Shark 460 Concrete Grinder

The Shark 460 Concrete Grinder is a variable speed, planetary drive, concrete grinder & polisher with no belts or pulleys. It has been specifically designed for concrete polishing, however, as it has a large 3kW, 4Hp motor it also performs exceptionally well as a general purpose concrete grinder.

Running off a general household 10 amp power point, it is ideally suited for domestic to smaller commercial projects up to 500m2 and has a grinding diameter of 460mm. It is compact and easy to store away with a convenient fold down handle.

The Shark 460 Concrete Grinder offers 3 diamond plate holders with an easy to use “Quick Change” diamond tooling system.

In order to maintain a dust free environment, the Shark™ 460 also features an enhanced dust control system which includes a Dust Shroud and a dust connector which can be used with Sharks array of Dust Extractors.

Testimonial – “I would like to congratulate you guys on your superb selection of concrete grinder and industrial vacuums. In August 2016 we purchased both a Shark S460 floor polisher and a Shark H24 dust extractor, both these products are outstanding and to date both these machines have performed flawlessly.” Martin Wynne
