Howdy DIYer,
This unit does not come with a diamond wheel. They are readily available at your local Home Depot. Here is a link to some diamond blades:

I need to remove mastic from a concrete floor and smoothen it. I have about 800 sqft to do. Can I get away with this kit, which is half the price of the CSG15 Bosch concrete grinder?

Thank you for your question. The 18SG-5K will work for your application. This model provides standard grinder use plus grinding of concrete with the use of the surfacing kit. The CSG15 is designed specifically for grinding concrete providing longer operational life, including sealed motor and sealed switch, double sealed ball bearings and two lip sealing rings to protect against dust contamination. If you are planning to grind concrete only we would recommend the CSG15. If you do not plan on using the grinder for concrete only and will use for other applications as well then the 18SG-5K would be a better choice. Read Less

can I grind / level concrete floor with it

This question is from Surface Grinder Kit with 1821 - 5 in. Grinder, Shroud, Cup Wheel

August 18, 2014
I have a small 4 x 10 ft hall way. After taking out the vinyl flooring we fond the concrete floor with little bumps all over and very rough. We either want to resurface the concrete to stain it (but the bumps would stick out) or put a floating hardwood floor over it. Would this grinder work to do this job?
Thanks

Rated 5.0 out of 5.0 by Grinder Grinding Awesome! I used to grind floors in the Palm Springs area for residents, so I have had previous experience. This little guy does a great job! The deal for all the components is unmatched! Highly recommend this equipment. Thank you very much. August 3, 2016
Rated 1.0 out of 5.0 by Dust shroud did not fit Manufacturing flaw perhaps but the shroud did not fit as intended. May 17, 2014
Rated 5.0 out of 5.0 by Works as advertised The vacuum attachment is a definite must if using in an area that one is still living in. Grinds through the concrete really well. December 10, 2013
