Is it worth buying a set of drill bits if you only drill a few holes a month?
If you own a drill and you hang a shelf, tighten a loose bracket, or assemble flat-pack furniture a few times a year, you have probably stared at the bit aisle and wondered whether the cheap set in your hand is fine or a trap. The doubt is reasonable: a $12 set and a $60 set look almost identical in the package, and the difference only shows up after you have already spent the money. So here is the one question that decides everything for this category.

Will you actually use them more than a handful of times a year, and do you care how long each hole takes?

That is it. Drill bits are a consumable, not a tool you admire on a shelf. They wear out, they snap, they get dull, and the only thing that matters is whether the time and money you save beats the time and money you spend. For a household on a strict monthly budget, that math is not about brand loyalty. It is about cost per hole and minutes saved per week.
What it actually costs
Start with the purchase price. Budget sets of high-speed steel bits typically run somewhere in the $10 to $25 range for a mixed set of 15 to 30 pieces, and that is the tier most occasional users buy. Step up to a name-brand set with a proper case and better steel, and you are usually looking at roughly $25 to $50. Cobalt or specialty sets climb past that, often $40 to $90 depending on size count and coating.
The purchase price is not the whole story, though. Drill bits are one of the few home items where the running cost is genuinely near zero. There is no electricity bill tied to the bit itself, no filter to replace, no cartridge to swap. The drill does the consuming of power, and a corded drill typically draws a few hundred watts, so drilling 20 holes a year adds up to pennies on your electric bill.
The real consumable cost is replacement. A cheap set dulls faster, and a dull bit does two expensive things: it takes longer, and it can burn or splinter the wood, which means a second trip to the hardware store and a second piece of material. Owner reviews of budget HSS sets often mention bits going soft after a dozen or so holes in hardwood, while reviews of better sets more commonly describe them lasting through a whole project or several. If you replace a $15 set once a year, your first-year cost is about $15 to $30. If a $40 set lasts three years, your annual cost is closer to $13. That is the entire argument in two numbers.
There is also a time cost, and this is where the cleaning and upkeep angle matters more than people expect. Drill bits do not need washing, but they do need handling. Wood chips and sawdust pack into the flutes, and if you leave them there, the next hole runs hotter and slower. A quick wipe with a dry cloth after each use — call it 20 to 30 seconds per bit — keeps them cutting. Do that for 20 bits and you have spent about 10 minutes a year. That is nothing.
What quietly eats time is the mess around the drilling, not the bits themselves. Sawdust on the counter, chips on the floor, a fine dust film on the kitchen table if you drilled indoors. If you are already wiping surfaces, a stack of reusable cloths handles it in one pass. Something like Amazon Basics Microfiber Cloths is the kind of item that turns a two-minute cleanup into a thirty-second one, and the same cloths handle kitchen counters, so you are not buying a single-purpose product. For heavier dust, HOMEXCEL 12-Pack works the same way.
Add it up honestly. Atypical first year for an occasional user: $15 to $50 for bits, under $1 in electricity, and roughly 10 to 15 minutes of total wiping and cleanup across the year. That is the whole bill.
What you get for that money
You get the ability to do a job yourself instead of paying someone. A handyman call for hanging a shelf or mounting a TV bracket usually starts around $75 to $125 in most US markets, and that is before materials. Drill bits pay for themselves the first time you avoid that call, which is the strongest case for owning them.
You also get range. A mixed set covers wood, metal, and plastic in common sizes, usually 1/16 inch up through 3/8 inch, with a few masonry bits thrown in on larger kits. That covers curtain rods, cabinet hardware, furniture assembly, and picture hanging. If you are hanging anything on drywall, the bits are only half the job — you still need anchors, and a kit like OOK Brand 50 lb. Picture Hanging Kit bundles the hooks and hardware so you are not guessing at weight ratings in the aisle.
The other thing you get is speed. A sharp bit in the right material cuts in seconds. A dull bit in the wrong material can take a minute or more per hole and leave a ragged edge you then have to sand or patch. Over a year of small projects, that difference is maybe 20 to 40 minutes total — not life-changing, but real, and it is the difference between a job feeling easy and feeling like a chore.
For anyone doing more than occasional work, the jump in quality is noticeable. Sets like the Bosch Daredevil Set and the DEWALT Black Oxide Set come up repeatedly in owner reviews as holding an edge longer than bargain-bin sets, and the IRWIN Cobalt Set is the tier people move to when they are drilling metal rather than wood. None of that is necessary for hanging two pictures a year.
When it is NOT worth it
Be honest with yourself here, because this is where most budget households waste money.
Do not buy a large set if you drill fewer than about five holes a year. A single 1/8 inch bit and a single 3/16 inch bit, bought individually for a few dollars each, will cover almost everything a renter needs. A 30-piece case just means 28 bits you will never touch and will eventually lose.
Do not buy cobalt or specialty bits for wood. Cobalt is for hard metal and stainless. Using it on pine is paying a premium for a property you will never use. The Neiko HSS Set is a more sensible tier for general household work, and it costs a fraction of what cobalt runs.
Do not buy a set to solve a one-time job. If you are assembling one bookshelf this weekend, borrow a bit or buy the two sizes you need. The set is not the savings; skipping the set is.
And do not buy bits expecting them to last forever. They are consumables. If you are drilling into concrete or hard metal regularly, you will replace them, and that ongoing cost should be part of your decision, not a surprise later.
The cheaper alternative
If you want the smallest sensible spend, skip the big case and buy individual bits in the two or three sizes you actually use. That usually costs under $10 total and covers the vast majority of household jobs.
If you do want a set but want to keep it lean, a smaller HSS set in the 10 to 20 piece range is the sweet spot — enough sizes for furniture, shelves, and basic metal work, without paying for bits that sit untouched. The Neiko HSS Set is a reasonable example of that middle tier, and pairing it with something like DEWALT 27-Piece Hex Key Set covers the assembly jobs that actually come up most often in a household.
Keep your cleanup simple too. A dry cloth wipe after each use, stored with your drill, is genuinely all the maintenance these need. No oil, no soaking, no special cleaner. If you want one cloth that earns its keep across the whole kitchen and the toolbox, E-Cloth General Purpose Pack is a reusable option that survives repeated washing.
The bottom line
Yes, drill bits are worth it — but only if you will use them more than about five times a year and you buy the tier that matches your material, not the biggest case on the shelf. For a strict monthly budget, the smart move is a small HSS set in the $10 to $25 range, individual bits if you drill rarely, and cobalt only if you genuinely work with metal. The running cost is close to zero and the upkeep is about 10 minutes a year. The thing that makes them a waste is not the price. It is buying more bit than your projects will ever need.
Frequently Asked Questions
How often do I actually need to clean drill bits?
Roughly 20 to 30 seconds of wiping with a dry cloth after each use, which adds up to about 10 to 15 minutes across a typical year for an occasional user. Sawdust packed into the flutes makes the next hole run hotter and slower, so the quick wipe is the whole maintenance routine.
Is a cheap drill bit set good enough for hanging shelves and assembling furniture?
For wood, plastic, and light household jobs, a budget high-speed steel set in the $10 to $25 range usually covers it, as long as you are drilling more than a handful of holes a year. If you drill fewer than about five holes annually, buying two individual bits is the cheaper and smarter choice.
Do I need cobalt bits for home use?
Only if you are regularly drilling hard metal or stainless steel. For wood and general household work, a standard high-speed steel set handles the job at a fraction of the cost, and cobalt is paying a premium for a property most homes never use.
