What we cover
The short answer
For ordinary joist work, a standard cordless drill is the better first buy. It drills pilot holes and drives many common screws well, and it is useful for far more than framing. A right-angle drill earns its place when the space between joists, against a wall, or inside a cabinet prevents a regular drill from lining up with the hole.
The tool choice matters less than using the right bit, keeping the hole centered, and controlling the drill when a large bit catches. If you’re drilling only a few accessible holes or fastening smaller hardware, borrow or buy a standard drill. If you routinely bore holes through joists in tight spaces, a right-angle drill can save awkward setups and reduce the temptation to drill at a poor angle.

What each tool does
A standard cordless drill has a straight chuck and is usually the most versatile option for drilling pilot holes, driving screws, and general household work. Its long body needs room behind the bit, though. Between joists or close to a wall, the drill body can hit an obstruction before the bit reaches the right spot.
A right-angle drill puts the chuck at 90 degrees to the motor body. That shorter profile lets you drill in cramped framing bays. It is primarily a drilling tool, not a replacement for an impact driver when driving lots of long structural screws. Some models have a keyed chuck for larger bits; others use a keyless chuck. Check the chuck capacity and the manufacturer’s instructions before choosing bits.
Quick comparison for joist work
| Consideration | Standard cordless drill | Right-angle drill |
|---|---|---|
| Best use | Accessible holes, pilot holes, general drilling and fastening | Drilling where a straight drill will not fit or line up |
| Access | Needs room for the drill body behind the bit | Fits better in narrow bays and near obstructions |
| Versatility | High; useful across many household jobs | More specialized; less convenient for ordinary screwdriving |
| Catch risk | A large bit can twist the drill and your wrist | A large bit can also bind; the handle position can make reaction forces surprising |
| Buy it when | You need one general-purpose drill | You regularly need to drill where a standard drill cannot fit squarely |
Choose by the job, not the name
For small pilot holes or modest holes in accessible joists, a regular drill is usually enough. Match the bit to the material and screw: a pilot hole that is too small raises the chance of splitting wood or breaking a screw; one that is too large weakens the screw’s bite. Follow the fastener maker’s pilot-hole guidance where available, especially for structural screws.
For bigger holes, use a sharp bit intended for wood, such as an auger bit or a self-feed bit when the tool and job are suited to it. A hole saw is useful for larger clean openings, but it can bind as its teeth grab. Keep the drill square, use a low gear and controlled speed, and stop if the bit stalls. Do not lean your body weight into a bit that has jammed.
Before drilling a joist, check local code and the joist manufacturer’s rules. Engineered I-joists and other manufactured joists have specific permitted hole zones and size limits; do not apply solid-lumber rules to them. For solid-sawn joists, hole placement and diameter are also restricted by code. Check for wiring, plumbing, and ducts before boring, and use the framing plan or an appropriate detector rather than guessing.
When a right-angle drill is worth buying
Buy a right-angle drill if the work itself repeatedly blocks a standard drill: for example, holes through joists in a shallow crawlspace, between closely spaced framing, or near a wall where the straight drill body cannot stay in line. An cordless right-angle drill is especially useful when you need to bore several holes rather than one awkward hole.
It is not automatically safer. A large bit can still snag, and a right-angle body may turn unexpectedly if the bit catches. Use a side handle if supplied and required by the manual, hold the tool with both hands when possible, and keep your wrists out of the likely rotation path. A clutch helps control screwdriving but does not make a jammed auger bit harmless.
For a single tight-access job, renting or borrowing one is often the sensible choice. For occasional accessible holes, put the money toward a good general-purpose drill or a sharp bit instead. A cordless drill/driver is the better-value starting point for most homeowners.
Setup that prevents bad holes
Mark the hole center clearly and check the intended location from both sides if you can. Confirm the permitted hole size and location for that specific joist. Keep holes centered across the joist’s width where the applicable rules require it, and stay clear of notches, cracks, and existing holes. If a proposed hole would exceed the permitted size or land in a restricted zone, stop and reroute the work rather than enlarging it.
Choose low gear for large bits, if the drill has two gears, and use a steady, controlled feed. High speed with a large bit can overheat the bit, burn wood, or make a catch more violent. Back the bit out occasionally to clear chips, particularly in deep holes. Wear eye protection; overhead drilling also calls for protection against falling dust and chips.
For screw fastening, drill a pilot hole when the screw maker calls for one or when the wood is prone to splitting. A regular drill works for a small number of screws. If you have many long screws, an impact driver can be less tiring, but use the correct bit and avoid overtightening or stripping the head. Do not use an impact driver as a substitute for a drill bit that requires a conventional chuck or for boring large holes unless the bit and tool are explicitly rated for that use.
What to check before buying
Compare chuck capacity, low-speed control, handle options, battery compatibility, and the tool’s stated suitability for the bit sizes you plan to use. A compact tool may fit better but have less capacity for demanding boring. Battery platform matters if you already own compatible tools; buying into a second system for one occasional joist hole is hard to justify.
If you are unsure, start with a standard cordless drill and a quality wood bit for accessible work. Step up to a right-angle drill when access—not lack of power—is the recurring problem. That distinction keeps the purchase practical and helps avoid forcing either tool into a job it cannot safely reach.
