sellers Rank | #344,153 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #543 in Power Angle Grinders | | Brand Name | Bosch | | Color | Black | | Customer Reviews | 4.3 4.3 out of 5 stars (95) | | Global Trade Identification Number | 00000346479959 | | Included Components | Grinder, Auxillary Handle, Wheel Guard, Flange Kit, Spanner Wrench, Abrasive Wheel | | Item Dimensions L x W x H | 10.5"L x 5"W x 3"H | | Item Type Name | Corded Angle Grinders | | Item Weight | 2.9 Pounds | | Manufacturer | Bosch | | Manufacturer Warranty Description | Limited 1 Year | | Material Type | Metal, Plastic | | Maximum Rotational Speed | 11000 RPM | | Model Number | GWS9-45 | | Power Source | Corded Electric | | Style Name | Industrial | | UPC | 000346479959 | | Unit Count | 1.0 Count | | Voltage | 120 Volts | | Wattage | 240 watts | ## Product Details - **Brand:** Bosch - **Material:** Metal, Plastic - **Power Source:** Corded Electric - **Product Dimensions:** 10.5"L x 5"W x 3"H - **Style:** Industrial ## Images ![GWS9-45 4-1/2 In.

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.

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.

We are an Historic Masonry repair company and use Bosch Grinders and Vacuum cleaners to extract the dust we create. They are rugged, reliable and longer lasting than any other brand. ### ⭐⭐⭐⭐ 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. ## Frequently Bought Together - Bosch 4-1/2" Small Angle Grinder GWS9-45 - Bosch GA50DC Small Angle Grinder Dust Collection Attachment, 4-1/2" to 5" - BOSCH GWS8-45 4-1/2 Inch 7.5 Amp Angle Grinder with Lock-On Switch, Lightweight Design, and Durable Protection Guard for Metal and Concrete Grinding --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/26602665-gws9-45-4-1-2-in-angle-grinder](https://www.desertcart.ni/products/26602665-gws9-45-4-1-2-in-angle-grinder) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-04-23*
