Concrete grinders - Hand held

I stock quality DTA and Eibenstock hand held concrete grinders for sale in Perth, Western Australia.

For tips on grinding, see information on cup wheels here, or grinding shoes here.
Some of these grinders have very big motors. Try to put your vacuum on a seperate circuit, or at least a seperate power point.
This will allow the bigger saws to draw their rated power, and perform as specified.

Silica dust - when workers cut, crush, drill, polish, saw or grind products that contain silica, particles are created, which are one-hundredth of the size of a grain of sand. These can get  stuck deep in the lungs. 
Ensure precautions to limit exposure to dust are in place.
See the WA government's info on silica dust here.

Grinding Concrete:

It is impossible to make a recommendation on YOUR grinding job. Every job is different.

Grinding hard concrete does not produce much dust, and it is usually soft and non abrasive.
The diamonds cut and break as normal, but the metal bond surrounding them is not worn away easily without the dust, so the diamonds are not exposed as much as with soft concrete. The diamond segment glazes over and stops working and rubs on the floor instead of cutting it. You can use larger diamonds (around #25 grit) to increase dust production. Also, reduce the surface area with fewer segments to increase the weight per square centimetre.

Grinding soft concrete usually produces sufficient gritty, abrasive dust that will wear away the bond and expose the diamonds adequately. In fact, too much dust can cause the grinding wheel to wear too fast, so vacuum up excess dust. Reduce the weight on the wheel or increase the surface area with more segments to reduce the weight per square centimetre.

Inspect your cup wheels regularly to make sure diamonds are exposed adequately  and that they are not overheating . Even the best shoes will perform badly if used in the wrong application.

Tips:
Dampening the concrete before grinding, or even spraying a little water may assist with your job ( be careful mixing water with electricity - use an RCD). It will make a grinding paste.
Similarly, clean builders sand on the surface, or reducing dust extraction, will help the grinding process.
A grinding compound such as Worx+ Totally Cut Sikk can assist grinding.
Use only heavy duty (2.5 mm2 minimum but preferably 4 mm2) extension cords and keep them as short as possible (under 15m).

Remember - every job is different. The enormous combinations of different types of surfaces, different shoe styles, with many different bonds and grits, plus different machines and varied operator experience means it is impossible to guess what will give the perfect result the first time. Some experimentation is often necessary to achieve the required results.
