 Bye, Bye, Thinset, March 15, 2006
Reviewer: J. Rullman

We wanted to replace about 1500 sq feet of floor tile set on concrete with about 3/8" of thinset. The tile was easy to remove using Bosch's SDS Plus hammer drill, but the thinset did not want to come up. So I took a gamble a bought the Bosch concrete surfacing grinder. Its great! It's so easy to use my wife did about 95% of the grinding. And if you hook the grinder to a good shop vac there is hardly any dust.

 Dust free grinding, June 7, 2005
Reviewer: tool collector
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. 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.

 Easy-to-use, finishing tool, July 24, 2004
Reviewer: 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.

     I worked in construction for 38  years installing Linoleum Floors, Formica Counter Tops, Ceramic Tile and lots and lots of Carpenter Work.  Now that I have put in my time at the trades I am selling tools because I believe after all the years using them, I am qualified to guide you in finding the right tool for the job.  -  Just for fun here's a picture of a couple of my trucks from my Floor Covering business, also a picture of my garage and my little dog called Marbles.  -  I will post notes here and there throughout the web site on tools and things that I think are important and/or solve problems, based on my experience.  -  When I was young it seemed impossible to finish a job successfully because there would be a part that just couldn't be done.  Later I discovered that when you have all the tools for the job the most difficult project goes smoothly.  -  Also lets face it, having a good set of tools is one of life's greatest pleasures.  Not only that but it is a great boost to your ego when you receive complements a job you have done.
