![]() ![]() If used in a machine where speed regulation is possible, a general recommendation is the larger diameter of the core drill being used, the slower the speed. ![]() This is because they are designed to be used in power tools where in the majority of cases there is no facility to regulate the speed (SDS Plus, SDS Max machines etc.). Our diamond core drills are designed to drill holes in very hard materials and they do this by removing a cylinder of the material. Dry core drill bits, on the other hand, are the ideal solution when additional water is not required for the job application. In most cases, a wet core drill bit is the best solution. Recommended speed for these cores is largely governed by the power tool itself. The dry core drill bits, when used without water, generate a greater degree of tension and pressure on the blade, which might cause the drilling speed to slow down. Thanks to the use of sturdy diamond crowns, the Matest core drilling machines allow you to drill different materials (such as concrete, rocks, bituminous surfaces, etc.) and obtain cylindrical samples that can be used to perform different types of tests (compression, evaluation of the elastic module, etc).When cleanliness of breakout is critical, turn off hammer action and use ‘rotary only’ mode for the last part of the drilling process. ![]()
