Powerful, 10-Amp Motor for Dependability
Whether you're working in a granite shop, smoothing floor pavement, erasing graffiti, removing weather-worn paint, or cleaning surfaces, the 1773AK is up to the task, thanks to its powerful 10-amp motor that delivers 11,000 RPM. Bosch's trademarked Constant Response Circuitry maintains constant motor speed under even the toughest jobs, providing overload protection and delivering a reduced-torque soft start that safeguards your work surface.

For added safety, automatic restart protection guards against restart after a power failure, and it ensures that the tool is never powered on unless you need it to be. And a lock-on/lock-off switch lets you tackle extended-use applications comfortably.

Diamond Cup Wheels for Precision and Safety
Bosch diamond cup wheels, like the five-inch wheel included with the 1773AK, last longer, offer reliable performance, and provide safe grinder operation. Bosch diamond cup wheels are crafted with high-grade diamond segments, and they are manufactured using a process that includes 100-percent dynamic counterbalancing of every grinding head for comfortable, reliable, and vibration-free work.

The diamond cup wheels' five-hole dust extraction design provides an optimal combination of allowable airflow and material removal that complements the rest of the 1773AK's dust removal features.

Innovative Dust Management for Clean, Safe Operation
The 1773AK features a convenient dust extraction port and comes packaged with a vacuum adapter to help keep your work area clear, safe, and free of dust. This concrete grinder also boasts a specially designed head for surfacing applications, which combines with the Bosch diamond cup wheel to ensure clean, safe dust extraction that exceeds both UL and OSHA safety requirements.

The dust collection system also utilizes a replaceable brush ring to help you maintain dust-free working conditions over time.

Sealed Against Dust and Debris for a Long Life
With epoxy-coated field windings, a sealed switch, double-sealed ball bearings, and two lip-sealing rings to protect against dust contamination, the 1773AK is built to stand up to the toughest jobsite conditions.

For added convenience, the grinder's spindle lock allows for quick wheel changes on the job. And when preventive maintenance is required to keep your concrete surfacing grinder in top shape, the trademarked Service Minder light lets you know.

Practical, Ergonomic Design for Ease of Use
A slim, ergonomic barrel means you can grip the 1773AK comfortably and securely, even when you're removing mortar from a bathroom floor or working in another tight space. The grinder's wraparound auxiliary handle provides control from a variety of angles, and it offers multiple hand positions for decreased operator fatigue.

The 1773AK concrete surfacing grinder is backed by a one-year warranty, 30-day, money-back guarantee, and one-year service protection plan.

4.0 out of 5 stars Easy-to-use, finishing tool, July 24, 2004

Jerry Robison (Sunnyvale, CA USA) - See all my reviews

This review is from: Bosch 1773AK 5-Inch Concrete Surfacing Grinder (Tools & Home Improvement)

I do residential construction and was looking for equipment that can shape concrete foundations, piers and slabs. Although I already have a 4.5in angle grinder with a diamond cup, I was searching for something that would leave a smoother, flatter surface and would not put out clouds of harmful annoying dust. The Bosch 1773AK Concrete Surfacing Grinder is well designed and made from quality materials. It requires no skill to use. In fact, its boring. Just set it on top of a foundation wall or slab, apply a little pressure and drag it along at about 1/4in per second. The surface grinder has a dust removal port that mostly eliminates the dust clouds. An adapter (included) brings the diameter up to 1-1/4in and then another one on the vacuum hose (not included) allows connection to the 2-1/2in port on a Ridgid shop vac. Although the Bosch surface grinder functions correctly and does remove dust, I would call it strictly a surfacing tool rather than a grinder. Ironically, the equipment works best on surfaces that are already flat. This expensive, specialized tool leaves a flat, finished surface of exposed aggregate. It is for this specific task and does not replace the angle grinder. If I have to remove chunks, round corners or shape the material down to a somewhat flat surface, I go back to the angle grinder.

