Introduction:

Drill bit is nothing but the tip of the drilling machine, which is used for creating cylindrical holes. Thus, while the bit is essentially required to create the hole, the drill is the tool that holds it and provides it with axial force to make the desired hole.

Types of drill bits:

Drill bits are divided into many different types. This division is primarily based upon the surface that the bits are primarily used on, during drilling operations. In brief the drilling bits can be divided into two main categories, metal drills, which are most effectively used on metals and wooden drills, where the bits are most effectively used on wood. Other important drills that are commonly used on many different surfaces are the diamond core bit; hole saw bit etc. large drilling bits are also available for oil and gas drillings. In metal drill bits, the twist drill bit is the most common and most popular bit. Other bits that work on metal include gun drills, core drills, spade drill etc. wooden bits as the name suggests, work best and most effectively on wood and other similar material. The most popular wooden bits include the auger bit; gimlet bit, lip and spur dill etc. Drill bits can also be differentiated in terms of size. For example, the twist drill is very small as compared to other types of drills. The best way to determine which drill is best suited for your job; you require certain degree of expertise and skill. Since dill bits can very dangerous if not used properly, care and caution and skill are required for operating them effectively.

Material used in drill bits:

The material that is used to make drill bits depends a lot on the type of bit you plan to use. The most common material for making bits are however carbon steel, high speed steel and in the case of wooden bits, soft steel. Tungsten carbide is also used in certain special kinds of drill. For providing coating to the drills, titanium nitride is the most popular. However Zirconium Nitride can also be used in many other types of bits.

Despite their durability and strenghth drill bits need to be cared for and sharpened from time to time, to maintain your standard of work effectively for many long years.
