Best Selling 5 Dewalt Bit and Drill Set
I’ve found that the hard part isn’t finding a big bit set, it’s finding one your existing drill can actually use. That’s why our best dewalt bit and drill set pick centers on fit, not sheer quantity. A screwdriver bit set is a collection of driver tips, not a complete drill package, so DEWALT ToughCase, FlexTorq and 20V MAX labels need careful reading.
Our research ranks the Tough Grip 120-Piece Screwdriver Bit first for its 120-piece selection. If you need the drill included too, the 20V MAX Drill/Driver Kit is the stronger starting point. Start with the winner below, then use the quick comparison to choose your setup.

List of Top 5 Best Dewalt Bit and Drill Set
I compared the five sets on shank fit, piece count, included accessories and how well each supports assembly, repair or drilling. The first four are bit collections rather than complete drills, and that distinction matters. Each section explains what you gain, where the gaps are, and who should choose it.
Below are the list of products:
1. Tough Grip 120-Piece Screwdriver Bit
In our research, the DWAF120SETTG set stands out for selection, with 120 pieces built around a 1/4-inch hex shank. It’s the broadest driver-bit option here, though it is a bit collection rather than a cordless drill package. That distinction makes it most useful when you already own a compatible tool.
Why I picked it
I rank it first because 120 pieces give you a much wider assortment than the 14-piece drilling set. Manufacturer specifications indicate a 1/4-inch hex shank, alloy steel construction and impact-ready construction, which makes this a sensible foundation for mixed household repairs. The deciding factor isn't the biggest number, though.
You need a tool that actually accepts the shank.
Key specs
- 120-piece screwdriver bit assortment
- 1/4-inch hex shank
- Alloy steel construction
- Impact-ready designation
- Model identifier: DWAF120SETTG
Real-world experience
Picture a weekend of assembling shelving, attaching cabinet hardware and replacing fasteners around the house. A 1/4-inch hex chuck or a compatible driver holder lets you use these bits across those jobs, but you still need the tool. Check the individual tip markings before using any part in an impact tool, since impact-ready labeling does not mean every accessory is interchangeable.
- 120 pieces give you a broad selection for assembling furniture, hanging hardware and everyday household repairs.
- Alloy steel construction provides a useful material specification when you want more than a random assortment of small tips.
- The impact-ready designation suits compatible high-shock applications, provided you check the tool and bit requirements.
- The 4.8/5 reported rating makes this a strong shortlist candidate for an existing compatible tool.
- The 1/4-inch hex shank needs a compatible chuck or driver, so check your tool before ordering.
- No drill is included, and a 120-piece assortment needs sensible storage if you want every size easy to find.
- ✔ You want a large driver bit assortment for household projects.
- ✔ Your drill or driver accepts a 1/4-inch hex shank.
- ✔ You need a broad collection rather than drilling-focused bits.
- ✖ You need a complete cordless drill package.
- ✖ You only need a small number of specific drill bit sizes.
2. Drill Bit 3-Flats Shank 14-Piece 135
A drill bit is a cutting tool that makes holes, and this 14-piece DWA1184 set is built for that job rather than general screwdriving. It combines a 3-Flats shank with a 135-degree split point for plastic, wood and metal. It's the right choice when you want more drilling options, not another oversized driver assortment.
Why I picked it
I rank this set highly when the job involves making holes across several materials. Its 135-degree split point is designed to help the tip start without the normal center point, while the 14-piece count keeps the assortment manageable. You still need to match the 3-Flats shank to your drill.
Key specs
- 14-piece drill bit set
- 135-degree split point
- 3-Flats shank
- Intended for plastic, wood and metal
- Model identifier: DWA1184
Real-world experience
This set makes more sense for adding shelves, building a simple wooden frame or creating pilot holes before driving screws. A 135-degree split point helps the bit start more cleanly than a conventional full-point tip, which is useful when accuracy matters. Compared with the 120-piece screwdriver set, you're giving up broad driver coverage for a much more focused drilling toolkit.
- The 135-degree split point helps you start drilling with less walking across the surface.
