Why reclaimed lumber is harder to drill
Reclaimed boards can hide nails, screws, grit, dried glue and hard knots. A drill that handles clean pine may bog down in dense old oak—or send a bit sideways when it hits metal. The wood may also be dry and brittle, so holes near an edge can split even when the drill has plenty of power.
For most furniture repairs, shelving and general shop work, a good 18V cordless drill with a two-speed gearbox and adjustable clutch is enough. You do not need a hammer drill for wood. Pay more attention to bit quality, speed control and how comfortably you can hold the tool steady.

What to buy for the job
A standard drill is the most useful choice if you are making holes and driving screws in the same project. Look for a low gear around 0–500 rpm for larger bits and screwdriving, plus a high gear reaching roughly 1,500–2,000 rpm for smaller holes. A variable-speed trigger helps you start a hole without skating across the surface.
An 18V or 20V-max drill is a sensible all-rounder. Those voltage labels describe comparable battery classes, not a simple measure of drilling strength. A compact 12V drill can be easier to control and is fine for smaller bits, short screws and occasional work. It is less comfortable pushing a large bit through thick, dense timber.
Compare 18V cordless drill kits if you want one tool for mixed drilling and fastening. A kit with two batteries is useful for longer jobs, but one battery is adequate for occasional repairs. Check that the chuck accepts the bits you plan to use; a 1/2-inch chuck accommodates common larger wood bits, while many compact drills use a 3/8-inch chuck.
Drill types compared
| Tool | Best use in reclaimed lumber | Trade-off |
|---|---|---|
| Standard cordless drill | Holes, countersinks and ordinary screws | Versatile; needs steady handling with large bits |
| Hammer drill | Woodwork plus occasional masonry holes | Extra weight and cost; switch hammer mode off for wood |
| Impact driver | Driving long screws and fasteners | Fasteners drive well, but the tool is not a substitute for a drill when making clean holes |
| Compact 12V drill | Small holes, light assembly and tight spaces | Less reserve for large bits and dense stock |
If the same tool must also drill brick or concrete, a cordless hammer drill makes sense. The hammer function is for masonry, not stubborn wood: using it on timber adds vibration without helping the cut. For a wood-only project, a standard drill is usually lighter and cheaper.
Choose bits—and check for metal
For clean holes in wood, use a sharp brad-point bit for smaller, accurate holes or a spade bit for larger rough holes. Spade bits remove wood quickly but can tear out at the exit. A Forstner bit leaves a flatter-bottomed hole and cleaner edges, but it needs more torque and patience. A set of wood drill bits covering the sizes you actually use is a better purchase than a large assortment of low-quality bits.
Before drilling, inspect both faces and edges for nails and screws. A magnet can find some buried steel, though it will not reliably detect every fastener or nonferrous metal. If a bit suddenly stops cutting, chatters or throws sparks, release the trigger; do not force it. A wood bit hitting a nail can lose its edge or twist the drill out of your hand. Remove the fastener if possible, or move the hole.
Use a metal-cutting bit only after confirming the obstruction and deciding it is safe to drill through. Drilling through an unknown fastener can damage the bit and leave a sharp metal fragment in the board. For a clean project, removing the fastener is usually the better fix.
Drilling without burning or splitting
Clamp the board securely, support the back of the cut when practical, and mark the hole with an awl or a small pilot hole. Keep the drill square to the surface. Start slowly until the bit’s point catches, then increase speed while maintaining steady pressure. If the bit stops making chips and the wood starts to smell hot, back out, clear the flutes and let the bit cool.
Use low gear for large bits—roughly 1/2 inch and up is a useful point to consider low speed, though bit design and wood density matter. High gear is generally better for small bits. Avoid leaning hard on the drill: excessive pressure can stall the motor, overheat the bit or wrench the tool sideways. In dense hardwood, drill a pilot hole for screws and step up in hole size if a large bit is struggling.
To reduce tear-out, stop when the bit’s point just breaks through the far side, then finish from that side using the emerging point as a guide. Near an edge, keep a generous margin; reclaimed boards may have hidden splits that make an otherwise acceptable screw placement fail. For a screw near an end, predrill and choose a screw length that does not risk breaking through.
When to spend more—and when not to
Pay extra for a drill with a reliable clutch, a comfortable grip and a two-speed gearbox if you work with reclaimed stock often. A clutch helps prevent stripped heads and crushed wood when driving screws. A brushless motor can improve runtime and reduce maintenance, but it is not essential for occasional home projects. A basic brushed drill is fine if it has enough torque for your bits and does not overheat during normal use.
An impact driver is a useful companion for repeated long screws, especially in dense boards. It applies rotational impacts that help drive fasteners, but it is louder and can snap small screws or overdrive them. Use a drill for controlled screw placement and clean holes; consider an impact driver when driving is the main task.
For occasional shelves or a small repair, a modest drill, a sharp bit and careful clamping are enough. Spend the saved money on replacement bits if the wood is likely to contain grit or old fasteners. The best setup is the one that lets you control the cut, notice trouble early and stop before a hidden obstacle turns a simple hole into a damaged board.
