A drill bit is basically a cutting tool or device which can be attached to a power drill. These bits are used to cut cylindrical holes in different materials. As it is available in different sizes, it can cut holes of different sizes too. These products are mainly used in machining and construction industries. Carbide and high speed steel are among the mostly wide and commonly used tools which can potentially cut into any type of material easily.
Spade Bit: This device has a flat blade surface and a pointed tip at the center. It is widely used on make holes in wooden surfaces. It can bore holes of different diameters.
Hole Saw : Another device is the hole-saw bit which has small sharp teeth. It can be used to make large sized holes into wood, plastic and light metals.
Twist Bit: This is another tool which can be used for a wide variety of purposes. It can easily bore holes into wood, plastic and any other thin metal.
Forstner Bit: It can be used to make holes for cabinetry and other furniture products. It makes round and flat bottomed holes.
Masonry: It is mainly used to bore holes into concrete and other stone surfaces. The tip of this tool is made of tungsten carbide. It is quite strong and durable compared to the other products.
Fields of Application:
Construction: It is widely used in the field of construction. Drill bits are used to bore holes into materials such as wood, metal, plastic and so forth. Workers often use different types of tools for different types of materials.
Glass and Tiles: Ceramic, glass and porcelain materials can be cut only with the use of diamond tipped bits. This prevails cracking and chipping of glass and porcelain while it is cut for different purposes. As the tip is made of diamond, it offers greater grip, precision and resilience.
Milling Machine: It is widely used in milling machines to bore holes into different types of metals. Carbide bits are used on hardened iron and steel as it can easily make holes in such materials. These products are available in different sizes and prices on many of the reputed online stores.
Lathe Field: These bits are quite essential while working on lathes. When the material is cut on the lathe, these bits are used to make holes in the center.
Different types of materials are used to manufacture these bits. Carbon steel is one of the most common and cheapest materials used but it can easily lose its sharpness. It also tends to overheat during the drilling process.
High speed steel is another material which is often used as it has the power to withstand heat. Cobalt steel alloy is also used to make holes into hard materials such as stainless steel. However, it tends to be brittle compared to the other products.
A huge variety of these construction tools and devices are made available on most of the reputed online stores at affordable price rates.
