Masonry Drill Bit vs Concrete Drill Bit: What Is the Difference?

Why the two names overlap

Most stores and makers use "masonry" and "concrete" loosely. A set labeled as a concrete drill bit may be sold for brick, block and stone too. A set labeled masonry may list concrete in its materials.

What matters is how the bit is built and which drill it is meant for. Both kinds break material apart with a hard tip rather than cutting fibers the way a wood bit does. Both use a carbide tip brazed onto a steel body, and both rely on flutes to carry dust out of the hole.

So think of it as a spectrum. Lighter bits for chuck drills sit at one end. Heavier, impact-rated bits for hammering sit at the other, and those are the ones people most often call concrete bits.

What a masonry drill bit looks like

A typical masonry bit has a steel body with spiral or U-shaped flutes and a flat, spear-shaped carbide insert at the tip. The tip is wider than the body, so the bit cuts a hole slightly larger than the shaft and the flutes can clear dust.

The shank is the end that goes into the drill. Standard masonry bits use a round, 3-flat round or hex shank that grips in an ordinary chuck. Our listings show this clearly. The DYRECELVE 12-piece set has a 3-flat shank, carbide tips and spiral flutes, and it is listed as not for SDS rotary hammers. The DKIBBITH set uses a 3-flat shank with tungsten carbide and a U-type slot.

Brick bits are not a separate family. They are ordinary masonry bits used in brick, which is softer than concrete.

Where concrete bits differ

Concrete is harder and often contains aggregate and steel reinforcement, so bits for it tend to be sturdier. The common format is an SDS-Plus shank with grooves that lock into a rotary hammer. The drill can then hammer the bit forward while it turns, which suits repeated impact far better than a chuck.

The WORKPRO 48701 is an example. It lists an SDS-Plus shank, carbide tips, U-shaped flutes and 17 pieces, including chisels and a case. The Bosch HCK001 lists an SDS-Plus shank, tungsten carbide tips and seven bits, aimed at reinforced concrete.

Some concrete bits use a hex shank instead. The Milwaukee 48-20-9051 five-piece set lists a hex shank, carbide edges, a wide flute and hammer drill compatibility. That shows the shank alone does not tell the whole story, so read the maker's notes on drill type.

Side-by-side comparison

This table shows the usual pattern. Individual products vary, so treat it as a starting point.

How to tell which bit you have

If the bit is unmarked or the packaging is gone, check these in order:

• Look at the shank. Two or four slots near the end mean SDS-Plus. A smooth round or three-sided shank means a chuck bit. A six-sided shank is hex.
• Check the tip. A small dark insert of carbide, wider than the body, marks a masonry or concrete bit. Plain steel with a ground point is a metal or wood bit.
• Look at the markings. Many sets print the diameter on the shank, and some name the drill type.
• Read the drill notes. Some listings say not for hammer drills or SDS tools. The TITGGI set is listed as not hammer drill compatible, and the DKIBBITH set says it is not suitable for impact drills.

Matching the bit to your drill and job

Start with your drill. If you own a standard drill driver, pick bits with a round, 3-flat or hex shank made for chuck drills. They suit anchors and small holes in brick, block and light masonry. If you have a rotary hammer, SDS-Plus bits are the natural fit for concrete.

Next, check size and depth. Anchors call for a specific diameter, and deep holes need long bits. Among the models on our best masonry drill bits page that list it, diameters run from 0.125 in to 0.75 in, and the longest listed bit is 6 in. The Bosch set publishes a 0.1875 to 0.5 in range with a 6 in longest bit, while many makers do not publish these numbers.

If you want to compare shanks, tips and flutes across several sets, see our best masonry drill bits comparison. For help choosing the drill itself, see our best drill page. If you also need bits for wood and metal, a drill driver bit set covers those jobs, since masonry bits are only for hard mineral materials.

Safety and technique

Drilling masonry creates fine dust and loud noise, and hammer action adds vibration. A few habits help:

Wear safety glasses and a dust mask rated for fine dust, and use hearing protection with a hammer drill or rotary hammer. Concrete dust can irritate your lungs, so ventilate the area or use dust control.

Before drilling a wall, check for hidden electrical cables and pipes. Use a detector if you are unsure, and keep your hands off any metal parts of the drill near a possible live wire.

Start at low speed with light pressure and keep the drill straight. Let the bit cool between holes, because a clogged hole builds heat. Some makers suggest adding water on hard surfaces, but never use water near live wiring or with a corded tool in a damp area. If you hit rebar, stop and switch to a bit made for it rather than forcing the tip.

Frequently asked questions

Can I use a masonry bit in concrete?

Often yes, for small holes in light concrete with a chuck drill, going slowly and letting the bit cool. For larger or deeper holes, or reinforced concrete, an SDS-Plus bit in a rotary hammer is a better match.

Can I put a masonry bit in a hammer drill?

Only if the maker says so. Some sets are listed as hammer drill compatible, while others say they are for rotary mode only. Check the product notes first.

Are brick bits different from masonry bits?

No. Brick is one of the materials masonry bits are made for, so a standard carbide-tipped masonry bit works in brick.

Can masonry bits drill tile or glass?

Some sets list tile, ceramic or glass among their materials. Use low speed, light pressure and a steady hand, and check the listing first.
