The 10 Best Drill Bit Sets
Twist drill bit sets for wood, plastic and metal, ranked from live Amazon data.
Ranked by ToolboxTop10 from Amazon data captured Nov 9, 2026. How we rank
A good drill bit set matters more than most people think: a dull or wandering bit makes a $200 drill drill badly. We ranked 10 best-selling sets from DEWALT, Makita, Bosch, CRAFTSMAN and value brands on rating, review volume and features: a self-centering split or pilot point, sizes up to 1/2 inch, a shank that won't spin in the chuck, and a case or index to keep the sizes in order. Prices run from $9.98 for CRAFTSMAN's 14-piece set to $129.98 for a 115-piece cobalt index.

How we rank
Every tool gets one score from 0 to 100, weighted
45% on its star rating,
35% on how many people have reviewed it (more reviews = more
confidence the rating is real), and 20% on the features that
matter for the job. The list is ordered by that score. Best Overall is our pick for the
best all-around, ready-to-use tool; Best Budget the best value at or under
$15; and Money No Object the one to buy if price is no object.
The features score is built from self centering (30%), wide range (25%), a carrying case (25%), anti spin (20%), capped at 100. The review-count score is on a log scale, so each tenfold jump in reviews adds the same amount, and 30,000 or more reviews gets full marks. Open Why this score on any tool to see its numbers.
Buyer's guide
HSS, titanium or cobalt: which do I need?
High-speed steel (HSS) handles wood, plastic and mild steel, and it's what most sets are. Titanium nitride (TiN) is a coating on HSS that cuts friction and adds life until it wears off. Cobalt (M35 or M42) is an alloy all the way through, so it keeps its edge in stainless steel and cast iron and can be resharpened. Buy cobalt only if you drill hard metal.
What does a split point do?
A 135-degree split point has a second cut at the tip so the bit starts cutting on contact instead of skating across the surface. That means you rarely need a center punch. DEWALT's Pilot Point does the same job.
Round, 3-flat or hex shank?
Round shanks can spin in a keyed or keyless chuck under load. Three flats give the chuck jaws something to grip. A 1/4 inch hex shank snaps into quick-change chucks and impact drivers, but only buy hex bits rated for impact use if you'll use them in an impact driver.
What sizes should a starter set have?
1/16 to 1/2 inch covers pilot holes for screws up to lag bolts and most anchor holes. Look for spares of the small sizes (1/16 to 1/8 inch), because those snap first.
Can I drill concrete or brick with these?
Not with twist bits. Masonry needs carbide-tipped masonry bits, ideally in a hammer drill. Of the sets here, the Amazon Basics and COMOWARE 246-piece kits include masonry bits.
Is a 100-plus piece kit better than a 21-piece set?
Only if you'll use the extras. Big kits pad the count with screwdriver bits and nut drivers. If you already own driver bits, a focused 21-piece twist set like the DEWALT DW1361 gets you better bits for the money.
