Bosch 1773AK 5-Inch Concrete Surfacing Grinder Review

Average Reviews:

(More customer reviews)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.

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 SafetyBosch 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 OperationThe 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 LifeWith 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 UseA 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.