- The 14-piece format gives you a practical selection without the bulk of a 100-piece or 120-piece case.
- Intended use includes plastic, wood and metal, which makes it useful for mixed household projects.
- The 4.8/5 reported rating supports its place as a focused drilling pick.
- The 3-Flats shank needs a compatible chuck or collet, so don’t assume it fits every drill.
- The set is for drilling, so it isn’t a replacement for a broad screwdriver bit assortment or a cordless drill.
- ✔ You mostly need drill bits for wood, plastic or metal.
- ✔ You want a split-point design for cleaner starts.
- ✔ You prefer a focused 14-piece set over a larger accessory case.
- ✖ Your main need is driving a wide variety of fasteners.
- ✖ You don’t have a drill that accepts the 3-Flats shank.
3. Screwdriver Bit Tough Case
A screwdriver bit is a shaped driver tip that transfers torque to a fastener, and this DW2166 set gives you 45 of them in a tough case. I treat it as the sensible budget option for everyday assembly and repairs. The lower piece count can mean fewer extras to sort through, but you need a compatible tool.
Why I picked it
I pick the DW2166 when the priority is a practical driver assortment without paying for every extra size in a larger case. A 45-piece set is easier to keep organized than a 120-piece collection, and the named tough case gives the bits a home. The trade-off is narrower coverage when you regularly work with unusual fasteners or need specialist impact-rated tips.
Key specs
- 45-piece screwdriver bit set
- Tough case included
- Grey and silver set designation
- Model identifier: DW2166
- Reported rating: 4.8/5
Real-world experience
A 45-piece screwdriver set like this suits a home repair kit, whether you're assembling flat-pack furniture, tightening a loose hinge or handling common household fixings. The case is the detail that matters when you want one place for loose bits, not a handful rolling around a drawer. If your priority is metal drilling or a larger impact-ready inventory, this is the more restrained choice.
- 45 pieces provide a useful middle ground between a small add-on and a 100-piece or 120-piece collection.
- The included tough case gives your bits a designated storage place.
- The DW2166 designation helps you compare the exact model rather than relying on a vague bit-set description.
- The 4.8/5 reported rating makes it a credible pick for routine home repairs.
- It includes bits rather than a drill, so you need a compatible driver or drill chuck already.
- The 45-piece inventory cannot offer the same specialist coverage as a larger 100-piece or 120-piece set.
- ✔ You want a practical home repair set without a 120-piece assortment.
- ✔ Keeping bits together in a tough case matters to you.
- ✔ Your main tasks involve everyday screwdriving.
- ✖ You need a cordless drill included in the purchase.
- ✖ You rely on a large inventory of impact-ready, nut-driver or drill-bit accessories.
4. Screwdriver Bit 100 Pc Impact Driver
I treat DWA2FTS100 as the most balanced large accessory set when you move between driving fasteners, turning nuts and making ordinary holes. It includes 100 pieces, a magnetic holder, nut drivers, drill bits and a ToughCase. FlexTorq is a DEWALT impact driver bit line, which makes tool compatibility a more important buying question than the count alone.
Why I picked it
I rank this fourth because the mix matters more than the round number: 100 pieces cover several kinds of work without moving you into a larger assortment. It’s a good fit when you want a magnetic holder, nut drivers and drill bits in one case. Tool compatibility is the main caveat, not the selection.
Key specs
- 100-piece accessory set
- FlexTorq impact-ready bits
- Includes drill bits
- Includes nut drivers
- Includes a magnetic holder
- ToughCase storage, model DWA2FTS100
Real-world experience
This set suits a mixed toolkit that handles furniture assembly, light drilling and occasional nut-driving. The ToughCase also gives each piece a designated place, which matters more with 100 accessories than a loose handful of bits. For impact work, use FlexTorq bits in a compatible impact driver; conventional drill bits from the same case aren't interchangeable impact-driver accessories.
- One 100-piece case combines driver bits, drill bits and nut drivers, so fewer separate sets are needed.
- The included magnetic holder gives you a practical way to group compatible bits at the workbench.
- ToughCase storage helps keep an extensive assortment organized between projects.
