Best Drill Bit Set (2026): 5 Sets Compared

Compared on paper

Specifications are manufacturer rated, as published on each listing and collected 3 November 2026. Where a listing contradicts itself, both figures are shown.

How the points were given

Each set is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. None states a safety certification or a warranty term, so safety points come only from stated anti-walk and anti-spin-out features, and no warranty points are given.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

What the listings tell you

We read 5 drill bit listings. All 5 state a piece count and a split point, and 4 of the 5 give that point as 135 degrees. None states a warranty term, and none states a safety certification. Two listings contradict themselves: one on the carrying case material and one on stainless steel.

Buying guide: best drill bit set

Size range and piece count

Piece count only matters against the sizes you drill. The sets here run 14 pieces, 21 pieces, 29 pieces and 115 pieces, and the largest set covers three sizing systems: 29 fractional bits from 1/16 to 1/2 inch, 26 letter bits from A to Z, and 60 numbered bits from #1 to #60. A 14-piece set covers the common household sizes, while the 115-piece set covers odd sizes a repair job sometimes calls for.

Point, helix and shank

The point decides whether the bit starts where you aim. Four of the sets state a 135 degree split point that reduces walking, and the fifth states a split point with no degree given. The DEWALT 21-piece set adds a 31 degree helix and parabolic flutes for chip ejection in metal and wood, and the DEWALT 14-piece set adds a 3-flats shank that reduces spin-out in the chuck on sizes larger than 3/16-in.

Material match

Match the bit material to the work, not the other way around. High speed steel covers wood, plastic and general metal work across these listings, while the M35 cobalt set is the one that states hardened steel and stainless steel among its materials. The CaRoller listing contradicts itself on stainless steel, stating it among the materials in one bullet and advising against it in its note, so check the note before buying that set for stainless work. Clamp the work, keep hands clear of the bit, and wear eye protection.

Cases and storage

A set that lives loose in a drawer loses bits. The MACXCOIP set comes in an index storage case, the CaRoller set in a metal indexed case, and the CRAFTSMAN set in a carrying case whose material the listing gives as both metal and plastic. The two DEWALT sets state no case, so plan a separate place to keep those bits sorted.

Garage Fit Check

• Storage: the MACXCOIP set comes in an index storage case, and the CaRoller set in a metal indexed case, so bits stay sorted.
• Space: the MACXCOIP case measures 15.35 x 6.3 x 4.33 inches, so leave drawer or shelf room for it.
• Power: these are bits only, not drills; they need a drill to drive them.
• Fit check: match the shank and bit size to the drill and the job before buying.
• Check before the first job: confirm the case material and the stainless rating on the listing, since two listings contradict themselves.

FAQ: garage tools

How do I choose a drill bit size?

Match the bit to the hole the job needs, not to the largest bit in the set. The sets here cover 1/16 to 1/2 inch in their fractional ranges, so a small pilot hole and a larger clearance hole both sit inside one set.

How do I change a drill bit?

Loosen the chuck, remove the old bit, seat the new bit straight, and tighten the chuck before drilling. A 3-flats shank, as on the DEWALT 14-piece set, reduces spin-out in the chuck on sizes larger than 3/16-in.

What is a drill bit set?

A drill bit set is a collection of bits in a range of sizes, sold together in a case or pack. The sets here run 14 pieces, 21 pieces, 29 pieces and 115 pieces, from common household sizes to fractional, letter and numbered sizes.

What do fractional, letter and numbered sizes mean?

They are three sizing systems for drill bits. The MACXCOIP set covers all three: 29 fractional bits from 1/16 to 1/2 inch, 26 letter bits from A to Z, and 60 numbered bits from #1 to #60.

Which set covers stainless steel?

The MACXCOIP M35 cobalt set states stainless steel among its materials, along with hardened steel and cast iron. The CaRoller set lists stainless steel in one bullet but advises against it in its note, so follow the note for stainless work.
