Metal drilling asks for the right bit, not just a sharp one. You need a set that starts cleanly, stays steady in a hand drill or press, and matches the material in front of you, whether that’s sheet metal, stainless, wood, or plastic. The right set saves time, reduces wandering at the start, and keeps your work cleaner. The wrong one turns a simple hole into a slow, noisy chore.

Who It Suits Best
Home fixers and weekend tinkerers who want a familiar, general-purpose set will get the most out of this one.
A Better Fit Elsewhere
IRWIN M35 Cobalt Drill Bit Set 29-Piece (3018002) suits you better for tougher metals and more heat-heavy drilling.
This IRWIN set moves up a step for harder material work, thanks to M35 cobalt alloy steel. Cobalt content is valued because it tends to hold up better under heat, so you may find it more comfortable for repeated drilling in steel than the plain high-speed steel set above.
The 1/16-inch to 1/2-inch range in 1/64-inch increments gives you very fine sizing control, and the 135-degree split point helps the tip start with less wandering. That matters in metal, where a bit that skates can waste time and mark the work.
What We Like
- M35 cobalt alloy steel suits harder, hotter drilling jobs.
- 1/64-inch steps give you unusually fine size control.
- 135-degree split point helps the bit start cleaner.
- 29 pieces cover a broad range without feeling sparse.
Room For Improvement
- More capable metal drilling usually means more care with storage and edge protection.
- The tighter sizing range can feel unnecessary for very simple wood-only work.
Technical Sheet
Who Will Love This
You get the most from this set when your projects lean toward steel, brackets, and other harder surfaces.
Swap It Out When
IRWIN Drill Bit Set 29-Piece (3018005) is the easier pick for lighter general-purpose jobs and simpler maintenance.
The black-and-gold finish gives this CaRoller set a more polished look than the plain steel sets above, but the useful part is the 135-degree tip. That angle can help the bit bite faster and cut down on skating, which is handy in stainless, plastic, or thin stock where the start point matters.
For mixed home work, this feels like a tidy middle ground. The indexed case also helps keep sizes organized, so you spend less time searching through loose bits after a project is done.
Positives
- 135-degree tip helps the bit start more cleanly on hard surfaces.
- Black-and-gold coating gives the set a more finished look.
- Indexed storage case keeps sizes easier to sort and return.
- 1/16-inch to 1/2-inch coverage handles many common tasks.
Softer Spots
- The finish adds style, but it does not change the job on its own.
- Like many busy multi-piece kits, the case deserves careful closing and storage.

Where A Sibling Pick Shines
DEWALT Titanium Nitride Coated Drill Bit Set with Pilot Point, 29-Piece (DW1369) suits you better for a more guided start and a slightly more purpose-built feel.
This CaRoller set shifts from general-purpose steel toward M35 cobalt steel, which is the kind of change that matters once your projects spend more time in steel or sheet metal. The round shank keeps the fit familiar in standard drill chucks, and the included cup-style holder gives you a simple place to park the bits.
Compared with the black-and-gold CaRoller set, this one reads more workmanlike and less decorative. That makes sense for shop cabinets, toolbox storage, and users who care more about holding up under tougher jobs than about finish color.
Bright Spots
- M35 cobalt steel is a stronger match for tougher drilling conditions.
- Round shank works with common drill chucks.
- Cup-style holder gives the set a straightforward storage spot.
- 29-piece spread offers solid size coverage for regular shop use.
- Good fit for steel, wood, plastic, and sheet metal tasks.
Points To Note
- The holder is practical, but loose bits still need tidy storage habits.
- Harder-metal sets can feel a touch less casual for simple weekend work.

The Right Fit
This works best for anyone drilling steel often enough to want a sturdier, more focused set in the toolbox.
A Better Fit Elsewhere
IRWIN Drill Bit Set 29-Piece (3018005) is the gentler match for lighter all-purpose use and less demanding storage needs.
This DEWALT set stands out because of the pilot point, a tip design that helps the bit start where you want it instead of wandering across the surface. Titanium nitride coating is the other key part here, and that finish is commonly used to improve wear resistance during repetitive drilling.
In a busy workshop, that combination can feel reassuring. It’s a strong fit for users who want cleaner starts in metal and fewer little annoyances while switching from one size to the next.
Upsides
- Pilot point design supports cleaner starts on many surfaces.
- Titanium nitride coating adds a more durable working finish.
- 29 pieces give you broad coverage for common tasks.
- Useful for metal, wood, and plastic projects without much fuss.
Areas To Watch
- Coated bits still need sensible storage so edges stay protected.
- The set is better suited to careful drilling than rough, improvised work.