- The 4.7/5 reported rating supports a versatile pick for mixed accessory needs.
- A 100-piece assortment takes more sorting than a 45-piece set, so clear labels matter.
- The case still needs a separate drill or driver, and the title doesn’t mean every accessory fits an impact tool.
- ✔ You drive fasteners, turn nuts and drill small holes.
- ✔ You want a magnetic holder and organized storage.
- ✔ You own tools compatible with the included bit types.
- ✖ You need a ready-to-use cordless drill and battery.
- ✖ You want the smallest possible collection for basic home repairs.
5. 20V MAX* Cordless Drill/Driver Kit Screwdriver/Drill
A cordless drill/driver combines drilling and screwdriving in one motor-driven tool. This DCD771C2 package includes that tool and the 100-piece DWA2FTS100 accessory set, so it's the only complete drill-and-bits bundle on our list. Its 4.9/5 reported rating makes it a strong starting point, provided you don't already own a suitable 20V MAX tool.
Why I picked it
I pick this last because it solves the biggest gap in the other four: none includes a cordless drill/driver. You get the DCD771C2 plus the DWA2FTS100 collection, which covers basic drilling, driving and several accessory types. If you already have that battery platform, buying only the bits is the more efficient choice.
Key specs
- DCD771C2 cordless drill/driver
- 20V MAX battery platform
- Includes the DWA2FTS100 100-piece set
- Driver bits, drill bits and nut drivers
- Magnetic holder and ToughCase storage
- Reported rating: 4.9/5
Real-world experience
This package makes sense for a new DIY setup, a first apartment toolkit or someone who needs one purchase to cover shelves, furniture and basic repair jobs. You still need compatible 20V MAX batteries and a charger to use the cordless tool, so read the package contents before assuming everything needed is included. A separate impact driver is a different purchase, and that distinction matters for high-shock driving.
- You receive both a cordless drill/driver and a 100-piece accessory set, reducing the need for separate starter purchases.
- The 20V MAX platform gives you a recognizable battery family to check before building a larger DEWALT toolkit.
- The accessory set covers driver bits, drill bits and nut drivers in a ToughCase.
- The 4.9/5 reported rating is the highest of the five products.
- Confirm the charger, batteries and other package contents before ordering, because the title doesn’t enumerate them.
- The drill/driver does not replace an impact driver for high-shock fastening, and the bundle is bulkier than a bits-only set.
- ✔ You’re building a first cordless DIY setup.
- ✔ You want a drill/driver and a broad accessory case together.
- ✔ You plan to use compatible 20V MAX batteries.
- ✖ You already have a compatible cordless drill/driver.
- ✖ You need a standalone impact driver for demanding fastening work.
How I picked
I built this ranking around manufacturer specifications, the components each package actually includes and the practical gap it fills in a toolkit. A large number of pieces can look impressive, but it doesn't help if the tool doesn't accept the shank or you only need three sizes.
I compared the products using four checks:
- Tool fit: Shank type, whether the accessory is intended for drilling or driving, and whether the package includes a drill.
- Job coverage: Driver bits, drill bits, nut drivers, magnetic holding and ToughCase storage.
- Practical balance: Whether the assortment suits routine home repairs, a new toolkit or mixed maintenance work.
- Buyer evidence: Reported ratings of 4.7/5 to 4.9/5, alongside manufacturer descriptions, rather than treating stars as proof of lifetime durability.
I didn't run an independent 60-day wear test, measure tip hardness or check performance under impact loading. I also didn't assume the exact contents of the 20V MAX kit beyond the drill and 100-piece set stated in its title. Warranty duration, individual bit dimensions and battery inclusion still need checking in the current listing.
That distinction matters: the ranking favors useful coverage and clear tool requirements, not an unsupported promise that one set will last forever.
Buying guide — what actually matters for dewalt bit and drill set
Are you buying drill bits or screwdriver bits?
A screwdriver bit set fits fasteners; a drill bit set cuts holes, and one rarely replaces the other. The DWAF120SETTG, DW2166 and DWA2FTS100 titles emphasize screwdriving, while the DWA1184 is a focused 14-piece drilling set. If you already have both a drill and driver, prioritize the missing accessories rather than buying another broad collection.
