Reviews of the Top Impact Driver Bit Sets

1. DEWALT DWA2T40IR FlexTorq

Unlike typical impact driver bit sets, the DEWALT DWA2T40IR FlexTorq includes 40 pieces of high-quality bits that suit high-speed torque. Now, if you’re like me, you’ve probably dealt with wobbly bits and that’s no fun. What I like about this set is the magnetic bit holders. I used them, and let me tell you, those bits stay put—no excessive wobbling or anything like that.

You’ll find various driver and drill bits on this kit, like Phillips, hex shank, square, and other major bit types. Bits from this brand also went through CNC machining, so tip damages are less likely to happen. 

But what really sealed the deal for me is how easy this set is to organize. Even the longer bits fit snugly into place, thanks to these silver sleeves with magnetic features.

2. BOSCH MS4091 Driving Mixed Set

If you’re not on a tight budget, you should get massive impact driver sets like BOSCH MS4091. I mean, it’s got 91 drill and driver bits, and if you’re someone who frequently switches to different power tools, this variety is going to be a lifesaver.

Taking a closer look, some of the bits have a titanium [1] coating. Now, if you’re not familiar, titanium is heavy-duty stuff— it’s durable enough to withstand harsh conditions and strong impact. 

Like other impact driver bit sets, it’s designed with bit holders. It also offers great gripping power and long life, making the bits suitable for wood, metal, masonry, and many more.

3. DEWALT DW2153 Impact Driver Bits

Although it’s a more affordable DEWALT screwdriver bit set, the DW2153 proves its place on this list with its wide range of single and double-ended bits. What I like about it is that it’s not just for DEWALT tools—you can use its nut drivers and other bits with Makita 18V impact drivers, which adds a layer of versatility.

The Dewalt DW2153 is a decent kit for beginners because it’s made of shock-resistant steel that can withstand 2000 inches/lbs of torque. 

This DEWALT bit set also includes components that went through black oxide manufacturing. Because of this, all driver bits have extra strength to resist potential wearing during usage.

4. Milwaukee Shockwave 48-32-4062 Impact Driver Bit Set

When it comes to the best impact driver bit sets, price isn’t always an indicator of quality. Case in point: the Milwaukee Shockwave 48-32-4062. These go through heat-treated manufacturing to ensure durability. I’ve used these on several projects, and they’ve held up pretty well.

I also liked that the driver bits include a magnetic extension holder that allows you to reach hard-to-access areas. These bits are also engineered for high-torque impact drivers, so you can be sure they won’t crack under pressure.

Now, let’s talk about the case. It’s a bit on the quirky side, shape-wise, but I’ve come to realize that the design is intentional for shock absorption. So even if it looks a bit odd in the toolbox, it serves a purpose.

5. CRAFTSMAN CMAF1333 Drill/Driver Set

As an impact driver bit set optimized with a torsion zone, you can expect CRAFTSMAN CMAF1333 to deliver long life and powerful performance. I’ve used this set for various jobs around the shop, and let me tell you, the socket adapters are a breeze for tightening and loosening the bits.

Each drill bit included in this kit has S2 modified steel construction, making them durable enough to drive through different materials. They also went through CNC processing that ensured tight fit and prevented screwdriver bit options from CAM-out. 

The only downside for this product is it only includes three nut drivers. But honestly, for most of your basic tasks, that should suffice. And hey, it comes with a storage case, which makes organization a lot easier.

6. Makita A-98348 50-pc ImpactX Driver Bit Set

For those willing to invest a bit more for quality and variety, I’d recommend giving the Makita A-98348 ImpactX Driver Bit Set a look. Constructed from S2 steel, this set isn’t just durable; it’s built to withstand heavy-duty work environments. 

This ImpactX Driver Bit Set comes with a manganese phosphate surface, making it more likely to resist corrosion than other options. Its optimal geometry also features secure slots that give each bit enhanced holding power. 

Perhaps one of the more underrated features is the magnetic extension rod. If you’re like me and find yourself in tight corners more often than you’d like to admit, this rod allows for more control in those tricky, hard-to-reach spaces.

7. BOSCH SDMS44 Impact & Screwdriver Bit Set

Another premium impact & screwdriver bit set you can buy for a slightly higher price range is BOSCH SDMS44. Unlike typical carbon steel bits, this kit includes alloy steel attachments, which are known to be tougher and stronger. 

Organizing these bits won’t be a headache either. They come with silver sleeves and laser markings, making size identification a breeze.

The durable case for these bits is highly customizable, making it the best impact driver kit for serious DIYers. You can arrange the attachments according to your needs for more convenience during usage.