Built With In Mind
Careful DIY work, cabinet hardware, and tasks where start accuracy matters are the best match here.
Another Choice May Suit
CaRoller Cobalt Drill Bit Set 29-Piece (29pcs Cobalt) is the better call for you when the material is tougher and the job leans heavier.
This Milwaukee kit is smaller than the 29-piece sets, so it makes more sense for portable tool bags and pared-down jobs. The TiN finish, meaning titanium nitride coating, is the feature to focus on, and the Shockwave line is usually aimed at users who want a tougher-feeling bit set for regular work.
That smaller count is the trade-off, of course. You get less size coverage than the full-size IRWIN and CaRoller sets, but the lighter footprint can be a real advantage for contractors or handypeople who move between sites.
Best Bits
- Compact 15-piece size keeps the kit easy to carry.
- Titanium nitride coating adds a more durable surface treatment.
- Useful for tool bags where space matters.
- Good match for mobile, task-focused drilling.
Worth Noting
- Fewer pieces mean less size coverage than the 29-piece sets.
- Storage becomes more important because smaller kits are easier to misplace.
Feature Rundown
Perfect Match For
You’ll appreciate this most on mobile jobs, repair calls, and tight tool-bag setups where every ounce of space counts.
Look Elsewhere When
DEWALT Titanium Nitride Coated Drill Bit Set with Pilot Point, 29-Piece (DW1369) is a better fit for you when broader sizing and a guided start matter more than compactness.
Hex shanks are the big convenience here, because they grip quickly in compatible drivers and help reduce bit slip in quick-change setups. The 4241 high-speed steel base and titanium coating make this a sensible compact kit for light metal, wood, and plastic work around the house.
Compared with the Milwaukee kit, this AUYAARS set gives you a broader size spread in a different style of drive, but it still stays on the smaller side. That makes it useful for cordless-driver owners who want fewer steps between grabbing the tool and making the hole.
Highlights
- Hex shanks work well with quick-change drivers.
- 4241 high-speed steel fits light to moderate drilling.
- Titanium coating adds a more wear-conscious surface.
- Compact 19-piece layout keeps the kit manageable.
Small Caveats
- Size coverage stops at 1/4 inch, so bigger holes need another tool.
- Driver-friendly bits can feel less universal than standard round-shank sets.

Whose Shelf It Belongs On
You’ll get the most from this set when you use a driver often and want quick changes without carrying a bulky case.
Reach For A Different Pick When
IRWIN M35 Cobalt Drill Bit Set 29-Piece (3018002) is the better choice for tougher metal work and finer size control.
This AIMLENTOOL set goes in a different direction from the twist-bit kits above. Step drill bits are shaped to widen a hole in stages, and countersink bits are used to create a tapered seat for screw heads, so the set is more about shaping and finishing than basic boring.
The aluminum case makes sense for a kit with this many roles, because organization becomes part of the value. For sheet-metal DIY, that mix can be handy, although it’s less of a one-size answer than a straight 29-piece twist set.
Reasons To Buy
- Step bits handle staged hole enlargement with less switching.
- Countersink bits help prepare cleaner screw seats.
- Titanium coating supports regular use on metal.
- Aluminum case keeps the assorted pieces together.
Minor Gripes
- The specialty layout suits finishing work more than general drilling.
- Managing two bit types takes a little more organization.

IRWIN Drill Bit Set 29-Piece (3018005) is the simpler fit for basic drilling without specialty step and countersink pieces.
How To Choose The Right Drill Bit Sets For Metal
Material First, Then Finish
Start with the bit material, because that decides how the set handles heat and wear. High-speed steel works for ordinary tasks, while cobalt alloy steel is a stronger match for harder metals and longer sessions. Titanium nitride or titanium coating can help surface durability, but the base material still does most of the real work.
Match The Shank To Your Tool
Round shanks fit standard chucks and suit most hand drills and presses. Hex shanks are more convenient in quick-change drivers, which is useful for install work or repeated bit swaps. The right shank saves time every time you switch tasks, and that matters more than many shoppers expect.
Pay Attention To Tip Geometry
Split points and pilot points help the bit start with less skating on metal. That matters most on slick surfaces, painted sheet, and thin stock where the tip can wander before it bites. A 135-degree split point often feels more controlled than a basic point, especially for anyone drilling by hand.
Think About The Whole Kit, Not Just The Number Of Pieces
A 29-piece set is handy for broad coverage, but a smaller 15-piece kit can be easier to carry on site. Step bits and countersink bits solve different problems from twist bits, so they make sense for finishing work instead of everyday hole making. The best set is the one that fits the kind of metal work you actually do, not the one with the longest list of pieces.
What To Weigh Before You Click
Hidden Buying Traps
Many shoppers focus on piece count and skip the bit material. That leads to sets that look complete but wear out too soon for the metal they’re meant to handle.
Another common miss is ignoring shank style. A well-made hex set can still be awkward in a standard drill press, while a round-shank set may feel slower in a quick-change driver.
The Upgrade Payoff
Higher-tier sets usually cost more because of the steel blend, coating, and tip design. Cobalt, TiN coating, and better point geometry tend to add durability, better starts, and less frustration on repeat jobs.
That upgrade makes sense for steel work, frequent use, and anyone who hates redoing a hole after a wandering start. For light occasional drilling, a simpler high-speed steel kit is often enough.
Frequently Asked Questions
What kind of drill bit works best on metal?
High-speed steel is a solid starting point for general use, while cobalt alloy steel suits harder metals better. Tip shape matters too, because split points and pilot points help the bit stay put at the start.
Do coated bits last longer?
Coatings like titanium nitride can help the surface handle wear more comfortably. The coating helps most when the base steel is already matched to the job.
Should you choose hex shank or round shank?
Hex shanks work well in quick-change drivers and speed up swaps. Round shanks are more universal in standard drill chucks and feel familiar in many home shops.
Are larger sets always the better choice?
Not always, because size only helps when the included range matches your work. A smaller, well-chosen kit can be easier to store and faster to use.
Why pick step bits instead of twist bits?
Step bits are useful for enlarging holes in stages, especially in sheet metal. Twist bits are better for standard drilling and more general-purpose hole making.
Final Thoughts
The right drill bit set for metal comes down to the surfaces you handle most and the tool you reach for every day. IRWIN’s cobalt set makes sense for harder work, while the simpler IRWIN high-speed steel kit stays friendly for routine jobs. DEWALT leans toward cleaner starts, Milwaukee helps when portability matters, and the AIMLENTOOL set covers shaping as well as drilling. Choose the one that matches your actual workbench habits, and the rest gets easier.
