You want drill bits that match the job, not just a crowded case that looks useful on a shelf. The right set saves time on wall anchors, furniture assembly, deck work, and those awkward repairs where a bit that wanders or dulls too fast turns a quick task into a slog.
This roundup focuses on sets that make sense for home projects, shop use, and everyday toolboxes. You’ll see lean 29-piece drill-bit sets, larger mixed kits, and a few upgrade-worthy options for tougher materials, so you can match the set to how you actually work.

More Details On Our Top Picks
IRWIN keeps this set straightforward, which helps more than flashy extras usually do. The high-speed steel build suits common drilling jobs in wood, plastic, and lighter metal, so you’re not juggling a pile of specialty bits for ordinary home repairs.
For a garage toolbox or a first drill-bit case, that simplicity is the point. The trade-off is clear, though, since a basic 29-piece HSS set is more about broad everyday coverage than heavy-duty metal work.
Strong Points
- High-speed steel suits everyday drilling needs.
- 29-piece spread covers common sizes cleanly.
- Good fit for keeping one simple case nearby.
- Works well for basic home maintenance tasks.
Things To Consider
- Basic HSS construction is less suited to harder metal jobs.
- You may outgrow it sooner in a busy workshop.
- Storage is simple rather than feature-heavy.
Feature Snapshot
Who It Suits Best
Homeowners and casual DIYers who want a plain, dependable drill-bit case will get the most value here.
Where A Sibling Pick Shines
IRWIN Drill Bit Set, M35 Cobalt 29-Piece (3018002) is the stronger call for more metal-heavy work, especially when harder stock is part of your week.
The cobalt alloy steel here changes the feel of the set right away, because that material is aimed at tougher, hotter drilling conditions than basic HSS. The 135-degree split point helps the tip start more cleanly and stay put better on the mark, which matters a lot on slick metal surfaces.
That makes this a stronger match for garage work, fabrication tasks, and regular drilling into harder stock. The trade-off is that a cobalt set is more purpose-built, so it makes less sense as a casual, all-purpose kit than the first IRWIN set.
What We Like
- Cobalt alloy steel is a better fit for harder materials.
- Split-point tip helps reduce wandering at the start.
- 29-piece range keeps the set practical, not oversized.
- Good step up from a basic home kit.
- Useful for frequent metal drilling around a shop or vehicle.
Points To Note
- More specialized than a plain HSS set.
- Still a 29-piece case, so it is not the broadest option.
- Metal work can wear any bit set faster, so storage care matters.
Core Details
Who Will Love This
You should look here for routine metal drilling, hardware installs, and shop use where a tougher bit set makes sense.
Look Elsewhere When
Norseman Drill Bits 44170 Ultra Dex Type 240-UB 29-Piece suits you better when a more refined pro-shop feel matters than raw value.
Norseman’s Ultra Dex name usually signals a more workshop-minded approach, and this set fits that impression well. The 135-degree split point is the practical detail that stands out most, because it helps the bit bite without skating across the work surface.
That is useful in a busy shop where repeat drilling, cleaner starts, and a steadier feel matter more than a flashy case. Compared with the two IRWIN sets, this one leans more premium in attitude, but the narrower 29-piece layout keeps it focused rather than sprawling.
Best Bits
- Split-point design helps with more controlled starts.
- Feels suited to regular shop use.
- 29-piece count keeps the set easy to store.
- Good choice for work where bit alignment matters.
Honest Caveats
- Not the most expansive kit in this roundup.
- May be more than a casual weekend toolbox needs.
- Premium-leaning sets usually deserve a tidier storage habit.

Best Suited To
Serious DIYers and small-shop users who want a cleaner-starting drill-bit set will feel at home with this one.
A Better Fit Elsewhere
SKIL 120pc Drilling and Screw Driving Bit Set SMXS8501 makes more sense for a household that wants one larger mixed case instead of a dedicated drill-bit set.
SKIL goes in a different direction from the first three picks, because this is a mixed drilling and screw-driving kit rather than a focused drill-bit case. That makes it appealing in a household toolbox, where you want one set to cover assembly jobs, light repairs, and the occasional hole-drilling task.
The larger 120-piece spread gives you more reach across common fasteners and bit types, but it also means a busier case. For people who mainly want dedicated drill bits, the compact IRWIN and Norseman sets stay cleaner; for households that want one broad kit, SKIL makes more sense.
Highlights
- Large 120-piece set covers many routine tasks.
- Good fit for home assembly and general repairs.
- Bit grip adds practical handling convenience.
- One case can replace several small boxes.
Areas To Watch
- Not a dedicated drill-bit-only package.
- The larger case can feel busy to sort through.
