Drill, Rotary Tool or Detail Sander: Which Fits a Small Woodworking Project?

Pick the tool by the job you're doing next, not by how small the project is. A drill makes holes and drives fasteners. A detail sander smooths corners and tight surfaces you can reach with its pad. A rotary tool handles small detail work, but only when its accessory suits the task and fits the tool.

None of these tools replaces the others, so don't look for one overall winner. List the jobs your project actually needs, then match a tool to each one. This woodworking tool comparison goes through each tool's role, the limits that change your choice, and how they can work at different stages of one build.

Choose a drill for holes or fasteners

If your next step is structural assembly or driving fasteners, you need a drill. While miniature bits can drill tiny holes in craft materials with a rotary tool, standard woodworking holes and screw-driven joinery require a drill. Sanders and abrasive attachments wear surfaces down rather than boring clean holes or seating fasteners.

Before you start, write down three things: the exact operation, the bit or driver accessory you'll use, and the wood you're working. Pilot holes, through-holes and driving screws can each need a different bit. Your drill's instructions set the limits that matter here. They tell you which bits the chuck accepts and how the tool should be set and handled for the material. No general rule covers every drill, so your model's manual has the final word on capacity and settings.

If your project needs holes or assembly, compare compact power drill options against the bits and materials on your list. To match motor power to the job, matching driver power to project size explains how torque and runtime relate to project scale.

A drill is the wrong choice when the job is smoothing a surface or shaping a small detail. Those jobs need an abrasive tool.

Choose a rotary tool for localized detail work

A rotary tool makes sense when sanding or shaping is small, detailed, or hard to reach. It handles spots a flat pad cannot follow, such as curved profiles or grooves. Beyond those tight contours, larger flat surfaces belong on other sanders.

According to Dremel's beginner guide to detail sanding, many woodworkers use oscillating tools on flat surfaces and rotary tools for detailed, hard-to-reach spots like decorative chair legs. The guide pairs accessory types with specific tasks: flap wheels for contoured profiles, abrasive brushes for grooves, and sanding bands for edges or rough shaping. Treat this as task-fit guidance rather than a universal material-removal rating.

Accessory fit decides whether a rotary tool is usable for your job. Run two checks:

1. Task and material. Pick an accessory made for the job, such as a flap wheel for contours or a brush for grooves, and confirm it's rated for wood.
2. Shank size. Measure the accessory's shank and compare it with the collet or chuck on your exact tool. For example, Dremel says the supplied 1/8-inch collet on its Dremel 4000 accepts 1/8-inch-shank accessories. Other shank sizes on that model need the matching collet or a separately sold keyless chuck. That spec belongs to one model and isn't an industry standard. Other rotary tools use different collet sizes.

If the shank doesn't match your collet or chuck, don't use the accessory. Get the correct collet or a compatible accessory. When you compare cordless rotary tool options, check each kit's listed collet size against the accessories you plan to use.

Choose a detail sander for small surface sanding

A detail sander fits surface prep in tight spots like inside corners, meeting angles, or small panels. Its small vibrating head and triangular sandpaper attachment reach areas that larger orbital or belt sanders miss. Also known as a corner, delta, or mouse sander, designs and pad shapes vary across models.

Before you buy, check the pad shape and size against your actual corner. Also check which abrasive sheets fit it and the grits you plan to use. If the pad can't reach the area, you're back to hand sanding or a rotary accessory. For large flat areas, a small pad slows you down, and the guide points to bigger sanders for that work.

Plan for dust. OSHA's woodworking dust guidance states that sanders, shapers, and routers generally produce the greatest amount of dust. That statement comes from workplace rough-mill guidance, not a home-shop rule. Still, it's a good reason to choose a sander with the dust collection your manual describes and to follow that manual's protection instructions.

Use different tools at different project stages

Consider a small wooden chair project. A drill handles the assembly holes and screws, while a detail sander smooths the inside corners where seat and rails meet. A turned or decorative leg with curves and grooves is where a rotary tool with a flap wheel or abrasive brush fits best.

That's three different jobs, so you'd use three different tools. Things change if the chair has no curved details. Then the rotary tool step may not exist at all. Corner sanding is less clear-cut, because both the detail sander and some rotary accessories can handle it. Let pad reach and the accessories you already own decide that step. Buy only for the stages your project really includes.

FAQs

How can I check whether a rotary-tool sanding accessory fits?

Find the accessory's shank diameter on its package or listing, then compare it with the collet or chuck your exact tool uses. A mismatch means you need a different collet, an adjustable chuck if your tool supports one, or a different accessory. A 1/8-inch accessory that fits one brand's standard collet won't automatically fit a tool built around another size.

Does workplace wood-dust guidance apply directly to a home workshop?

Not directly. OSHA wrote its eTool for woodworking workplaces, and it doesn't set home exposure limits or describe a complete home-shop setup. It's still useful context: sanding is one of the dustier woodworking tasks. Follow the dust-collection and protection instructions in your sander's manual.

Do I need all three tools for a small project?

Only if the project includes all three kinds of work. A simple box with screws and flat sides may need just a drill plus hand sanding or a sander. A piece with carved or curved details adds a rotary tool step. List the operations first. Then add a tool only for a step that nothing you already own can handle.

Can a rotary tool replace a drill for assembly?

No. While rotary tools can bore miniature holes in light craft pieces with dedicated micro bits, driving fasteners and joining wood pieces requires a drill.
