What are the drill bits?
Drill bits or drilling bits are popular tools of cutting that are utilized to eliminate the material to create holes. These holes are commonly created in a circular cross-section motion. Drill bits can be found in hardware stores. They come in different shapes and sizes and are used 5o create several types of holes on many kinds of materials like glass, wood, ceramic, plastic, metal and so much more.
Drill bits are attached to the drilling machines for drilling. The machine powers the drill bits to cut through the material by a rotating motion at a high-pressure point. The drill grasps the top end at the bit. There are also special drill bits that are designed to create holes without a circular cross-section.
Features of drill bits
There are several types and features of drill bits. Here you can check this comparsion of drill bits for glass and other hard and soft materials. Some of them are as follows-
The spiral that is featured in the drill bit helps in controlling the rate of chip elimination. A quick spiral drilling bit serves the purpose of monitoring and operating in the high feed rate operations and applications specifically under low speeds. In this process, the removal of a huge volume of chips is needed. Low spiral drilling bits serve the purpose of cutting applications in place where high cutting speeds get traditionally used.
The point angle is also known as the angle that is formed on the top of the drill bit. This feature determines the material that will be operated by the bit. If the materials are harder, the point angle will be larger and soft materials need a sharp angle. The point angle that determines the hardness and firmness of material influences the chatter, hole size and shape, and the wear rate.
The lip angle states the kind of support is provided to cutting edge. A bigger lip angle causes the drill bit to cut aggressively with the same point of pressure. This can result in binding and catastrophic failure.
The functional length of the drill bit helps in determining how deep you can drill the hole. Also, it determines the firmness and stiffness of the drill bit and the accuracy of the hole.

You can find drill bits and drilling machines on the local hardware store.
