Masonry Drill Bits
Masonry drill bits are what you reach for when timber bits just burn out and spin. Built for brick, block, concrete and stone, they cut properly into hard materials.
If you're fixing battens to block, hanging trunking on brick, or drilling anchors into concrete, the right masonry drill bits save time and stop you wrecking bits. Standard masonry drill bits suit general hammer drilling, while SDS masonry drill bits are for tougher concrete and repeated site work. Check shank type, length and tip design properly, then pick the bits that match the wall in front of you.
What Are Masonry Drill Bits Used For?
- Drilling fixing holes into brick and block is the everyday job for masonry drill bits, whether you are fitting cable clips, mounting conduit, or putting up timber battens on first fix.
- Breaking into harder concrete for anchor bolts, frame fixings, and bracket work is where concrete drill bits and SDS masonry drill bits earn their keep on heavier site jobs.
- Working through stone, dense block, and older hard-fired brick calls for carbide tipped masonry drill bits that keep cutting instead of just polishing the face of the hole.
- Using masonry bits for cordless drills is common for snagging, maintenance, and short fixing runs where you need fast holes without dragging a bigger corded combi round site.
- Reaching through deep reveals, insulated walls, or thick masonry is where long masonry drill bits make sense, especially when standard lengths will not get you through in one pass.
Who Uses These on Site?
- Sparkies use brick drill bits and hammer drill bits for brick every day for clips, tray, back boxes, and surface fixings, usually keeping a few common sizes in the case so they are not caught short mid run.
- Plumbers and heating engineers rely on masonry drill bits for pipe clips, bracket fixing, and running services through block and brick, especially on refurb jobs where wall density changes room to room.
- Joiners and kitchen fitters use concrete drill bits and standard masonry drill bits for frame fixings, cabinet rails, and timber-to-masonry work where a clean, accurate hole matters.
- General builders, dryliners, and maintenance teams reach for SDS masonry drill bits when they are drilling repeatedly into tougher concrete, dense lintels, or older site walls that chew through lighter bits.
- Groundworkers and installers use long masonry drill bits for deeper penetrations through thicker walls, external masonry, and awkward access points where a stubby bit just will not reach.
Choosing the Right Masonry Drill Bits
Sorting the right masonry drill bits is simple: match the bit to the wall and the drill, not whatever happens to be nearest in the van.
1. Standard Shank or SDS
If you are drilling light to medium fixing holes in brick and block with a combi drill, standard masonry drill bits are usually enough. If you are into concrete all day or drilling larger holes repeatedly, go straight to SDS masonry drill bits and a proper rotary hammer.
2. Brick, Block, Concrete or Stone
For ordinary facing brick and block, most carbide tipped masonry drill bits will do the job well. If the wall is dense concrete, engineering brick, or stone, buy for the harder material from the start or you will blunt cheap bits fast and waste half the morning.
3. Bit Length Matters
Do not buy long masonry drill bits unless the job genuinely needs the reach, because extra length can wander more in the hole. For plugs and day to day fixings, a standard length gives you better control. For deep penetrations, cavity work, and thick walls, the longer bit is the right call.
4. Buy the Sizes You Actually Use
Most trades burn through the same few sizes, so stock those first. If you are mainly fixing clips, brackets, and plugs, focus on the common diameters for wall plugs and light anchors rather than filling the box with sizes you will barely touch.
The Basics: Understanding Masonry Drill Bits
Masonry drill bits work by crushing and cutting hard material with a tougher tip than a normal wood or metal bit. The bit type and drill action make a big difference to how fast the hole goes in and how long the bit lasts.
1. Carbide Tipped Cutting Edge
Most masonry bits use a carbide tip to deal with brick, block, concrete, and stone. That hard tip does the real work at the face of the hole, so once it overheats or chips, progress drops off quickly and the bit starts skating instead of cutting.
2. Hammer Action vs Rotary Hammer
Standard masonry bits usually run in a hammer drill or combi drill, which is fine for general brick and block. SDS masonry drill bits are made for rotary hammers, where the stronger hammer mechanism makes drilling into concrete much quicker and far less of a fight.
3. Flute Design Clears the Dust
The spiral flutes pull dust out of the hole as you drill. If dust is not clearing, the bit heats up, slows down, and binds. That is why the right speed, steady pressure, and pulling the bit out now and then all help on deeper holes.
Masonry Bit Accessories That Save Time on Site
A few add-ons make masonry drilling cleaner, quicker, and a lot less frustrating when the wall fights back.
1. Depth Stops
This stops you going too deep when you are drilling for plugs and repeated fixings. Handy on first fix and kitchen work where every hole wants to be consistent and you do not want fasteners disappearing into oversized holes.
2. Dust Extraction Adaptors
Get one if you are drilling indoors on finished jobs or occupied buildings. It cuts down the mess at source and saves you from trailing dust through the client area or spending longer cleaning than drilling.
3. Bit Cases and Organisers
Loose masonry drill bits rolling round the van get damaged, mixed up, and go missing. A proper organiser keeps the common sizes together so you are not hunting for a 6mm bit every time you need to put a plug in a wall.
4. Spare Common Sizes
There is always one size that gets hammered all week. Keeping spare 5mm, 6mm, 7mm, or 8mm bits in the box means a worn tip does not stop the job or send someone back to the merchant for one cheap consumable.
