Why a right-angle drill helps between joists
When you need to drill sideways through a joist, a standard drill can run out of room before the bit reaches the wood. A right-angle drill places the motor behind the chuck, leaving a shorter head to fit between framing. It is useful for plumbing, electrical runs and other holes where a straight drill would hit the neighboring joist or your hand would have nowhere to go.
Measure the actual clearance, not just the joist spacing. Common framing is laid out at 16 inches on center, but pipes, blocking and existing services can leave much less room. Check the tool’s published head length and width, then allow space for the chuck, bit and your fingers. A compact right-angle drill is not automatically the right choice if the assembled tool still cannot reach the hole.

Best cordless options by job
For most between-joist work, look for a cordless right-angle drill with a compact head, a variable-speed trigger and a clutch or other torque control. Choose the battery platform you already own when possible; buying a bare tool can be cheaper than starting a second battery system. Compare the tool’s dimensions and speed range before comparing headline torque figures.
| Option | Best suited to | Main trade-off |
|---|---|---|
| Compact right-angle drill | Small pilot holes and routine drilling in tight framing | Less leverage and capacity for large bits |
| Heavy-duty right-angle drill | Larger holes, repeated work and tougher lumber | More weight, bulk and cost |
| Right-angle attachment | Occasional light drilling with a drill you already own | Can add length and may not fit the tightest spaces |
| Standard compact drill | Open bays and holes that do not need a sideways approach | Chuck and motor may collide with framing |
If you are buying specifically for framing, compare cordless right-angle drills by head dimensions, speed control and battery compatibility. For occasional small holes, an attachment may be adequate, but check its total length with your drill installed. Some combinations solve the angle problem while making the tool too long for the bay.
Choose for the bit, not the label
Small twist bits and short spade bits put less strain on a drill than large self-feed or auger bits. If you expect to bore holes around 1 inch or larger through framing, prioritize a tool intended for that work, with enough low-speed control to keep the bit from grabbing. A drill that spins fast but lacks torque control can twist your wrist when an auger catches a knot or hits a nail.
Use a sharp bit suited to wood and keep the hole within the applicable framing rules. In many common 2-by-4 bearing walls, code limits a bored hole to 40 percent of the stud depth, with stricter limits for some locations and engineered lumber. Those are not universal allowances: check local requirements and the framing type before drilling. Never bore a joist simply because a right-angle drill fits; floor joists have their own placement and size restrictions.
A clutch helps with driving fasteners, but it is not a substitute for safe control while boring. Keep both hands on the tool if the design allows, brace yourself, and stop if the bit binds. A side handle or built-in anti-kickback feature is useful on higher-torque tools, especially with larger bits.
Battery, speed and handling
For a few holes, a compact battery is easier to fit and keeps the tool lighter. For repeated large holes, a larger battery can reduce interruptions, but it adds weight at the handle and makes overhead or awkward work more tiring. If you already have compatible packs, use them rather than buying extra batteries for a job that may take only minutes.
Variable speed matters more than a high no-load speed for controlled boring. Start slowly to establish the hole, then increase speed only if the bit is cutting cleanly. If the motor stalls, do not keep pulling the trigger against a stuck bit; release it, remove the battery if needed, and back the bit out carefully. That reduces heat and lowers the chance of sudden tool rotation.
When a cheaper workaround is enough
A right-angle attachment is a reasonable low-cost choice for light, occasional drilling in an accessible bay. It is less appealing for frequent use, large bits or cramped spaces: the attachment adds length, can make the tool harder to hold square, and may not have the same capacity as a purpose-built right-angle drill. Check that the attachment’s rating covers the bit and drill speed you plan to use.
If there is enough room to use a regular drill, that is often the simplest and cheapest answer. A compact standard drill can handle pilot holes and small bits without the extra cost of a specialized tool. For tight access, browse right-angle drill attachments, but do not assume one will fit just because the drill head itself is compact.
Check before you drill
Locate pipes, cables and existing holes before drilling. Use plans, inspection openings or suitable detection tools where available; a stud finder alone cannot guarantee a bay is clear. Turn off relevant circuits before working near electrical wiring, and do not drill blindly through a wall or floor cavity. If you encounter an unexpected obstruction, stop and identify it rather than forcing the bit.
Mark the intended center and check that the bit can enter squarely. Keep chips clear, wear eye protection, and avoid loose clothing near the chuck. A clean, correctly placed hole with the right bit is safer and usually faster than trying to compensate for a dull bit, poor access or a tool that is too bulky for the space.