Impact Driver Bit Sets Buyer’s Guide

Bit Quantity and Variety

When you shop for the best impact driver bit set, you’ll find products packed in a kit of 5 pieces up to 50 pieces. In some cases, you’ll even encounter ones sold at 300 pieces. 

From what I’ve seen, it’s essentially useless to buy a set with a massive amount of bits if you’re a casual DIYer with limited access to power tools and materials. This scenario is especially true if you’re only tackling home repair jobs. 

Driver bit sets with more pieces are more in the ally of professional woodworkers and constructors. You can make do with 40 to 50 pieces of different bits for large-scale projects. If you’re looking for replacement bits, you can opt for a pack of 5 or 10.

Material Durability

I can’t stress enough how important durability is when picking a bit set. These bits are meant to attach with powerful tools, so getting ones that can stand against high torque is crucial. In all the sets I’ve tried and tested, the most reliable ones are typically made from top-notch materials like S2, carbon, and alloy steel.

Investing in a bit set with superior material durability not only guarantees reliable performance but also saves you from frequent replacements, making it a wise choice for both professionals and DIY enthusiasts seeking long-lasting and reliable tools.

And a pro tip—look for bits that have undergone heat treatments or have steel cores and protective coatings. These materials are more likely to protect the bits from corrosion and prolong tool life. 

Casing

Remember that these bits are small, so finding cases where you can organize them easily is a consideration you can’t skip. It should be able to keep the bits together despite any movement. 

Magnetic Holders

Magnetic holders are a godsend, especially if you’re a beginner. From my experience, having these magnets in your bit set helps you reach those tricky, tight spots without breaking a sweat. They securely hold the bits in place, making it easier to focus on the task.

Accessories

It’s not mandatory for an impact driver bit set, but it’s nice to have onboard nut drivers in the inclusions. Accessories like magnetic extension tips will also come in handy if you try to get into tight spaces. Through this feature, the bit will stay in place. 

Process of Manufacturing

The demand for these materials has escalated, so the CNC-machining process became their standard manufacturing process. Despite its precision, it doesn’t mean the driver bits produced today are perfect.  

Corrosion and Torque Resistance

Corrosion can be a major headache, especially when you’re dealing with steel bits. If you’re like me and want to prolong your bits’ life, aim for those with protective coatings.

These bits should also show no weakness or break under high torque. Make sure you opt for bits that can handle at least 2000 pounds of torque to prevent breakage or worse, accidents. Safety first, always.

Applications

It’s cost-efficient to buy sets that cater to drills and impact drivers. Even if you’re just a home user, furniture installations and other maintenance tasks require different bits.

Set Organization

Organizing these bits should be the top priority to avoid wasted time and increase efficiency. Here are the features that will help you achieve this:

Slots

If you’re often in transit from one jobsite to another, I advise get a case with secure slots. By doing so, the bits won’t fall out during transportation. Digging through messy and disorganized bit pieces will result in a longer process and frustration. 

Markings

While some sets only include markings on the case, some options include this feature on the bit pieces. It’s an effective solution if you want an organized bit set.

Extra Features

While these additional features aren’t crucial requirements, they’re nice to have because they make everything more convenient and efficient. 

  1. Drive Guide – prevents wobbling during screw installations.
  2. Quick-change System – for faster tool insertion and extraction.
  3. Non-sparking Bits – No sparking effect when in contact with stone or metal.

FAQ

What do you mean by “CNC”?

CNC machining refers to the computer program that determines if the driver bit pieces meet the required specifications set by the manufacturer. Since it’s an accurate system, it ensures durability and prevents CAM-out. 

Will I need Dewalt bit sets for a Dewalt impact driver?

Regardless of the brand, if the specifications match, you can use bit sets for an impact driver under a different manufacturer. 

Can I use magnetic bits on my cordless impact driver?

Magnetic bits like Phillips and Torx will work well with a cordless impact driver.  

Can I use bits on damp surfaces?

Using bits on damp surfaces can be dangerous. If you can, always ensure that the wood, plastic, or metal surface are dry before any operation. Moisture exposure can lead to a faster corrosion effect. 

How many should I have in an impact driver set?

A few bits should be enough as long as it includes the bits you need for your project. I don’t recommend anything more than 90 pieces, especially if you’re a casual home user.

My Top Pick For an Impact Driver Bit Set:
DEWALT DWA2T40IR FlexTorq

When it comes to impact driver bit sets, I’ve found that many are similar in price and features. However, the DEWALT DWA2T40IR FlexTorq emerged as the best impact driver bit set on the list.

This kit isn’t as massive as others, but it includes standard bit pieces you’ll need in regular tasks. It’s also easy and convenient to use, making it the ideal choice for professionals and beginners.
