A carbide-tipped masonry bit, low speed, and steady pressure help the bit cut cleanly instead of skidding across the surface. That approach helps you avoid spalling, keep the hole straight, and seat an anchor without chipping the brick face.
This guide covers the practical steps for anyone hanging shelves, brackets, or a TV mount on brick, from selecting the right tool to marking, drilling, and protecting the wall’s surface.
Choosing The Drill And Bit That Match Brick
Tool choice changes the result more than most beginners expect. A small hole in sound masonry can tolerate a standard drill, while harder brick and repeated holes call for more impact and a better bit.
| Job size | Drill choice | Bit choice |
|---|---|---|
| Light hanger, one or two holes | Standard drill can work with patience | Carbide-tipped masonry bit |
| Multiple holes, medium load | Hammer drill for brick | Carbide-tipped masonry bit |
| Deeper holes, dense or aged masonry | Rotary hammer | Matching masonry bit rated for the tool |
| Cable pass-through or larger opening | Hammer drill or rotary hammer | Long masonry bit or core bit as needed |
Ordinary wood or metal bits skid on brick because their edges are made for softer materials. A masonry drill bit has a carbide tip that bites into fired clay and mortar, and that extra hardness matters as soon as the surface starts resisting.
Tool fit matters. A normal drill can handle a small hole in sound brick, but it asks more of your wrist and bit. A hammer drill adds rapid in-and-out motion that helps the bit chip masonry instead of rubbing it, and a rotary hammer goes farther on dense walls, deeper holes, or repeated work.
For a single anchor hole in decent brick, a hand drill can work. For several holes, thicker anchors, or deeper mounting points, the hammer drill saves effort and gives a cleaner cut. A rotary hammer earns its place on harder masonry, long holes, or repeated work where a standard drill starts to stall.
That choice matters because the wall itself decides how much control the bit will need.
Reading The Wall Before You Start
Wall condition shapes the whole job. Solid brick takes fasteners differently than veneer, and damaged mortar can turn a simple mount into a loose one.
Spot Solid Brick Versus Veneer
A thick, stable wall usually indicates solid masonry, while veneer brick covers a framed structure and carries less load. Knock gently and listen: a hollow sound can point to veneer, and that changes how much weight the wall can hold.
Historic brick deserves extra care because older units can be softer, more brittle, or held together with aged mortar. Pine Hall Brick notes that brick face is the safer place for many fasteners, but the wall still needs enough thickness and sound material to hold the anchor.
Choose Safer Zones On The Wall
The center of a full brick face gives you the best chance for a clean hole. Edges, corners, and mortar joints break more easily because the material there has less mass and more internal stress.
- Brick face center: Best for most light and medium anchors.
- Sound mortar joint: Acceptable for very light fixtures in some cases.
- Brick edges: Higher risk of spalling and corner breakage.
- Cracked brick: Poor choice for a new hole and a load-bearing anchor.
- Loose mortar: Can crumble around the bit and widen the hole.
Avoid the temptation to drill into the nearest joint. The joint may look tidy, yet weak mortar can crumble under pressure and leave your anchor loose.
That wall read tells you where to place the hole and where to stay away from. Once the spot is clear, the next job is marking the exact point and depth so the bit starts straight.
With the surface mapped, accuracy depends on getting the starting point and stopping depth right.
Marking The Hole And Setting The Depth
A clean start begins with a visible mark, not guesswork. A dark pencil dot or a small cross of masking tape gives the bit a target and keeps the point from skating across the face.
Set A Stop Before Drilling
Depth control keeps you from drilling too deep and weakening the hold. A drill stop collar works well, and masking tape wrapped around the bit gives you a quick visual limit that you can check in seconds.
Match the hole to the anchor or screw before you pull the trigger. A 1/4 inch anchor needs a 1/4 inch hole, and a larger shield or sleeve needs the matching diameter, not a size guessed from the hardware aisle after dust is already falling.
Mark For The Fastener, Not For The Bit
The mark should match the mounting point, not the tip shape. A shelf bracket with two slots, for example, needs both hole centers measured from the bracket itself so the fasteners line up without forcing the metal sideways.
