The best drill bits are crucial for any kind of project – be it for DIYs that require only a simple corded drill or professional contractors who rely on cordless units. These come in varied shapes and sizes and are made of different materials and drill bit coatings depending on the project. Some examples include Titanium, Cobalt, Diamond, and High-Speed Steel.

With a welter of options available in the market, it is vital to know who makes the best drill bits to narrow down your choice. In this article, we answer precisely that question and guide you regarding their use.

What Are Drill Bits Made Of?

Not all products are made equal and can work on all applications. There are different types of drill bits, and knowing the makeup is an essential factor when knowing what their applications can be.

Titanium is one of the lighter metals that is used for such products and yet is quite strong. It is corrosion-resistant and has high heat – and fatigue – limit. It is one of the more attractive options and is used for long and repetitive runs. If you’re wondering – “What are titanium drill bits used for?” then have no worry since it can cut a variety of surfaces such as wood, plastic, and even steel and iron, which makes it a highly versatile coating.

The product also comes in a case that keeps the bits organized.

Cobalt Drill Bit: CO-Z Cobalt Multiple Hole Step Drill Bit (5 pcs.)

Cobalt Drill Bit

These are chiefly used for materials such as stainless steel, which high-speed steel (HSS) units cannot cut. These are less susceptible to high temperatures, more so than even HSS. The only drawback with these is that they can be quite brittle.

If you’re looking for a cobalt unit, then we would highly recommend the aforementioned CO-Z product. Since they have titanium coatings as well, they are incredibly durable and do not share the brittleness that other cobalt units are associated with. The set contains five different sized shanks that provide a smooth boring experience. The X-type openings of the units are designed to improve accuracy while limiting cutting waste when handling the item. Most professionals recommend this product for smoother and rounder holes that can be attained with minimal shocks.

High-Speed Steel Drill Bit Set: Drill America Heavy Duty High-Speed Steel Drill Bit Set (29 pcs.)

High-Speed Steel Drill Bit Set

High-Speed Steel is a type of carbon steel that is designed to withstand high temperatures without sacrificing structural integrity. This allows them to endure the friction that is associated with high-speed turning that raises temperatures significantly. These also tend to have a long life when coated with titanium nitride, which decreases friction and provides better lubricity.

For those who’re wondering who makes the best drill for metal surfaces, we would highly recommend this one. The product in question is a premium high-speed steel set that is quite hard and resistant to wear. Its black and gold oxide finish is corrosion-resistant, which significantly increases the longevity of the bits. Both professionals and amateurs alike can easily use this unit as it is designed for self-centering, which reduces thrust and walking.

MultiConstruction Drill Bit: Bosch MultiConstruction Drill Bit Set (5pcs.)

MultiConstruction Drill Bit

MultiConstruction units are intended for tackling different types of surfaces. As the name suggests, they incorporate various materials in their design that give them an edge over other materials. They generally have a high-quality diamond tungsten carbide head which is highly durable and has long lives.

When readers generally ask – “Who makes the best drill bits for steel surfaces,” we guide them towards Bosch. They are industry giants that make the best drill bit for metal and other surfaces such as wood and plastic. Here too, we have a product that has never disappointed its users. It is designed especially for fast work in hard materials made possible thanks to its sharp ground cutting edges and can be used in hammer drill and drivers as well.

Where Can I Use Drill Bits?

They can be used on a variety of surfaces. However, it is essential to know what kind of surfaces your unit can handle. In this section, we shall take a look at what surfaces the different types of units can be used for.

Metal Drill Bit

The best drill bits that work on metal surfaces are high-speed steel, titanium, and cobalt bits. Most people tend to get confused when considering cobalt vs titanium drill bits. Though titanium coated units are quite durable, they tend to wear away, especially if you sharpen them with a sharpener.

Cobalt units, on the other hand, are manufactured from solid alloys which make them resistant to high temperatures. Those wondering what kind of drill bit for aluminum surfaces is ideal would do well to choose a cobalt drill tip. They do not lose their edge over time though they are brittle and a little more expensive than titanium. They are generally recommended for tackling mild steel or other metals.

Masonry Drill Bit

For tackling brick, solid concrete, and another masonry, a sharp unit is recommended. So, what are the strongest drill bits? A diamond hole saw, or tungsten carbide bits are ideal. They are used in impact, hammer, or percussion drills, which pulverize the surfaces when they come into contact with the tip.

Wood Drill Bits

Various wood drill bit types can effortlessly bore in different kinds of woods. Spade or flat wood bits are recommended for drilling through wood rapidly though they do produce a splintering effect if too much pressure is applied.

Another option is to use a lip and spur bit for drilling timber. Similarly, hole saws can be used for tacklings large holes into wood. They have small serrated teeth and a “blade” in the form of a cylinder, which is designed especially for drilling wood, making them the best drill bits for timber.

Drill Bits For Plastic

The best drill bits that are used for wood can be used for plastic as well. However, it is advised that you drill slowly with them. Fast drilling can produce enough friction to melt the plastic, thereby clogging the tips. Though this problem doesn’t occur when tackling thin plastic, it can be quite pronounced when boring through thicker sheets and acrylic.

Drill Bits For Glass and Tile

Most beginners wonder – “What kind of drill bit for glass is ideal?” The answer is the most reliable kind, which happens to be diamond core bits. These are also the best boring through the tile. However, since the coating tends to wear away over time, they have a limited lifespan. Another option is to use spearhead bits, which are made from tungsten carbide. It is advisable to drill at low to medium speeds with a soft cloth underneath the surface.

How To Use Drill Bits

Before you can start with the best drill bits, it is essential to know how to go about using the units. For starters, it is essential to know how to put a drill bit in a drill. There are two kinds– one that uses a key, and one that doesn’t.

For a keyless unit, first of all, loosen the chuck, which is the cylinder-shaped end of the drill that holds the bit. Turn it clockwise to open the clamps and loosen the chuck. Put in the bit with the shank facing the clamp of the drill chuck and insert it into the chuck. Squeeze the trigger to tighten the chuck, and you’re all done.

If you want to know how to change a drill bit for a keyed drill, firstly insert the key into one of the holes on the side of the chuck and turn it counterclockwise. This will slide out of the unit. Insert your unit so that the shank goes in first. Tighten the key clockwise and remove it, and it will be secured.

It is also essential to know what size drill bit to use. The best drill bits come with a hole chart that will help you identify which bit size is right for the job. For softwood, a bit that is 1/64” smaller than the hole is ideal. For other materials, use a bit that is exactly the same size as the hole.

We hope that through this article, you now have a thorough understanding of different products and their usages. The units should be selected depending on the job and the material to be bored. For similar articles on a variety of tools and DIY projects, stick to HandyHomeMaster.