How do you match a 1/4-inch hex shank?
A shank is the shaft that connects a bit to a chuck, socket or driver. The DWAF120SETTG uses a 1/4-inch hex shank, so the receiving tool must be designed for that connection. A 3-Flats shank is a different fit, and a DEWALT logo alone doesn't guarantee compatibility with every chuck.
You sacrifice some flexibility when you buy a tightly matched specialist set, but you reduce the guesswork.
What does a 135-degree split point change?
A split point is a cutting tip that divides into two contacting points instead of using a full center point. The DWA1184's 135-degree split point is designed to start with less walking across the work surface, which is useful for controlled drilling. A 14-piece set can cover a focused project better than a 120-piece set full of sizes you won't use.
Choose it when making holes is the main task, not general assembly.
Does “impact ready” mean every bit works in an impact driver?
No. Impact-ready labeling only helps when the tool and the individual bit are both rated for impact use. The DWA2FTS100 includes FlexTorq impact-ready bits, but that doesn't make every drill bit or nut driver in the case an impact-driver accessory.
In 2026, checking the exact model number is more dependable than assuming a shared DEWALT name means universal compatibility.
Is a 45-piece, 100-piece or 120-piece set better?
A larger set gives you more choices, but a smaller case can be easier to organize and cheaper to replace. The 45-piece DW2166 fits routine household driving, the 100-piece DWA2FTS100 covers a broader mix of tasks, and the 120-piece DWAF120SETTG leads on driver assortment. Prioritize the sizes and accessories you actually need, not the biggest printed number.
When does a 20V MAX kit make more sense?
DEWALT 20V MAX is a cordless battery platform, so a drill and compatible batteries must be treated as one system. The DCD771C2 and DWA2FTS100 package is most useful for a first setup or a replacement drill with accessories. If you already own a suitable 20V MAX tool, check DEWALT's official product information for the exact model before buying the full bundle.
Frequently Asked Questions (FAQ)
Are all DEWALT bit sets compatible with DEWALT cordless drills?
No, the DEWALT name doesn't guarantee that every bit fits every drill. A 1/4-inch hex driver bit, a 3-Flats drill bit and a FlexTorq impact bit have different connection requirements. The DCD771C2 kit avoids some guesswork because the tool and accessory set are presented together, while the standalone sets need a compatibility check.
Can a 1/4-inch hex bit fit any DEWALT drill?
It can fit a drill with a compatible 1/4-inch hex chuck, not simply any DEWALT drill. You also need enough chuck capacity for the bit's full shank. The DWAF120SETTG is therefore a good match for a suitable existing tool, but less attractive if you need a whole new cordless setup.
Is a 45-piece or 100-piece bit set better for home repairs?
The 45-piece DW2166 is a focused choice for everyday screwdriving, while the 100-piece DWA2FTS100 adds drill bits, nut drivers and a magnetic holder. Choose 45 pieces if you want less to sort through and already have drilling covered. Choose 100 when your projects genuinely span several kinds of fastening and drilling tasks.
Will the DWAF120SETTG work with an impact driver?
Only when the impact driver and the individual bit are both compatible with that use. The set's impact-ready designation is encouraging, but it isn't permission to put every accessory in an impact tool. Check the tool's bit requirements and the markings on the specific tip before using it for high-shock driving.
Do I need a ToughCase or a full cordless drill kit?
Choose ToughCase storage when you already own a suitable tool and want the bits organized. Choose the 20V MAX kit when you need the DCD771C2 drill/driver and a broad accessory set together. ToughCase is storage, not a battery system, and a bits-only purchase doesn't include the cordless tool you need to use it.
Final verdict
The Tough Grip 120-Piece Screwdriver Bit is the best overall pick for broad driver coverage, provided your tool accepts its 1/4-inch hex shank. For a complete new setup, choose the 20V MAX Drill/Driver Kit; for routine home repairs, the 45-piece DW2166 is the more restrained alternative.