A tiny offset can matter more on brick than on drywall because masonry does not forgive much wandering. That is why a tape measure, a level, and a sharp mark save more time than trying to correct the position later.
Once the mark and depth are set, the actual drilling goes faster and cleaner. The next section covers the controlled motion that keeps the bit from chattering across the face.
Those reference points set the stage for a steadier cut and less wandering at the brick face.
The Controlled Drill Sequence That Protects Brick
Low speed and steady pressure do the work here. A fast start heats the bit, rounds the mark, and can chip the surface before the tip gets seated.
Start Slow And Let The Bit Cut
- Seat the tip: Place the masonry bit in the mark and start at low speed.
- Build the groove: Let the carbide tip bite before adding more pressure.
- Keep the drill straight: Hold the body square to the wall to keep the hole centered.
- Pause for dust: Back out once or twice to clear debris and cool the bit.
- Finish to depth: Stop at the tape line or depth stop, not after the anchor resists.
That sequence matters because brick fails in chips, not clean slices. The bit removes tiny grains and fragments, and the wall stays cleaner when the pressure stays even instead of jerky.
Use A Pilot Hole For Larger Openings
A pilot hole gives the final bit a path and lowers the chance of wandering on harder brick. This helps most with larger diameters, deeper holes, and older masonry where the surface has tiny voids or softer patches.
For a cable pass-through, step up in bit size gradually instead of jumping straight to a large opening. That reduces heat on the bit and keeps the edge of the hole tighter, which matters if a sleeve or grommet needs to sit flush.
Bob Vila and other home-improvement references often point to the same pattern: slow start, steady feed, clear the dust, then finish the cut. More speed creates more friction, and friction adds heat that shortens carbide life and roughens the hole.
Heat and friction are only part of the risk; technique also shapes whether the masonry stays intact.
Keeping Cracks, Spalling, And Blowout To A Minimum
Cracks usually start where the brick is thin, stressed, or already damaged. Spalling, the flaking or popping off of the face, often begins when the bit pushes too hard near an edge or weak joint.
Stay Away From Weak Zones
- Stay off corners: Corners split faster because both faces can release at once.
- Avoid thin edges: The brick has less mass there, so the surface breaks sooner.
- Skip broken joints: Loose mortar gives the bit a soft path and poor anchor support.
- Watch for hairline cracks: Existing damage can spread under drilling pressure.
- Rethink old brick: Brittle masonry may need a different mounting plan.
A pause can save the wall. Pull the bit out, clear the debris, then resume with lighter pressure instead of forcing a stalled cut deeper into the same spot.
The crack risk rises sharply on brittle or historic units because the pores, clay body, and mortar have aged in different ways. A softer brick can absorb vibration poorly, so a rotary hammer may be too aggressive unless the wall and load really call for it.
Old brick asks for restraint. A small hole in the wrong place can spread a fracture that outgrows the mount itself.
That is where wall condition drives the choice as much as tool power does. Once the surface stays intact, the next step is clearing the dust so the anchor can fit the hole the way it should.
A clean opening matters just as much as an unbroken face when the anchor has to seat properly.
Clearing Dust For A Cleaner Hole And A Better Fit
Brick dust packs into the hole like fine sand and can keep an anchor from seating fully. A vacuum, compressed air, or a squeeze bulb clears the cavity so the fastener grips the sides instead of floating on grit.
Keep Dust Out Of The Way
Wear eye protection and a dust mask, especially indoors or overhead. Masonry dust gets into the eyes fast, and fine particles hang in the air long enough to blur your view of the mark and the bit.
Good visibility helps you spot a wandering bit, a clogged fluting channel, or a cut that has stopped making progress. A quick back-out every so often keeps the hole open and lets the dust fall away before it compacts.
Check The Hole Before The Anchor Goes In
Run the vacuum nozzle over the opening, then test the depth with the anchor itself. A hole that looks deep enough can still be packed with dust at the bottom, which shortens the usable depth by more than you expect.
Compressed air works well for long holes and cable pass-throughs, but use short bursts so you do not blow dust across finished surfaces. That extra minute of cleanup pays off when the anchor seats flush and the screw starts without wobble.
