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.

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.Read more ›

I do have a few tips. Dewalt makes a grinding wheel that fits this machine, part number DW4774. It costs about half what the Bosch wheels costs and lasts more than twice as long. It is available at most Lowes (usually only one per store) for about $60. It is slightly smaller in diameter (4.5in vs. 5in) so it does not get as close to the edge of the shroud. You will also have to use a spacer on the grinder shaft towards the end of the DW4774's life (use one clamping nuts that come with the grinder).
The tool _must_ be on its own 20A branch circuit. Do not run your vacuum on the same branch circuit! I have had no trouble with breaker tripping, but the tool does peg my current meter at 18.5A.
I docked one star mostly due to price. There are a few other minor issues. There needs to be a way to secure the vacuum hose in place other than friction. You don't want the vacuum hose to come off, even for a second! A high-power, low-power switch to reduce current and prevent breaker tripping would be nice. I would love to see a wet/dry version of this tool. I would also like to see a larger version (may have to be 240VAC).