4.0 out of 5 stars Right tool for the job, May 17, 2006

This review is from: Bosch 1773AK 5-Inch Concrete Surfacing Grinder (Tools & Home Improvement)

I purchased the Bosch surfacing grinder to perform some floor preparation for a tile job. The concrete slab was cracked at one of the induced cracking points. One side of the crack was raised about 1/8 inch higher than the other side. The crack was near the door, and the height difference made it impossible to set the new tile so that the new tile height matched the old tile height, outside the room.

I used the Bosch surfacing grinder to level the crack along a 3 foot length of the crack. It work flawlessly. In about 15 minutes, the leveling job was done. The tiles line up perfectly, now. The grinder was used with a shop vac, and there was virtually no dust, until the shop vac filter got plugged.

One of the previous reviewers mentioned a problem with the circuit breaker tripping when the grinder is used. I also experienced this problem. It occurred to me that the shop vac was operating on the same circuit as the grinder. The combined current load exceeded the circuit breaker rating. I switched the shop vac to an outlet on a separate breaker, using an extension cord. This fixed the breaker tripping problem. If you have high powered stereo gear, other appliances, or heavy lighting loads on the same breaker as the grinder, the breaker will likely trip. Make sure to put the grinder on its own lightly loaded circuit.

Over the years, I have purchased several other Bosch tools from Amazon.com. I find Amazon's service to be good, and I think very highly of Bosch's tools. Bosch's Bulldog hammer drill, router, jig saw, and 1/4 sheet sander all exceeded my expectations for quality, durability, and value. The Bulldog is excellent for broken tile and thin-set removal, by the way. You wouldn't want to tear up flooring for an entire house using this thing. But for removing tiles in a bathroom or bedroom, the Bulldog is a great asset.

My only gripe for the concrete surfacing grinder is the price, and the price for alternate grinding wheels. Both seem a bit steep. There aren't that many choices out there, and I think Bosch plays this fact to their advantage. I would buy it again, though, in spite of the price. I dinged the product 1 star for the price. A Bosch 8.5A, 5 inch grinder is about $150. Add $20 for more amperage, and $75 for a grinding wheel and you're up to $245. I think this is the true dollar value for this tool, and I would give 5 stars if the price was in the $250 range.

06/13/06 Update: I ended up grinding about 30 linear feet of concrete cracks to achieve a smooth and level surface. The Bosch concrete surfacer performed flawlessly. It easily paid for itself on that one tile job. I also used it to remove old drywall mud from the slab. The residual drywall mud was left over from the initial house construction. The carpet guys just installed carpet pad over it. The tool cleaned the concrete very nicely, thereby leaving a fresh concrete surface for the thinset to adhere to.

Make sure you get supplemental dirt bags, rated for concrete and drywall dust, for your Shop Vac. The regular bags catch most, but not all the concrete dust. The regular bags also allow the Shop Vac pleated filter to plug up very quickly. The bags rated for concrete dust work beautifully.

4.0 out of 5 stars Dust free grinding, June 7, 2005

By 

tool collector (west lawn Pa) - See all my reviews

This review is from: Bosch 1773AK 5-Inch Concrete Surfacing Grinder (Tools & Home Improvement)

I used 1773AK concrete grinder to remove quikrete concrete resurfacer that never turned color and was streaky. It did excellent job of removing product that was applied 1/8" thick. Dust collection was outstanding provided you either cleaned or shaked filter of vacuum often. Product loses star because it tends to trip overload protection often even when not pushed hard;despite using a 12 gauge ext cord(50feet). Overload tripped more often w/ new wheel which grabs a bit at first. Overload trips less when wheel has some wear on it. So far I have ground 13 sections of sidewalk and went used 3 diamond cup wheels(2 dc510s, 1 Dc520). I like 510 wheel the best for my aplication. One wheel and 4 sections of sidewalk to go. UPDATE:Finished the job. Grinder did well except for annoying overloads.