Choose the Right Masonry Drill Bits for the Job
Use this quick guide to match the bit to the wall, drill, and fixing job.
| Your Job | Masonry Drill Bit Type | Key Features |
|---|---|---|
| Fixing clips, brackets, or battens into brick | Standard masonry drill bits | Round shank, carbide tip, works in a combi drill with hammer mode for everyday site fixings |
| Drilling repeated holes into concrete lintels or slabs | SDS masonry drill bits | SDS shank, faster dust clearance, better for rotary hammers and tougher concrete work |
| Snagging jobs with a cordless combi | Masonry bits for cordless drills | Lighter duty sizes, quick setup, suited to short runs in brick and block without dragging bigger kit round |
| Going through thick walls or deep reveals | Long masonry drill bits | Extra reach for deeper holes, cavity work, and awkward access where standard bits fall short |
| Drilling dense stone or very hard block | Carbide tipped masonry drill bits | Tougher cutting edge, better wear resistance, and less chance of the bit giving up early in hard material |
Common Buying and Usage Mistakes
- Using a standard drill bit instead of a masonry drill bit is the quickest way to burn the tip, glaze the hole, and get nowhere. If the wall is brick, block, concrete, or stone, use the proper carbide tipped bit from the start.
- Buying SDS masonry drill bits for a normal chuck catches people out all the time. SDS bits need an SDS rotary hammer, while standard masonry drill bits are for combi drills and conventional chucks.
- Pushing too hard and drilling too fast overheats the tip and blunts the bit early. Let the hammer action do the work, back the bit out to clear dust, and do not lean on it like you are boring timber.
- Picking the wrong diameter for the fixing leaves plugs loose or cracks the surrounding material. Check the wall plug or anchor size before you drill, not after the hole is already in.
- Trying to use one bit for brick, reinforced concrete, tile, and stone without changing approach wastes time. Match the bit and drill mode to the surface or you will damage the material and shorten bit life.
Standard Masonry Drill Bits vs SDS Masonry Drill Bits vs Long Masonry Drill Bits
Standard Masonry Drill Bits
These are the everyday choice for brick, block, and lighter concrete work in a combi drill. They are the sensible option for plugs, brackets, and general fixing work, but they are slower and harder going once you hit dense concrete all day.
SDS Masonry Drill Bits
These are for rotary hammers and tougher work. If you are drilling into concrete regularly, larger diameters, or repeated holes on site, SDS masonry drill bits are quicker, track better, and put less strain on you and the drill.
Long Masonry Drill Bits
These come into their own on thicker walls, deep penetrations, and awkward access. They are not automatically better for normal plug holes, because the extra length can wander more, so buy them for reach rather than as a default.
Maintenance and Care
Clear Dust After Use
Brush or wipe the dust off after drilling, especially around the flutes and tip. Packed-on masonry dust holds moisture and grime, which is not great for storage or accurate drilling next time out.
Check the Tip Before the Next Job
If the carbide tip is chipped, rounded, or looks polished over, retire it from precision work. A tired bit still spins, but it drills slowly, wanders more, and leaves poor holes for plugs and anchors.
Store by Size, Not Loose
Keep bits in a case or organiser instead of rolling round the van. It stops the tips knocking together, makes worn sizes easier to spot, and saves time when you need a specific diameter quickly.
Replace Worn Common Sizes Early
Do not hang on to a blunt 6mm bit just because it still technically drills. If it takes twice as long and leaves oversized holes, it is already costing you more in time and fixings than a replacement bit.
Use the Right Drill Mode
A lot of bit wear comes from misuse rather than poor quality. Run standard masonry bits in hammer mode where suitable, use SDS bits in the correct tool, and avoid hammer action on surfaces that need a gentler start.

Masonry Drill Bits FAQs
Can I use masonry bits in a cordless drill?
Yes, provided the drill has a hammer mode and you are working in brick or block rather than very hard concrete. Masonry bits for cordless drills are fine for general fixings and snagging jobs, but if you are drilling lots of holes or hitting dense concrete, an SDS setup is the better tool.
What size masonry bit do I need for wall plugs?
Match the bit to the plug size exactly. A 6mm wall plug usually wants a 6mm masonry drill bit, and the same rule applies up the range. If the bit is worn and drilling oversize, the plug will spin or pull loose, so check the bit condition as well as the marked size.
Do I need SDS masonry drill bits for drilling into brick or concrete?
Not always. For normal brick and block, standard masonry drill bits in a decent combi drill usually do the job. For concrete, repeated drilling, larger diameters, or harder site work, SDS masonry drill bits are well worth it because they cut faster and put less strain on the tool.
What is the difference between masonry drill bits and standard drill bits?
Masonry drill bits have a carbide tip designed to break down hard materials like brick, block, concrete, and stone. Standard drill bits for wood or metal are shaped for cutting softer or more uniform material, so in masonry they overheat, skid about, and wear out quickly.
Can masonry drill bits be used on stone and block?
Yes, many masonry bits for stone and block are built exactly for that. The catch is density. Soft block drills easily, while dense stone can be slow going and hard on the tip, so a sharper carbide tipped masonry drill bit and the right drill make a big difference.
Why do masonry drill bits go blunt quickly?
Usually it is heat, too much pressure, the wrong drill mode, or trying to force a light bit through material that is too hard for it. Cheap bits wear sooner as well, but even good ones die early if dust is not clearing and the tip is getting cooked in the hole.
What type of masonry drill bit is best for brick?
For ordinary facing brick and general fixing work, standard masonry drill bits with a carbide tip are the usual choice. If the brick is very hard, old, or you are drilling a lot of holes, a better quality hammer drill bit for brick will stay sharp longer and track more cleanly.
Can I use a masonry drill bit on tiles?
Not as a first choice. A masonry drill bit can crack or skate across glazed tile if you go straight in with hammer action. Start with a proper tile bit or glass and tile bit, then switch to masonry once you are through the surface and into the wall behind.
