What stone veneer demands from a drill
Stone veneer can mean thin manufactured concrete stone, natural stone, or a masonry-look panel. The material and what sits behind it matter. A drill that handles a small hole in soft manufactured veneer may struggle with dense natural stone, and drilling too deep can damage the sheathing or a wire, pipe, or membrane behind the finish.
For a few holes for light-duty anchors, a regular cordless drill with a sharp masonry bit may be enough. For repeated holes or harder stone, a hammer drill is faster because it adds a short, rapid forward impact while the bit rotates. The impact is not a substitute for a good masonry bit: use a carbide-tipped bit rated for the material, keep it straight, and clear dust from the hole as you work.

Choosing a hammer drill
For veneer work, a compact 18V or 20V cordless hammer drill is usually the sensible choice. Look for a hammer mode, a two-speed gearbox, and a clutch that lets you use the tool as a regular drill for other tasks. A side handle is useful when drilling dense stone, though it can be bulky for small holes close to a corner. A 1/2-inch chuck gives more flexibility than a 3/8-inch chuck, but chuck capacity does not tell you how fast the drill will bore through stone.
Battery size is a trade-off. A 2.0Ah pack keeps a compact drill light for overhead work and a handful of holes. A 4.0Ah or larger pack lasts longer during repeated drilling, but adds weight. If you already own a cordless platform, a bare tool can be a better buy than another charger and battery. Compare 18V cordless hammer drills by tool weight, included side handle, and battery compatibility, not just advertised torque.
Which drill fits the job?
| Tool | Best use | Main trade-off |
|---|---|---|
| Regular cordless drill | A few small holes in soft veneer | Slower in dense stone; may overheat or stall |
| Cordless hammer drill | Several small or medium holes in masonry veneer | More vibration and weight than a standard drill |
| Rotary hammer | Many holes or larger holes in hard masonry | Usually excessive for thin veneer; impact can chip or crack it |
A rotary hammer uses a different impact mechanism and is powerful, but that can be a liability on a thin facing. For most homeowner anchor holes, start with a hammer drill and stop if the veneer begins to crack or loosen. If the project calls for a large-diameter hole, deep drilling, or many holes in very hard stone, a rotary hammer with an appropriate small bit may save time—but test in an inconspicuous spot first.
Bits and anchors matter as much as the drill
Use a carbide masonry bit sized to the anchor manufacturer’s instructions. A blunt or overheated bit skates across the face, makes an oversized hole, and can leave a ragged opening that will not hold an anchor properly. For clean starts, put a small piece of painter’s tape over the mark, use a sharp bit, and begin slowly without hammer mode. Once the bit has made a shallow seat, switch hammer mode on if the stone is resisting.
Match the anchor to the material behind the veneer, not just the visible stone. Thin veneer is often a finish layer rather than structural masonry. A plastic masonry plug anchored only in a thin facing may pull out under load. For a shelf, bracket, or other substantial load, determine whether there is concrete, brick, a stud, or another suitable substrate behind the veneer and use a fastener designed for it. If you cannot identify the backing or the load is safety-critical, do not assume the veneer itself can support it.
For a basic set of holes, a carbide-tipped masonry bit set is usually adequate. For frequent work in dense stone, consider a better-quality bit set or a single bit matched to the anchor diameter; cheap bits can wear quickly and make the job slower.
How to drill without cracking the veneer
Mark the hole away from edges, corners, and mortar joints unless the project specifically requires drilling there. Thin pieces can split more easily near an edge, and mortar may be weaker or less predictable than the stone. Check for electrical cables and plumbing before drilling. Set a depth stop or wrap tape around the bit to mark the required depth; do not drill farther than the anchor needs.
Hold the drill square to the face. Start at low speed with light pressure, then use steady pressure rather than leaning your body weight on the tool. If using hammer mode, let the tool do the work. Pull the bit out periodically to clear dust, especially in deeper holes. Dust buildup can bind the bit and heat it, while excess force can chip the stone or push through into the backing unexpectedly. Wear eye protection and a suitable dust mask, and keep people clear of the drilling area.
When to spend more—and when not to
A midrange cordless hammer drill is a good choice if you expect to drill masonry more than occasionally, need a side handle, or already use the same battery system. A budget hammer drill can be fine for a few small holes in softer manufactured veneer, provided it has hammer mode and accepts the right bit. It may take longer and be less comfortable, but buying a premium tool for four holes is hard to justify.
Pay more for a rotary hammer only when the job’s volume, hole size, or stone hardness calls for it. For ordinary veneer anchors, the better investment may be a sharp bit, the correct anchor, and careful depth control. If the veneer is loose, cracked, or unusually thin, fix the underlying problem before drilling; a more powerful drill will not make an unstable surface safe.
