Bosch Introduces Next Generation Concrete Surfacing Grinder Worldwide Market Leader In Grinders Offers Most Comprehensive Dust Removal System

Today, Bosch Power Tools introduced the 1773AK 5-inch Concrete Surfacing Grinder with the most comprehensive dust removal system of any concrete surfacing grinder on the market. Bosch completes its new line of grinders with this application-specific tool designed exclusively for demanding concrete projects.

Serious users of this grinder will find the new dust removal system especially helpful for a number of reasons. Compliant with UL and OSHA standards, this grinder meets and exceeds all regulations and recommendations with respect to dust removal and offers a cleaner alternative to other concrete surfacing grinders. A specially designed head makes this unit's dust extraction the most comprehensive of any grinder on the market. And a built-in dust chute connects to a vacuum hose for better, more efficient debris removal. Dust particles from such diverse applications as protective paint, plaster and sandstone removal can be hazardous to both individuals and the environment. The benefit to the users and those in close proximity - the collection of these materials prevents them from being inhaled.

In addition to dust removal, users can appreciate the fact that this tool weighs just under six pounds, an ideal alternative to the popular, and heavier, 7-inch grinders on the market. Although the larger wheeled grinders cover more space, users fatigue more quickly and therefore work less efficiently with the weight and size of the 7-inch grinder. The lighter weight and ability to control dust removal allow users to perform more work in a shorter time bringing added benefits in comfort and ease of use.

In addition to the exclusive dust removal system, standard diamond cup wheels (part # DC510) and a patented brush-ring for dust-free work provide unmatched debris management as well as cleaner and safer dust extraction. Additionally, the wrap-around side handle, for easy handling and multiple hand positioning, optimizes any working angle.

The 1773AK is perfectly suited for the professional. In addition to refurbishing and de-burring exposed concrete, the concrete surfacing grinder is also ideal for removing irregularities, formwork seams, and protrusions. Epoxy coated field windings, double sealed ball bearings and two lip-sealing protective rings ensure motor endurance and protect against dust contamination providing longer tool life. The Constant Response(tm) Circuitry provides soft start and maintains constant speed under load with overload protection, while the Service-Minder(tm) Light indicates when preventative maintenance is required.

This concrete surfacing grinder is the epitome of portable power with its robust 10-amp motor boasting 11,000 RPM. The slim ergonomic barrel design and slide switch add versatility. Operators have a more comfortable hold while still able to access tight spaces such as when removing mortar from the corners of bathroom floors. Additionally, the automatic restart protection guards against automatic start-up after a power failure, ensuring that the tool is only intentionally powered on
each time.

Whether the job requires the user to smooth floor pavement, remove graffiti and weather worn paint, or clean concrete surfaces before protective paint finishes are applied, the 1773AK will get the job done right. General contractors and form finishers will find this tool particularly helpful for pre-fabrication and form smoothing, creating fine surfaces on granite, building materials, artificial stone and concrete.
