Diamond Blade 350mm Concrete and Asphalt
Diamond Blades & Diamond Grinding Disks
Diamond blades are used instead of silicon carbine blades, where the size of the project ranges from medium to large and where price is an important factor. Masonry, abrasive stock bricks, block, cement pavers, asphalt and extremely abrasive applications are perfect for using diamond blades.
We stock the following sizes in our standard range however special types depending on the specific use can be ordered: (Please read “how to decide on which diamond blade to purchase” below)
|115mm Diamond Blade||Cutting of tiles or small clay brick.|
|230mm Diamond Blade||For cutting of clay / cement brick, chasing plaster or cutting stone.|
|350mm Concrete Diamond Blade||Cutting of concrete.|
|350mm Asphalt Diamond Blade||Cutting of Asphalt.|
|180mm Grinding disks||Grinding of concrete floors.|
|250mm Grinding disks||Grinding of concrete floors.|
How to decide on which diamond blade to purchase.
The bond is a term used for the softness or hardness of the powder metal being used to form the segments. The powdered metals hold the diamonds in place. The bond controls the rate at which the diamond segments wear down allowing new diamonds to become exposed at the surface to continue grinding with a "sharp" edge. An important step in choosing a blade is to match the bond to the specific material to be cut. Additional factors to consider are the type and power of the equipment to be used and the availability of water. Harder materials need a softer bonded segment to allow for continuous diamond exposure. Softer materials like asphalt or freshly poured concrete can use a harder segment to resist the increased wear that softer, abrasive materials create. In addition, the diamonds' grit (size), toughness, and concentration should also match the nature of the material to be sawed. For example, when hard materials are cut, the diamonds should be smaller.
There are other factors that should be considered when choosing a diamond blade for a particular application. These include the type (manufacturing method) of the blade, the availability of water in the cutting process, the horsepower of the saw, and the acceptable level of noise created by the saw. For example, if the horsepower of a saw machine is large, the diamond concentration of the diamond blade should be higher, or the bond should be harder. Higher diamond concentration will decrease the impact on each single diamond in working, while a harder bond will hold the diamonds more firmly.
Cutting with or without water
Many blades are designed to operate either wet or dry. However, diamond tools and blades work better when wet, and dry cutting should be limited to situations in which water cannot or should not be used. Water will prevent the blade from overheating, greatly reduce the amount of harmful dust created by cutting, remove the slurry from the cut, and extend the life of the blade, since diamond is unable to withstand the forces involved at the elevated temperatures involved in dry cutting ceramic and abrasive materials, and will be subject to rapid tool wear and possible failure.