- Household storage works best when pieces stay organized after use.
Feature Rundown
Whose Shelf It Belongs On
Households, apartment tool kits, and new homeowners who want a broad bit assortment will get the most from this set.
Swap It Out When
IRWIN Drill Bit Set, M35 Cobalt 29-Piece (3018002) is the sharper fit for you when your projects lean harder into metal drilling than general fastening.
This SEDY kit is not a pure drill-bit set, and that matters because it serves a broader fastening role than the name of the roundup suggests. The mix of metric and SAE sizes, plus socket adapters, a bit holder, a wing nut driver, universal sockets, and a quick-release extension, makes it useful around vehicles, furniture, and packed tool drawers.
For a person who hates hunting through separate boxes for one fastener size, this sort of all-in-one layout feels practical. The compromise is obvious too, since a mixed fastening kit is less focused than a dedicated drill-bit set like the IRWIN or CaRoller options.
Positives
- Wide accessory mix covers many fastening tasks.
- Metric and SAE sizes add real shop convenience.
- Quick-release extension helps in tighter work zones.
- Good setup for car, furniture, and repair use.
Softer Spots
- Not the right pick for someone who wants drill bits first.
- Mixed kits ask for a little more sorting discipline.
- Broader coverage can feel less streamlined than a drill-only case.
Core Details
Perfect Match For
You fit this set best when your projects cover nuts, bolts, and assorted driver tasks more than drill holes alone.
Another Choice May Suit
CaRoller 29Pcs Drill Bit Set Black and Gold is the cleaner pick for a person who wants a drill-bit case with a more focused layout.
The black-and-gold finish gives this set a more polished look than the plain metal cases in the IRWIN lineup. Just as important, the metal indexed storage case keeps the pieces easier to sort, which helps when your workbench already has enough small parts lying around.
The 135-degree tip is a useful detail for cleaner starts, and the stated material mix points it toward everyday drilling in stainless steel, plastic, and wood. For light shop use or a tidy garage drawer, that combination lands in a very practical middle ground.
Bright Spots
- Metal storage case helps keep bits organized.
- Black-and-gold styling looks more finished on the shelf.
- 135-degree tip supports steadier starts.
- Useful for common household and light shop materials.
Room For Improvement
- Style is nice, but function matters more than color.
- Still a 29-piece kit, so coverage stays focused.
- Indexed cases work best when every bit gets returned to place.
Quick Facts
The Right Fit
You should look here for a compact drill-bit set that still feels a little more polished than the bare-bones basics.
Where A Sibling Pick Shines
CaRoller Cobalt Drill Bit Set 29-Piece M35 Cobalt is the smarter choice for heavier steel work, since its material is better aligned with tougher drilling.
This CaRoller set narrows in on the kind of work that pushes ordinary bits too hard. The M35 cobalt steel and round shank design are the notable pieces here, because they point toward steadier use on steel, wood, plastic, and sheet metal without making the set feel overly fancy.
The included cup-style holder is also useful in a real toolbox, since small bits are easy to misplace between jobs. Compared with the black-and-gold CaRoller set, this version feels more work-first and less about presentation.
Upsides
- M35 cobalt steel suits tougher drilling jobs.
- Round shank format is straightforward in use.
- Cup-style holder keeps the set easier to carry.
- Good everyday metal-drilling option without extra clutter.
Minor Gripes
- Storage is practical, not especially refined.
- 29 pieces keep the focus tight rather than expansive.
- Best results still depend on sensible bit care and cleanup.

Made For
Home mechanics and light-shop users who need a tougher drill-bit set for metal and mixed materials will be comfortable here.
Reach For A Different Pick When
IRWIN Drill Bit Set, M35 Cobalt 29-Piece (3018002) is a better fit for you when you want a more familiar major-brand path into cobalt drilling.
This is the biggest case in the group, so it speaks to people who like having plenty of sizes on hand. The M35 cobalt drill bits and metal index storage box point to a more serious toolbox role than the smaller 29-piece sets, especially for jobs that move across hardened steel, wood, plastic, and sheet metal.
For a busy garage or a shared workshop, that extra count helps you stay moving without stopping to hunt for a missing size. The trade-off is the usual one with large kits, namely more weight, more pieces to keep sorted, and more reason to return everything to the box after each session.
Reasons To Buy
- 115-piece size gives wide coverage for many jobs.
- M35 cobalt helps the set suit harder materials.
- Metal index box makes organization simpler.
- Good fit for garages, workshops, and shared tool storage.
Small Caveats
- Large kits take more space on the shelf.
- More pieces also mean more chances to misplace one.
- Better for users who actually need the size spread.
