Buying Guide for Impact Driver Bit Sets

With the right impact driver bit set, any task involving screws and nuts is rendered easy and effortless. However, choosing just one set can be difficult, given the range of available options. So here's what you need to keep in mind.

Construction Material

The material that the bits in your bit set are made of will impact upon their performance greatly; furthermore, it will determine what material you can work with using your impact driver. Let's look at a few common materials used for constructing drill bits.

Carbon Steel

Out of all the available materials, this one is probably the cheapest. They're ideal for drilling through wood. However, they're unlikely to stay sharp for very long and might require frequent re-sharpening.

High Carbon Steel

Ideal for use with metal and wood, high carbon steel bits offer higher durability thanks to the tempering and hardening that they are subjected to.

Tungsten Carbide

This is the toughest of all available bit materials, which also means it is the most durable. Yes, this does make them more expensive; however, they are still quite brittle, so they're commonly used only for the tips of driver bits.

HSS (high-speed steel)

This is one of the most durable, sharp, and heat-resistant materials out there. If you're drilling hardwood, metal, or other hard materials, this is the right one.

Cobalt Steel Alloy

This is basically HSS but with a higher cobalt content. They are also highly heat-resistant, making them ideal for drilling through hard materials like stainless steel. However, cobalt steel alloy bits are somewhat more brittle than HSS.

Alloy Tool Steel

This is undoubtedly one of the most popular choices for the construction of bits, as it is very resistant to wear and offers great toughness and impact strength. Furthermore, bits made from tool steel are less likely to overheat from friction.

It’s good to remember that the best bits are those that have been heat-treated during production. This ensures greater durability and sharpness.


Let's say you're making holes in the wall to hang up some picture frames or have set about fixing up defected furniture. In such cases, you can do with smaller bit sizes. On the other hand, if you're using your impact driver for professional applications, you’ll need a larger set with a greater number of available sizes.

Some of the sets you'll find will have only a few bit pieces, while others may encompass 100 pieces. To figure out which one you need, first assess the job at hand. No one knows how big your project will be except you!

Flute Design

Some impact driver bits come in a “flute design,” which is characterized by twisting groove-like indentations along the length of the bit. The purpose of the flute design is to leave space for waste material to escape.

The 2 main flute design types are parabolic and 30-degree angle. The former is ideal for drilling through softer material, while the latter will allow you to drive through firmer materials such as steel.

FAQs for Impact Driver Bit Sets

Q: What is the best construction material for impact driver bits?

Ans: High-speed steel is our favorite, thanks to its durability and consistent sharpness. If they're too expensive for you, though, you can always opt for the reliable high carbon steel.

Q: What kind of impact driver bits is best for drilling through the wood?

Ans: Bits made from high-speed steel and carbon steel are most likely to serve you satisfactorily if you're working with wood (be it softwood or hardwood).

Q: Is it important to buy impact driver bits that have a coating?

Ans: Yes, if durability is important to you. A titanium nitride coating makes the bits much more resistant to wear. There’s also black oxide, which enhances resistance to heat, and is a cheaper coating material.

Q: How can I re-sharpen my drill bits if they go blunt?

Ans: You can make use of a bench grinder, diamond file, or belt sander for this purpose; some even like to do it by hand. Several tutorials are available online.

Q: Does the length of the impact driver bit affect its performance?

Ans: Yes, it does; longer drill bits will lower precision. Especially when working with steel surfaces, shorter drill bits are preferred, as their precision and speed are required.


With so many options out there, settling on just one best impact driver bit set is decidedly difficult. However, now that you've been exposed to all of the different options available on the market, hopefully, you'll be better able to make a decision.
