Drill bits are quite handy for the purpose of making holes in any surface whether it is concrete, stone or stainless steel. Drill bits are small sized metals or stainless steel bits that are fitted in drilling machine to pierce through walls. Drill bits come in different shapes and sizes to suit different purposes. The design of the drill bit is quite slim and sleek and they are coated with special coating materials to give them an attractive design.
Drill bits are designed for different types of drilling, from heavy to normal and it is their size and tip point which differentiates the working of a drill bit. Drilling is quite a compelling job and requires a lot of precision and correctness and therefore you just can’t use anything for drilling purpose. Only drill bits which are proper in size and fit the drilling machine should be used for drilling purpose in your homes or any other place.
Length of drill bits –
A drill bit is one object which varies in length quite normally. Drill bits come in different shapes but these shapes do not vary much from each other. Drill bits which are shorter in length are more easy and reliable to use. A shorter drill bit is most widely used due to the fact that it gives more precision and control in drilling process. These bits are compact and unlike long drill bits do not get broken easily. A shorter drill bit provides a lot more productivity and it is quite economical and advisable to use short drill bits for drilling purpose.
A shorter drill bit due to its productivity takes less time to do the job and it can also be used in areas which are compact and do not give right space to move the drill around.
Drill bits coating
Coating plays a quite significant role in the performance of drill bits. A normal drill bit which is made of metal and does not follow coating is quite less impactful than those that follow coating. A coated drill bit is more effective and gives higher accuracy in drilling. Coated drill bits are lubricated and give flow in operations. Drill bits through coating can also be made sharper and stronger. All these aspects are quite effective to increase the performance of a drill bit.
Types of coating material
Titanium – one of the best metal titanium in drill bits is used to give the strength to the bit and also provides hardness and resistance from heat. The material is quite hard and is quite durable. One of the most versatile materials, titanium drill bit can be used to drill in different materials like steel, wood and plastic.
Black oxide coating – this type of coating using black oxide material is the most common and inexpensive coating. This coating is quite prevalent and is mostly used in high speed bits made up of steel. A black oxide coating is highly resistant to heat and provides greater lubrication in the drilling process. Black oxide is quite robust and can protect the drill bit from corrosion and water damage.
The coating and length of the drill bits are quite important factors which should be kept in mind before making a buying decision for suitable bits. It is the coating and length aspect which mainly highlights the performance of your drill bits.
