A project worker has to consider numerous tasks. Drilling holes is one of the most crucial tasks and need significant attention. No matter what material you use, drilling holes have immense use. And, when it comes to drilling holes, Drill Bit Sets come into action. Drill Bit Set is an assortment of drilling tools of various sizes that help you drill the holes as per your needs. Drilling sets come in a wide range of materials and costs. It depends on the type of material that you wish to drill the hole into.

Factors To Consider While Choosing The Right Drill Bit

It’s significant to select the drill bit set that is compatible with your material and helps accomplish your task. And thus, it is essential to find the Best Drill Bit Set for the job. The underlying guide discusses all the necessary elements to look for the right Drill Bit Set.

Shapes and Sizes

Every drill bit has a unique size and is used for a different purpose. Every task requires other base material and thus needs various drill bits. For instance, the drill bit for wood is different from the drill bit for metal. Numerous factors affect the difference in drill bits. The most crucial variances of bits are their physical size and shape.

Length: It is the drill bit’s overall length, which is the straightforward description of the physical length. Drill bits are categorized as their size, which determines how deep they can trill the hole.

Diameter: Diameter is the width of the drill hole. It comes in different sizes ranging from 1/16th of an inch to 1 ½ of the inch. It is also sometimes represented in metric units and starts from the range of 3 millimeters. 

Shank: Shank is the receding part of the drill bit that fits into the drill chuck. The hand- brace or drill grips this part of the drill bit. It comes in a smooth and hex-shaped end depending on the torque needed. The size of the shank is less than that of the flute and lead.

Flute and Lead: The cutting part of the drill bit is similar to that of a screw. The processing part or inner part of this curved groove is called a flute. Lead is the outer portion that governs the diameter. It also helps the drill stay true to the path. 

Point: It is the end of the drill bit which does the entire business. The most crucial feature of the drill point is the drill point angle. The drill point angles used are 90° for cutting, 118° for general drilling, and 135° for slower insertion into the hard materials. 

Metal Composition

In addition to the size and shapes, drill bits come in various material options. It’s important to use the right bit material depending on the base material used. Usually, the drill bits are made of metals, but their composition varies depending on the base material used. For instance, the metal composition of the drill bit used for metal differs from that used for wood. The most commonly used metal compositions in drill bits are

High-Speed Steel: It is commonly termed as an HSS drill bit. It is generally used for drilling soft materials like wood and plastics. HSS bit is made of carbon steel with some additional composition of chromium and vanadium. It is one of the most commonly used drill bits. 

Cobalt: Cobalt can bear more heat and is more powerful than steel. And thus, it is used for drilling hard base substances like steel. It can also withstand the resistance generated during the drilling. The cobalt drilling bits are marked with HSS Co, which gives the same strength on the challenging surfaces. 

Carbide Tipped: Carbide has robust strength and can withstand enormous force. It’s also very expensive, and thus manufacturers often use HSS for flute, lead, and shank but add carbide to the tip. And therefore, termed as carbide tipped. These are ideal for concrete and tile drilling. 

Solid Carbide: The solid carbide drilling bit is completely made of highly durable carbide metal. It has robust strength and can withstand the hardest materials. These bits work best on non-ferrous metals, and they do an excellent job on abrasive surfaces like fiberglass.  

Coatings

Metal is usually prone to corrosion which reduces their life. And thus, it is important to coat the metal drill bits to aid extended support and extend their life. The coating is a special additive that helps improve the overall perforce of the drill bit and makes the worker’s job easier. The most commonly used coatings are listed as under

Black Oxide: The black oxide coating is useful in retaining the lubricants and helps increase the productivity of the drill bit. It helps prevent rust and thus helps extend the life of the drill bit. 

Titanium Nitrate: Titanium nitrate coating adds extra protection to the drill bit. It helps prevent the wear and tear of the drill bit and is mostly used in the drill used for hard metals. 

Titanium Aluminum Nitrate: Titanium Aluminum Nitrate coating offers protection from heat and abrasion of metal. It helps maintain the condition of the drill bit during high-speed usage. 

Silicone: Silicone multilayer coating is a special type of coating that works best on dense surfaces. It prevents the wear and tear of the drill bit while using it on hard surfaces. 

Bright Finish: Bright finish is not the coating but a shiny finish on the drill bits. It is generally used on the drill bits used on the wooden and soft metal surfaces. These drill bits are affordable and give a long-lasting experience to the drill bit.

Why Choosing A Right Drill Bit Is Important?

It is important to choose the right drilling bit as it can affect the overall productivity of the task. Not selecting the right drilling bit comes at a great cost and can lead to underlying damages.

1. The wrong drilling bit can damage the base material, which could be a great loss.

2. The damage to the base material can add more to the expenses and efforts.

3. Choosing improper bits can slow down your work or even bring it to a halt.

4. Improper drill bits can also increase the chances of physical injury.
