Easy-to-use, finishing tool
By Jerry Robison
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.

By Maureen
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.

By Charles B. Naumann
This reallly is a great tool. It grinds down concrete with little to no mess. This tool works very well for cleaning paint, thinset, drywall mud and splattered concrete off of slabs. It is also great for smoothing joints or cracks and for making minor slope adjustments in concrete to eliminate standing water. I am amazed at the number of uses I am finding for this tool!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).
