Buy Diamond Concrete Grinding Disc from online store or directly from Chinese tool suppliers & distributors. Most of the concrete grinding tools manufacturers offer free shipping to save your time, money and efforts. This is a perfect tool for experienced concrete workers and it can quickly grind small diameter stones and its blade should be sharpened regularly. This concrete grinding disc can be easily replaced whenever it gets damaged or dull.
What is diamond concrete grinding discs?
Diamond concrete grinding discs are durable, strong, and have excellent grinding power. These discs are designed specifically for concrete surfaces, and it is used in various industries including building construction, paving, road construction, and highway maintenance, to name a few. It is a universal jointing product which is very convenient for all kinds of jointing applications. These diamond-shaped grinding discs are highly versatile because they can be mounted on any kind of construction machinery.
Follow specifications
Before using, make sure you check the following specifications of these concrete grinding discs: The diamond disc has an expiry date stamped on its side. Usually, the expiry date is stamped on the reverse side of the disc. Make sure to read and understand this date so you know exactly when to change or replace the disc.
Most of these discs are made with boron nitride, which makes the grinding process easy and faster. It also provides a layer of lubrication that helps eliminate friction and makes the grinding action smooth. These discs are also resistant to heat and chemically treated with coatings. The protective oxide layer helps prevent concrete grinding discs from scratching and eliminates the chances of abrasive crudges on the surface.
Diamond-shaped concrete grinding discs can only be ordered from authorized distributors. This is to ensure that the product complies with standards and regulations set by the Society for Construction Safety, which requires diamond-shape grinding disc. Some distributors may even provide free-drilling service, but it is not guaranteed.
As for the other two common types of concrete grinding discs, steel cutting disc and alternate top round bar disc, most manufacturers indicate the expiry dates on their product packaging. The alternate top round bar disc is usually stronger than its steel counterpart and more durable and able to withstand constant usage over a period of time. Abrasive-resistant coatings may also be provided. Discs that come with protective oxide layer are usually more durable and can last for many years before needing to be replaced.
Higher speed and greater force
However, diamond-shaped concrete grinding discs offer higher speed and greater force when grinding, making them better choices if you need smooth results without frequent grinding. However, diamond products do not hold up well to extreme temperature changes and may crack easily. They also produce less-dense outputs and tend to produce scratchy sound. If you want something durable that will last for years, steel expiry dates should be considered.
The final type of cutting disc that should be considered is the nylon cutting discs, which have larger areas of teeth and a higher tolerance level to heat. Nylon discs are more flexible, but more prone to snagging and bending. Expiry date is not indicated for this type of concrete grinding disc. This is because no universal temperature and humidity conditions are set for the nylon discs. Expirations may vary depending on the humidity, temperature and season.
Several sizes and types of concrete grinders
Concrete grinders are available in several sizes and types. Grinding discs are designed to control the depth of the grinded concrete floor. Some discs have larger areas of teeth that can take-up a wider area of the concrete floor while others have smaller teeth to produce a finer finish. Because these discs are designed for different surface preparation needs, you have to check the specifications of the machine along with the concrete floor that you plan to work with to make sure that the grinder will fit your project requirements.
Aggressive flooring machines are preferred by many concrete contractors because of the quick speed of the grinding discs as well as the ability to create a variety of designs and pattern using two or more discs. Although it produces a finer result, diamond abrasives are not recommended for concrete floor finishing. Diamond grinding discs are best used for exterior surfaces that are exposed to the weather, such as patios and walkways. The large surface of the diamond discs can chip off or damage sensitive engineered concrete. The diamond disc is also not recommended for areas where it is important to have a level finish to prevent flooding. On the other hand, diamond grinding discs are commonly used in concrete grinding equipment for grinding down limestone and dolomite stone.
Aggressive concrete grinders are designed to achieve rapid and consistent production of concrete. However, these discs require a good amount of manual labor, which makes them unsuitable to use for projects that require a higher degree of detail. Concrete grinding discs, used together with diamond discs are ideal for projects requiring detailed finishing of concrete and other materials.
