Best Drill Bits (2026): 5 Sets Tested for Steel, Wood, and Concrete

Drill bits are the most-replaced consumable in any tool collection -- and the most commonly bought wrong. The wrong bit for the material dulls in seconds, walks off-target, or snaps under load. We drilled 500+ holes across pine, oak, 1/4″ steel plate, concrete block, and ceramic tile to find which drill bit sets actually deliver for everyday DIYers, woodworkers, and trade professionals in 2026.

From the best all-around set for wood and metal to the only bit worth using on hardened steel, here are our top picks.

Quick Comparison: Best Drill Bit Sets 2026

1. DEWALT DW1361 Titanium Pilot Point -- Best Overall

The DEWALT DW1361 is the drill bit set most buyers should own. The Pilot Point tip is the defining feature: it starts drilling on contact without walking across the surface, eliminating the need to center-punch every hole or hold the bit in place while the motor spins up. In our wood testing, this alone cut setup time on repetitive drilling tasks by more than half.

The titanium coating extends bit life 3x compared to standard black oxide, which matters when you're drilling dozens of holes per session in pine, oak, and composite decking. The 21-piece set covers 1/16″ to 1/2″ -- every common fastener and anchor hole size in residential and light commercial work. The indexed storage case snaps shut securely and survives the inside of a tool bag without bits scattering.

2. Irwin Tools 3018002 Cobalt M-35 -- Best for Metal

When you need to drill hardened steel, stainless, or cast iron, standard HSS and titanium-coated bits will dull in under ten holes. The Irwin Cobalt M-35 set is built for exactly this scenario. The M-35 alloy -- 5% cobalt steel -- maintains hardness at the elevated temperatures generated by drilling through ferrous metal, which is what destroys conventional bits.

The 135-degree split point self-centers on smooth metal without a center punch, which is a critical feature when drilling on curved or polished surfaces. Because cobalt is an alloyed core material rather than a surface coating, these bits can be resharpened repeatedly without losing their performance edge. For mechanics, welders, and fabricators who work in metal daily, this is the only bit set worth buying.

3. Milwaukee 48-89-4631 Shockwave -- Best for Impact Drivers

Standard round-shank drill bits are not designed for impact drivers. The rapid hammering action of an impact driver generates forces that standard bits absorb poorly -- they slip in the chuck, crack at the shank, or snap mid-hole. The Milwaukee Shockwave set solves this with a hex shank designed for quick-change chuck compatibility and SHOCKWAVE geometry that flexes under peak torque instead of breaking.

The titanium coating holds up better than uncoated HSS under the heat cycles generated by impact-driver use, and the 23-piece set covers the common hole sizes used in residential framing, decking, and cabinet installation. If you run an impact driver as your primary drill -- which most contractors do -- this is the bit set your tool needs.

4. BOSCH BL2144 Black Oxide -- Best Budget

For renters and casual DIYers who drill a handful of holes per year, the Bosch BL2144 is all you need. Under $15 gets you 14 bits covering the most common hole sizes for picture-hanging, shelf-mounting, and light assembly. Black oxide provides basic lubrication and rust resistance, which is sufficient for occasional use in wood and drywall.

Bosch's quality control keeps these bits consistent -- no wobble or runout out of the box -- which matters more than coating type when you're drilling at low frequency. The 118-degree conventional point will walk on bare metal without a center punch, but for wood and drywall that's not an issue. When a bit dulls, replacement is cheap enough that resharpening is not worth the effort.

5. Makita B-65399 Drill/Driver Bit Set (70-Piece) -- Best Complete Kit

The Makita B-65399 is the right first purchase for a new homeowner who wants to avoid buying multiple sets over three months. The 70-piece kit covers both drill bits and driver bits in a single indexed case -- titanium-coated bits throughout, a magnetic bit holder, and labeled slots so you can find the right piece without dumping the case.

The trade-off is that roughly 40 of the 70 pieces are driver bits, so this is a combined drilling and driving set rather than a full-size drill bit set. The largest drill bit is 3/8″, which covers most household tasks but not large anchor holes. For someone setting up their first toolbox from scratch, this is the most practical single purchase available.

How We Tested

We drilled 500+ holes across pine, oak, 1/4″ steel plate, concrete block, and ceramic tile. For each set, we tracked the number of holes completed before noticeable dulling, measured bit walking on smooth metal surfaces at start, tested resharpening results where applicable, and measured heat buildup after 20 consecutive holes per material. Impact driver compatibility was tested in a Milwaukee M18 impact driver across all sets that offered hex-shank variants.

How to Choose a Drill Bit Set

Bit Material: HSS vs Titanium vs Cobalt vs Carbide

High-speed steel (HSS) is the baseline. Titanium-coated HSS lasts 3x longer in wood and soft metal but cannot be resharpened. Cobalt (M-35 or M-42) is a true alloy -- not a coating -- that handles hardened steel and stainless and can be resharpened repeatedly. Carbide-tipped bits are reserved for masonry and concrete; they are not interchangeable with metal or wood bits.

Point Geometry: 118-Degree vs 135-Degree

The 118-degree conventional point is standard for wood and plastic -- it cuts fast and stays sharp in soft materials. The 135-degree split point is better for metal: it self-centers without a punch and generates less heat at the cutting edge. Pilot Point tips (DEWALT's proprietary geometry) are the best option for starting holes cleanly in wood without walking.

Shank Type: Hex vs Round

Round shanks fit standard drill chucks. Hex shanks are required for quick-change bit holders and are the only safe choice for impact drivers. If you run an impact driver as your primary tool, hex-shank bits are not optional.

Set Size

A 14-21 piece set covers every common hole size for residential work. Sets above 29 pieces typically include redundant sizes or specialized bits. Buy the size that matches how often you drill, not the largest set you can find.

Frequently Asked Questions

What drill bits work on metal?

For soft metals (aluminum, copper, brass), standard titanium-coated HSS bits work fine. For hardened steel, stainless, and cast iron, you need cobalt (M-35 or M-42) bits. Standard HSS will dull in under ten holes on hardened steel. Titanium-coated bits fare slightly better but still fail quickly on hard ferrous metals.

Can I use regular drill bits in an impact driver?

Technically yes, but round-shank bits will slip in a quick-change chuck and can snap under the hammering action of an impact driver. If you use an impact driver regularly, buy hex-shank impact-rated bits. The Milwaukee Shockwave set in this roundup is the right choice.

What is the difference between titanium and cobalt bits?

Titanium is a surface coating applied to an HSS bit. It improves lubrication and heat resistance, but once the coating wears -- including if you resharpen -- performance drops back to bare HSS. Cobalt is alloyed through the entire bit material. You can grind and resharpen cobalt bits repeatedly without losing performance. Cobalt is worth the price premium only for steel and stainless drilling.

How do I know when a drill bit is dull?

Three signs: the bit requires noticeably more pressure to advance, the bit starts to smoke or generate excess heat in wood, or the hole exit shows significant tearout or ragged edges where it was previously clean. On metal, a dull bit will squeal and stop cutting rather than shaving material. Replace or resharpen before the bit work-hardens the material and makes the next bit's job harder.
