Masonry drills are used to drill holes in hard materials, requiring a high-quality drill bit and proper technique. Electric drills rotate a drill bit with sharp edges, and masonry drills have a hammer action for better results. Tungsten carbide drill bits are recommended for masonry drilling.
A masonry drill is used to drill holes in concrete and other hard, brittle materials. Drilling holes in masonry requires the proper drilling tool, a high quality drill bit and some technique on the part of the operator. A masonry drill is often used in building construction and some home improvement projects, such as finishing a basement.
A drill is a power tool specially designed for drilling holes. It is usually electrically powered, but can also be operated using air pressure. The power drill rotates a cutting tool called a drill bit. A drill bit is a cylindrical shaft that contains helical flutes, known as flutes, with sharp cutting edges for cutting and removing drill material.
Concrete and other hard materials require a good quality electric drill with different working characteristics. These include the ability to vary the rotational speed, set the depth of the hole to be drilled, and handles or devices to precisely position the drill to achieve the desired position and orientation of the hole.
Perhaps the most useful feature required of a masonry drill is the hammer action. Hammer drills, or rotary hammer drills, provide a hammering action along the axis of the drill bit as it rotates. The function of a hammer drill is similar to a jackhammer, which is used for the removal of concrete and masonry materials in large construction projects. A hammer drill increases the drill bit’s ability to remove material quickly and with less effort, producing better-quality holes with greater accuracy.
A special type of drill bit is required for drilling in concrete and masonry. Masonry drill bits come in a variety of standard diameters and lengths and have different cutting surfaces depending on the application. More expensive bits are made using higher quality materials to improve cutting performance and extend bit life. Masonry drill bits vary in cost based on the material and characteristics of the bit.
The type of bit chosen depends on the material to be drilled and the size and shape of the hole required. Those with tungsten carbide tips are particularly useful for drilling into masonry when using a hammer drill. Tungsten carbide is a very hard and durable material that is wear resistant under tough drilling conditions, so the drill bit stays sharp for a longer period of time. The shaft, or shank, of the drill bit is also heat treated and surface hardened to maintain its sharpness and extend its useful life.
