Abrasive sawing with the incorporation of diamonds in the saw blades as well as drill bits since it is the hardest substance out there and can cut into concrete, granite, and other such tough materials with precision and care. But there are a lot of different kinds of diamond blades that are designed to perform on a specific material or at different speeds. Therefore it is essential that one considers the factors listed below before choosing a diamond blade for concrete cutting or consult professionals to guide the diamond concrete cutting process accurately.
In order to select an appropriate diamond blade, you must be aware of the mechanism, principles, and characteristics of the tool. The components of the blades include a metal core, synthetic diamond crystals, the matrix, and the weld, each of which is necessary for important functions. These components vary in different makes of the diamond blade. The diamonds that are exposed on the surface do the cutting at different speeds and the matrix sheds away once the diamonds become dull through use. This releases the worn diamonds to give way to new sharp diamonds. Therefore the hardness of the matrix is in control with respect to how quickly the blade wears.
The material hat is to be cut and its metallurgic bond plays a very important role in deciding the correct blade to be used. There are several blades that are designed to be versatile and cit different materials but these are often limited by the diamond quality and hardness of the bond. The ingredients of the materials like concrete, asphalt, or green concrete may be of help to decide the best suitable blade in order to have clean and smooth cuts. The aggregates can be tested through a Moh’s test. The diamond bade manufacturers classify the blades based on the ability to cut hard, medium, or soft aggregates which can be analyzed to select the blade by the user.
Another essential aspect to consider while deciding which blade to opt for while diamond concrete cutting is the equipment that it will be mounted on. The blades should match the speed range of the saw as operating it at a slower speed than recommended can result in a shabby performance whereas if it exceeds the recommended speed can risk damage to the blade. Also, the diamond blades that are manufactured for wet cutting should be used with a piece of equipment that can impart water in a continuous manner. While cutting green concrete choose a blade and equipment that can reduce the spalling to a good extent and do not consider a blade that has a diameter that is greater than the recommended diameter and cutting depth capability of the saw.
This is usually pre-determined by the job but can also depend on one’s personal preference. Opting for dry cutting is a good way to get rid of the mess created y the wet slurry or keep water pipes and tanks handy while working. Whereas the wet cutting ensures minimal dust reducing the chance of inhalation by the operators. The major difference in the blades is of welds that enable the blades to sustain the heat generated throughout the process. Dry-cutting blades are also suitable for decorative cutting o the concrete. The wet cutting procedure is useful for joint cutting in cured concrete slabs as it accommodates deeper cuts.
Smaller diamond drilling jobs are warrantied to be completed efficiently with a cost-effective blade but some premium blades that last for longer can cost a relatively higher than these. The designers keep these factors in mind as diamonds are bound to come at a cost and devise cheaper blades for beginners or one’s carrying out small projects at home. This decision can be made by deciding whether the initial cost or the overall sawing cost is more important. While purchasing a blade for diamond concrete check for the CSDA code while helps in figuring out the configuration of the blade in a swift and easy manner.