Core Details
Built With In Mind
You’ll get the most from this set in a workshop, garage, or maintenance cart where a large size range earns its keep.
Where Shoppers Go Wrong
Many people grab a 115-piece case for occasional weekend use, then find the extra bulk more annoying than helpful; the smaller CaRoller 29Pcs Drill Bit Set Black and Gold is the cleaner fit for lighter tool kits.
How To Choose The Right Drill Bit Sets
Match The Bit Material To Your Work
High-speed steel, often shortened to HSS, works well for general drilling in wood, plastic, and lighter metal. Cobalt steel, usually marked M35 in this roundup, belongs in a tougher lane because it handles hotter, harder drilling conditions better than plain HSS. That’s the main fork in the road: everyday convenience versus more confidence on metal.
For a home toolbox, HSS often covers enough ground without overpaying for capacity you won’t use. For garage work, vehicle projects, or repeated holes in steel, cobalt starts to make more sense. The honest read is that material choice matters more than fancy packaging.
Think About Set Size, Not Just Piece Count
A 29-piece case is tidy and easy to keep near the drill, which suits people who want a simple grab-and-go setup. Larger kits, like the 80-piece and 115-piece options here, trade compactness for broader coverage and fewer moments spent hunting for the right size. That can feel like a gift in a shared workshop and a nuisance in a cramped drawer.
Piece count alone can mislead you. A smaller, better-matched set often works better than a giant assortment that looks impressive but stays half unused. The set that fits your actual projects usually ends up feeling smarter.
Pay Attention To Tip Shape And Shank Design
A split point tip helps the bit start with less wandering, which is useful on metal and slick surfaces. Round shanks are the standard style for many drill chucks, while jobber bits remain the familiar all-purpose format for most household drilling. These details sound small, but they change how controlled the first second of drilling feels.
In a busy kitchen drawer fix or a garage shelf install, that control saves frustration. A steadier start also helps you avoid marring the surface before the hole even begins. That’s the kind of detail you appreciate more after the first off-center hole.
Look At Storage As Part Of The Purchase
Indexed cases, metal boxes, cup holders, and bit grips all affect how long a set stays useful after the first week. A good case keeps sizes visible, limits spills, and makes missing bits easier to notice before they vanish into the toolbox. That matters more than people expect, especially in shared spaces.
Storage also hints at the kind of use the set expects. A slim 29-piece case suggests focused work, while a bigger organizer points toward broader projects and more frequent handling. For most home users, the best choice is the one you can put back together without thinking too hard.
What To Weigh Before You Shop
Common Shopping Slip Ups
A lot of people focus on piece count and skip the material type, which leads to the wrong set for steel or repeated drilling. Another easy miss is buying a large mixed kit when the real need is a clean drill-bit case for routine work.
Storage gets overlooked too. A set that is hard to sort ends up annoying to use, even when the bits themselves are solid.
The Upgrade Payoff
Higher-tier sets usually cost more because of better materials, cleaner tip geometry, and cases that keep the assortment organized. Cobalt steel and split-point designs are the main reasons the price climbs in this category, since they support steadier starts and tougher materials.
The upgrade makes sense when you drill metal often, want fewer wandering starts, or need a larger size spread for repeated work. For occasional household use, a simpler HSS set can still be the more sensible call.
Frequently Asked Questions
What Is The Difference Between HSS And Cobalt Drill Bits?
HSS, or high-speed steel, is the common choice for general drilling. Cobalt, usually sold here as M35, is a tougher material for harder or hotter drilling jobs.
Do I Need A Large Drill Bit Set For Home Use?
Not always, because a compact 29-piece set can cover plenty of household jobs. Larger kits make more sense when you want broader size coverage in one box.
What Does A Split Point Tip Do?
A split point helps the bit start with less wandering at the mark. That makes it easier to begin cleanly on metal and other slick surfaces.
Are Mixed Bit Kits Better Than Drill-Only Sets?
Mixed kits help when you want one box for drilling and fastening tasks. Drill-only sets stay simpler and are usually easier to sort for people who mainly need holes, not drivers.
How Should You Store Drill Bits After Use?
Put each bit back in its labeled slot or holder so the set stays complete. That habit also makes it faster to spot a missing size before the next job.
Final Thoughts
Your best choice depends on how you actually work, not on how many pieces fit in a case. For simple household drilling, the IRWIN HSS set keeps things easy, while the M35 cobalt IRWIN and Norseman picks suit tougher material and steadier starts. SKIL and SEDY make more sense when your toolbox needs broader fastening coverage, and the two CaRoller sets fill the gap between compact organization and larger workshop reach. Pick the set that matches your space, your material, and how often you reach for it.
