As a construction professional or concrete worker, having the proper concrete grinder will make or break your job. Before discussing which floor grinder is the right one for you, we need to discuss what grinders are and the differences between them.
Concrete grindersare horizontally rotating disks that are able to profile, level, clean, and polish concrete. These machines can perform a variety of tasks including, removal of existing epoxyor paint floor coating, light surface texturing and surface preparation.
Types of Grinders
When shopping for a concrete grinder, it is important to understand which type of grinder is right for your application. There are three main types of concrete grinders:
Walk Behind Concrete Grinders
For large-scale, typically industrial scenarios, a walk-behind grinder is the definitive choice. Walk-behind grinders range in size from single-disc to dual, triple, or four-disc machines. A single-disc floor grinder will cover roughly 10-12 inches in a single pass; yet a four-disc grinder will cover 32-34 inches in a single pass. This diversity in pass width allows for a walk-behind grinder to be adapted to fit any scenario.
On units with more than one grinding disc, the discs counter-rotate to provide unmatched balance so the machine will not pull from side to side; resulting in a smoother and more uniform finish. For an even better finish, and easier application, some walk-behinds are equipped with floating heads that will follow the contours of the floor to prevent uneven grinding.
A benefit of a walk-behind grinding solution is the ability to stand versus constant kneeling. Walk-behind operators are able to stay standing and out of the way of harmful silica dust. Handheld operators are forced to work on their hands and knees, putting them into an unnatural position for an extended period of time; as well as potentially being exposed to greater levels of harmful resurfacing dust. This is an important feature that must be taken into consideration when deciding for or against any concrete grinding solution.

Handheld Concrete Grinders
Compared to walk-behind grinders, handheld machines are a strong alternative whenever the job does not require as extensive grinding work. These machines are perfect for small sized projects and spaces, making them the perfect addition to a walk-behind grinder. Handheld grinders are the perfect solution for hard to reach spaces like corners. This landmark feature gives a quality handheld grinder a place in any concrete professionals tool kit.
One negative surrounding handheld grinding solutions is the lack of consistent weight. When compared to walk-behind grinding solutions, handheld grinders can be susceptible to fluctuations in operator pressure which lead to variations in grinding consistency. Additionally, handheld grinding solutions are less compatible with most common dust prevention systems. Walk-behind systems are able to connect with common dust prevention systems to eliminate unhealthy airborne particles originated by the grinding process.