With the hole clean, hardware choice becomes the final fit question. The next section sorts anchors by load so the wall holds what you plan to hang.
Even a perfectly drilled hole fails if the anchor cannot match the weight it will carry.
Picking The Right Anchor For The Load
A drilled hole alone does not hold much weight. The anchor spreads the load across more surface inside the masonry, and that spread is what keeps a screw from loosening over time.
| Use case | Anchor style | Load idea |
|---|---|---|
| Small hook or picture | Plastic masonry plug | Light fixture |
| Mirror or towel bar | Sleeve anchor | Light to medium fixture |
| Shelf bracket | Expansion or sleeve anchor | Medium load with firm bite |
| Heavy bracket or rail | Lag shield or other heavy-duty masonry anchor | Heavier hardware with more hold area |
Choose the anchor so it fits both the hole and the load. A tiny plastic plug can hold a lightweight frame, but a shelf with books needs a stronger fastener and a hole cut to the exact diameter the hardware expects.
Test the fit before hanging the item. The anchor should seat fully without spinning, and the screw should bite cleanly rather than turning the hole into a loose sleeve.
TaskRabbit and similar service platforms often get called in for heavier mounts, and that makes sense, because large loads on questionable brick or veneer belong in the zone where extra hands or a pro installer can save the wall. For smaller projects, the fit check is usually enough to tell you whether the setup is sound.
When the hardware is close but not quite right, small adjustments can prevent larger failures later.
Solving Common Problems Before They Spread
A stalled bit, a wandering hole, or a chipped edge is a signal, not a challenge to push through. The wall is telling you the cut has lost control, and the fastest fix is to stop before the damage widens.
Stalled Bit And Slow Progress
A bit that stops advancing often needs dust cleared from the flutes or a little more drill power. Back it out, vacuum the hole, then resume at low speed so the carbide edge can bite again.
Heat is another clue. A hot masonry bit cuts poorly and wears faster, so a brief pause lets both the bit and the brick cool before you continue.
Wandering Hole Or Chipped Edge
A hole that drifts off the mark often starts with an angled entry or too much pressure. Stop, reset the bit in the center of the mark, and let the tip establish the path before you lean on the drill.
A chipped rim can often be left alone on a hidden mount, but a visible face or a load-bearing bracket needs a cleaner start. In that case, shift the location to better brick rather than enlarging the damage by trying again in the same spot.
Fragile Wall Or Heavy Load
Some walls are too weak for the planned hardware, especially thin veneer, loose mortar, or brick that flakes at the touch of a fingertip. A larger anchor will not fix brittle material, and a heavier load can pull out even a well-cut hole.
That is the point where a different mounting plan makes more sense than more drilling. A spreader plate, a new location, or a pro installer can protect the wall and the item you want to hang.
Sometimes the safest fix is stepping back and choosing a different approach altogether.
Wrap Up
The cleanest result comes from matching tool, bit, wall, and anchor before the drill ever starts. A carbide-tipped masonry bit, low speed, straight pressure, and a clean hole give you the best shot at brick that stays intact and hardware that stays put.
FAQ
Can you drill into brick with a normal drill?
Yes, a small hole in sound brick is often manageable with a normal drill, especially when paired with a carbide-tipped masonry bit and slow speed. A hammer drill is the better choice for larger holes, harder masonry, or any project that needs several holes.
Should you drill into the brick or the mortar?
Brick face is the safer choice for most mounts because it gives the anchor more solid material. Mortar is softer and easier to cut, but it can crumble faster and may not hold much weight.
How do you drill into brick without cracking it?
Mark the spot clearly, start at low speed, use steady pressure, and keep the drill straight. Stay away from edges, corners, and damaged mortar, then clear dust before the anchor goes in.
What kind of drill can drill into brick?
A hammer drill is usually the better tool for brick because its pulsing action helps the bit chip through masonry. A rotary hammer goes farther for tougher jobs and deeper holes.
Why does the bit wander on brick?
The bit wanders when the surface is slick, the angle is off, or the pressure starts too hard. A small pilot hole, a clear mark, and a slow start keep the bit centered long enough to bite.
