Drilling is the operation of cutting a hole in a material using a drilling tool. The drilling tool usually consists of a long cylinder with a drilling bit fitted into it. The drilling bit performs the actual cutting operation.
It has cutting edges and helical grooves to take out the chips. There are different kinds of drilling bits such as Spade Bit, Twist Bit, Hole Saw, Fostner Bit, Masonry, etc.
A Hole saw is generally preferred over twist drills or spade drills because it can accommodate holes of bigger sizes with less power and faster. The hole saw doesn’t cut the core of the material but the outer edges only. However, it is mostly guided by a pilot drill bit which saves it from walking and stabilizes it reducing the vibrations to minimum. The saw consists of a metal cylinder mounted on an arbor with cutting edge having saw teeth made of industrial diamonds. The arbor may carry a drill bit for boring at the initial stages of drilling. There are two types of Diamond Hole Saws: Adjustable and Circle Cutter. The adjustable hole saw consists of a number of thin metal saw blade rings which can be fitted on one side into any of the large number of grooves on a flat disc and into the shank on the other side. So a hole saw of many different sizes can be obtained. The Circle Cutter, which is also a kind of adjustable hole saw, has one, two or three adjustable teeth that can be moved on a platform having a pilot bit. So many different variations in sizes can be obtained in this way.
Diamond core drill bits can be used in both dry and wet drilling processes. However, the type of material to be drilled decides the process to be followed. For example, if you’re drilling a very hard material such as reinforced concrete or granite or marble, then you need to use water along with the drilling process to drain away the excess heat generated during the process. Otherwise, the drill bit may get damaged, and lifespan may decrease and would not be able to perform efficiently leading to a poor finishing over drilled products. The diamond hole saw bit can be used for almost all kinds of materials using granite, marble, glass, etc. In fact, they’re very widely used in industry for producing holes in granite slabs and structures. It saves a lot of time and money. However, there are some precautions that need to be taken as well. For example, if you’re using a portable saw, then it must produce considerable torque at low speeds. Also, the kick-back from a powerful saw can be dangerous and therefore long side-handles should be put in use.
So if you’re interested in buying these diamond hole saw bits, there are sets available online with different diameter sizes of bits such as 3/4”, 1”, 1 ¼”, 1 ½”, 2”, 3”, 4” and multiple sizes in between.
