What brick veneer needs from a drill
Brick veneer is a facing layer, not the structural wall. It is usually separated from the house framing by a cavity, so a drill-and-anchor choice that works in solid concrete may be wrong here. The brick itself can be sound, soft, cracked or already damaged around old holes. Before drilling, identify the exact mounting location and check for electrical wiring, plumbing and other hazards on the other side.
For ordinary holes for lightweight fixtures, a compact cordless hammer drill is usually enough. Hammer action helps a masonry bit cut fired clay brick, but it does not make the tool suitable for every hole or every wall. If the job calls for a large hole, many holes, or dense material that stalls a drill, an SDS-plus rotary hammer is usually faster and less tiring. Rotary hammers use a different chuck and bit system, so they are a separate purchase rather than just a more powerful hammer-drill setting.

Choosing a cordless hammer drill
Look for a drill with a true hammer mode, variable speed and a clutch for driving screws. A 18V or 20V-class platform is a sensible general-purpose choice; the voltage label alone does not tell you how well a drill will handle masonry. Compare weight, battery availability and the manufacturer’s stated drilling capacity. A compact tool is easier to hold square against a wall, while a heavier model may offer more power but becomes tiring during overhead work.
For a few small anchor holes, a brushless motor is a nice-to-have, not a requirement. A brushed drill can do the job if its hammer mechanism is adequate and the battery is healthy. If you already own batteries in a platform, buying a bare tool is often the cheaper, more practical choice. If you need a tool and batteries, compare kit prices rather than assuming the bare drill is the better deal. Browse 18V cordless hammer drills and check the chuck capacity, included battery size and tool weight before choosing.
Hammer drill or rotary hammer?
| Tool | Best fit | Trade-off |
|---|---|---|
| Compact cordless hammer drill | A few small holes for light-duty wall anchors | Slower and more tiring in hard brick; usually takes a standard round-shank masonry bit |
| Full-size cordless hammer drill | More frequent small-to-medium holes, with one tool for drilling and screw driving | Bulkier; performance still varies with the brick and bit |
| SDS-plus rotary hammer | Many holes, larger diameters or hard masonry | More expensive and specialized; SDS-plus bits do not fit a standard drill chuck |
For a one-off project of four 6 mm holes in ordinary brick, buying a rotary hammer is often unnecessary. If a standard hammer drill barely advances after several seconds of steady pressure, forcing it can overheat the bit or motor. That is a useful point to stop and reassess, not a reason to lean harder.
Use the right bit and place the hole carefully
Use a sharp masonry bit of the diameter specified by the anchor manufacturer. A worn or general-purpose wood-and-metal bit will not cut brick properly. Standard hammer drills typically accept round-shank bits; rotary hammers need matching SDS-plus bits. Check the packaging before buying, and avoid using a bit larger than the anchor calls for: an oversized hole can leave the anchor loose.
Where possible, drill into the brick rather than the mortar joint. Brick is generally the firmer, more reliable base, while mortar can crumble and give an anchor a weak hold. Keep the hole away from the edge of the brick; drilling close to an edge raises the chance of breaking off a corner. There is no universal safe distance because brick dimensions and anchor requirements vary, so follow the anchor instructions and choose a different location if the required spacing will not fit.
Mark the location, hold the drill square, and start slowly to keep the bit from wandering. Use hammer mode for brick; turn it off for screw driving and for materials that can crack under impact. Drill only as deep as the anchor requires, allowing room for dust. A simple depth stop is helpful, but tape on the bit can also mark the target depth.
Anchors, dust and common failures
Match the wall anchor to the fixture’s weight and the brick condition. For light items, a correctly sized masonry screw or plastic masonry anchor may be adequate when installed as directed. Heavier or safety-critical loads need an anchor rated for the application and installed in sound material. Brick veneer is not a substitute for structural framing: avoid relying on it alone for a heavy awning, railing or other load that could injure someone if it pulls free. For those jobs, identify the backing and use a mounting method designed for the full wall assembly.
Dust packed into a hole can stop an anchor from seating or reduce its grip. Clear the hole with a bulb blower or suitable vacuum, and wear eye protection and a dust mask while drilling. Keep the drill steady and let the bit cut; excessive pressure can overheat it, enlarge the hole or crack the brick. If the hole suddenly gets loose, the brick flakes badly or a crack appears, stop. Moving the fixture to sound brick is safer than trying to make a damaged hole work.
For occasional anchor installation after drilling, a masonry bit set sized for common wall anchors is convenient, but a single quality bit in the exact required diameter is often the better buy for a small project.
A practical buying pick
If you need a cordless drill for household fastening and only expect to drill a handful of small holes in brick veneer, choose a platform you already own, or a midrange hammer-drill kit with a battery you can use elsewhere. Spend the savings on a sharp masonry bit and suitable anchors. A premium drill will not rescue a dull bit, a loose hole or an anchor installed in crumbly mortar.
If masonry work is regular, or your holes are larger than typical light-duty anchor holes, compare a cordless SDS-plus rotary hammer with a full-size hammer drill. The rotary hammer costs more and is less useful for routine screw driving, but it can drill hard brick more comfortably and quickly. Buy for the holes you actually make, not the largest hole listed on a package.
