Best Concrete Drill Bits 2026: Top Carbide & SDS Picks for Every Job
Quick answer: Start with the drill, not the bit. If you own a rotary hammer, you need SDS-Plus and a set is cheaper than buying sizes one at a time. If you own a drill or hammer drill, you need a round shank, and the seven-piece DeWalt set is the most-bought bit on this page by a wide margin. Only worry about four-cutter geometry if you expect to hit rebar.
| What you own | Buy this | Why |
|---|---|---|
| Rotary hammer, general work | Bosch HCK001 set | Seven SDS-Plus sizes, 4.8 stars across 1,508 ratings, sold by Amazon |
| Rotary hammer, hitting rebar | Bosch HCFC2064 | Four-cutter full head — Bosch claim up to 4x life in concrete with rebar |
| Drill or hammer drill | DeWalt DW5207 set | 8,670 ratings, seven round-shank sizes, cheapest per bit here |
| Drill, one deep hole | Bosch LBH009 | 3/8" x 12", asymmetric tip that resists walking on the start |
Cutter geometry, RPM by diameter and wet-vs-dry coring are covered in the full Masonry Drill Bits guide. If you are still deciding whether the two categories differ at all, start with masonry vs concrete bits.

Author: Thomas Leroy, Construction & Renovation Specialist
Fifteen years of hands-on residential construction and renovation, using most of the power tools on the market across a wide range of brands. Concrete bits are the one accessory where the expensive mistake is not buying cheap — it is buying a shank that physically cannot fit the drill you already own. Every figure below comes from the manufacturer’s own specification or the live listing, and where a listing contradicts itself, this page says which part is right.
How a Masonry Bit Actually Works
A masonry bit does not cut concrete. It crushes it. The carbide tip is driven into the aggregate by the hammer action of the drill, shattering it a fraction of a millimetre at a time, while the spiral flutes carry the dust back out. A twist bit shears material away with a sharp edge; a masonry bit has no sharp edge to speak of, and does not need one.
That explains the failure everyone hits once — a masonry bit in a rotary-only drill has nothing to crush with, so it polishes the hole and cooks the carbide instead. It also explains why cutter count only becomes an argument at rebar, where extra edges share an impact that would chip a two-cutter tip.
Before any of that, one question decides the purchase entirely, and it has nothing to do with quality: which shank does your drill take?
SDS-Plus Picks (Rotary Hammers)
All four SDS-Plus picks below fit any standard SDS-Plus rotary hammer regardless of brand — the shank system is universal even though the tool brands aren't.
Also real, but not featured here
These three are genuine products and they work. They are not given a full write-up above for one reason each — stated plainly, because "we did not pick it" is more useful than silence.
| Bit | Size | Cutter | Rating | Why it is not a pick here |
|---|---|---|---|---|
| Milwaukee MX4 | 1/2" x 4" x 6" | 4-cutter | 4.8 · 40 reviews | only 40 ratings; third-party seller; listing has 14 size variants and the feature text is boilerplate |
| Hilti TE-CX | 1/2" x 6" | 4-cutter, X-tip | 4.5 · 21 reviews | only 21 ratings; third-party seller; premium price needs more proof than that to recommend |
| DeWalt DW5529 | 3/8" x 8" x 10" | 4-cutter | 4.4 · 9 reviews | 9 ratings is not enough to feature; third-party seller with 13 units left |
Review counts checked against the live listings. A bit with nine ratings is not a bad bit — it is an unproven one, and at these prices there are better-evidenced options above.
Round Shank Pick (Standard Drill)
If your drill has a standard keyed or keyless chuck rather than an SDS-Plus one, you need a round or grip shank — a genuinely different product, not the same bit under another name. Both picks below fit any drill or hammer drill.

What Independent Testing Found
Bob Vila ran real hands-on testing across concrete, stone, and brick, using a standard DeWalt drill and a Milwaukee rotary hammer depending on each bit's shank type, drilling dozens of holes across all three materials and scoring performance against a rubric to produce both an overall pick and category-specific picks. This is genuine, methodology-disclosed testing, not a marketing rubric — worth weighing alongside the manufacturer specs above rather than relying on spec sheets alone.
Testing methodology per Bob Vila's published concrete drill bit testing.
What to Look For in a Concrete Drill Bit
Three things actually matter, in order: shank type first, since an SDS-Plus bit physically will not fit a standard drill chuck and vice versa; carbide construction second, where full-carbide tips generally outlast brazed carbide-tipped bits, especially with repeated use; and cutter count third, which genuinely matters more above 1/2" diameter and with regular rebar contact, and matters much less below that. For the full technical explanation of cutter geometry, RPM speeds, and wet vs. dry coring, see our complete Masonry Drill Bits guide.
Common Mistakes
Frequently Asked Questions
What's the best concrete drill bit overall?
Bosch's HCK001 Bulldog set is the strongest default pick for general concrete, brick, and block work at typical anchor-installation diameters. For regular rebar contact, Milwaukee's MX4 4-cutter design is the better choice.
Will an SDS-Plus bit fit my regular drill?
No. SDS-Plus bits have a splined shank that only fits SDS-Plus rotary hammer chucks. A standard drill needs a round or grip-shank bit instead — these are physically different shank systems and not interchangeable.
Is a more expensive concrete drill bit actually better?
Often, but not automatically. Hilti's TE-CX carries a real price premium and is genuinely justified for high-volume professional use where bit replacement frequency is a real cost. For occasional homeowner use, Bosch's HCK001 or DeWalt's DW5207 perform well at a lower price point.
Do I need a 4-cutter bit for concrete drilling?
Only really matters above 1/2" diameter or with regular rebar contact. Below that, a well-made 2-cutter bit performs comparably, often for less money. See our full Masonry Drill Bits guide for the complete technical explanation.
What size drill bit do I use for a concrete anchor?
For wedge, sleeve and most expansion anchors the bit diameter matches the anchor diameter — a 3/8" wedge anchor takes a 3/8" bit. Drop-in anchors are the exception and catch people out: a 3/8" drop-in needs a 1/2" bit, because the size refers to the internal thread rather than the hole. Concrete screws are different again — a 3/16" Tapcon takes a 5/32" bit.
Can I use a concrete bit in a regular drill?
A round or grip-shank masonry bit will physically fit any standard chuck, but without hammer action it will not cut concrete meaningfully — it polishes the hole and cooks the carbide. A hammer drill in percussion mode handles small diameters fine. Above roughly 3/8" in poured concrete you want a rotary hammer and SDS-Plus bits.
How long should a concrete drill bit last?
There is no honest single number — it depends on concrete strength, aggregate hardness, whether you hit rebar, and how hot the bit gets. What is measurable is the failure mode: a bit that stops cutting and starts smoking is usually glazed carbide from heat, not a worn edge. Back off pressure, let it clear dust, and it will last several times longer.
