The 5 Best Drill Bits

You must already be aware that drill bits are available in a wide range of sizes and coatings. You can also find specific types that are appropriate only for particular surfaces. Generally, drills come either with a 1/2-inch chuck or a 3/8-inch chuck.

Most sets of drill bits boast of an array of bit sizes. If you have concerns about using smaller bits with a larger drill or vice versa, you can tackle them using an adapter. For example, for residential work, your machine is likely to be a 3 4 vs 1 2 drill that is apt for contractors.

You can handily use a 3/8 to 1/2 drill chuck adapter whenever your drilling bustle calls for a greater hole.

Below, you will find a collection of the best drill bits that can satisfy your requirements with versatility.

Selecting the Best Drill Bits: Buyer’s Guide

If you want to perform a fine job, you must equip your drill with only the best drill bits. When buying drill bits, there are numerous factors that you must take into consideration. In this manner, you can assure yourself of their quality and delivery for a seamless experience.

Here are some bases on which you must evaluate potential choices for best drill bits.

Construction Material

There is a wide range of materials that go into the construction of drill bits. You can find hard materials like carbides that do not turn blunt quickly. However, such materials are often susceptible to breakage.

The nature of your drilling requirements must dictate the material you select for your drill bits. The ideal choices include high-speed steel (HSS) and cobalt steel alloys. For example, you may choose to use a 1 2 inch vs 3 8 inch drill for professional purposes. A similar explanation applies to the drill bits you use.

High-Speed Steel

HSS bits are heat-resistant in an impeccable manner. You can drill through wood, metal, and plastic with HSS drill bits.

Cobalt Alloys

If your usage involves drilling through stainless steel, then cobalt drill bits are suitable for you. They can maintain their hardness even at high temperatures.


Drill bits usually come with coatings that increase the life and performance of the bits. Typically, you will find drill bits with black oxide or titanium plating. Black oxide is a more affordable variant than titanium, providing resistance to heat. Black oxide also functions as a lubricant.

A titanium coating contributes to the longevity of the tools and provides excellent cutting. Such a covering is suitable for heavy-duty drilling tasks.

Pieces in a set

Drill bits come in sets, so you must scout out what kind of a collection will suit your needs. You have a wide range of sets at your disposal, some with 13 pieces, others with as many as 100 items! If you have a typical 3/8 drill, you can use a 3/8 to 1/2 drill chuck adaptor to benefit from the larger variant. If you need the best drill bits for daily household tasks, then a smaller set would be appropriate. If you engage in more extensive projects, then a comprehensive drill bit set would be best.

To sum up

Even though the variety of drill bits available today is impressive, some undeniably boasts of an edge over others. With this guide’s help, you will be able to add more value to your decision when buying the best drill bits.

Frequently Asked Questions

Do you have any persisting questions regarding drills or drill bits? In this section, you will find all the answers that you seek.

1. 3 8 drill vs 1 2 drill: What is the difference besides the size of the chuck?

A 3 8 drill has a 3/8-inch chuck, and a 1 2 tool has a 1/2-inch chuck. In addition to this, you can gain insight into the case of 3 8 drill vs 1 2 drill if you judge the nature of your requirements. 1 2 cordless drills often feature excellent batteries and work well for almost all projects. 3 8 drills have incredible power, and people most commonly use this size.

The batteries drain slower in a 3 8 drill vs 1 2 drill. It is because larger bit sizes generate more torque. However, 3 8 shanks may snap more easily. Most hobbyists use a 3 8 drill vs 1 2 drill that is suitable for contractors for their projects since it can withstand heavier usage.

The lighter variant is the 3 8 drill vs 1 2 drill that can get tiresome to hold for a lengthy period in terms of weight.  

2. How can I use a 1/2-inch drill bit with a 3/8 drill?

If you own a drill with a 3/8-inch chuck, you can use a 3/8 to 1/2 drill chuck adapter to accommodate a 1/2-inch drill bit. When buying a 3/8 to 1/2 drill chuck adapter, you must take the shank of your drill into account.

Check whether your machine has a round or a hexagonal shank and pick a 3/8 to 1/2 drill chuck adapter accordingly. Some adapters may allow you to use them with multiple types of fittings. These attachments come either in a keyed form or a keyless variant. 

3. Which is the best drill bit for metal drilling?

If you want to perform a task that involves soft steels, then a high-speed steel drill bit will be a suitable option. For harder metals such as stainless steel, cobalt drill bits are the best available solution.

As for the coating, black oxide plating will make drilling into metals easier since it reduces friction. Titanium-coated drill bits are also excellent, as they are more resistant to wear and tear. These are apt for construction purposes just as a 1 2 inch vs 3 8 inch drill.

Keep in mind that you will find variations even within the category of drill bits with a titanium plating. Titanium carbonitride (TiCN), and titanium aluminum nitride (TiAlN) coatings are the two types you are most likely to come across.

4. How is a twist drill bit different from a pilot point drill bit?

Drill bits with a twist-pattern are fit for drilling into plastics, wood, and even metals. Such drill bits are suitable for home repairs and domestic maintenance projects, as they are fruitful even while drilling into masonry.

Pilot point drill bits are perfect for woodwork projects and drilling into metal surfaces. Drill bits with a pilot point have a pointed tip, which prevents ‘walking’ and results in a cleaner finish.
