A toggle bolt is a hollow-wall anchor made of a machine screw and spring-loaded “wings” that fold to pass through a drilled hole, then open behind drywall, plaster, or hollow masonry to clamp the material and spread load over a wide area, allowing you to hang items securely where no wall stud is available.
Torpedo level
A torpedo level is a compact, straight-edged spirit level—typically 6 to 9 inches long with tapered ends—used to check level, plumb, and often 45° in tight spaces; many models add a magnetized, V‑grooved base for gripping metal pipe or conduit, making it a go-to tool for electricians, plumbers, carpenters, and homeowners setting shelves, hardware, and fixtures accurately.
Torque wrench
A torque wrench is a hand tool that lets you tighten nuts and bolts to a specific tightness by measuring the twisting force (torque), preventing under- or over-tightening that can lead to loose parts, damaged threads, or crushed gaskets; it alerts you—by a click, pointer, or digital signal—when the target value in ft-lb or Nm is reached.
Trim router
A trim router is a compact, handheld woodworking tool with a small, high-speed motor used to shape edges, flush-trim laminates or veneers, cut shallow mortises, and perform light routing tasks; it excels at precise, one-handed work on cabinets, shelves, and small projects where a full-size router would feel bulky, heavy, or harder to control.
Trowel
A trowel is a small hand tool with a flat or shaped blade and a handle, used to scoop, spread, shape, and smooth materials like mortar, concrete, plaster, and tile adhesive; homeowners use different trowel styles for tasks such as bricklaying, tiling, patching walls, and finishing concrete, where blade size, shape, and notch pattern control coverage and surface finish.
Tubing cutter
A tubing cutter is a hand tool that slices cleanly through pipe and tubing—like copper, PEX, PVC, aluminum, or thin-wall steel—by tightening a small cutting wheel around the outside and rotating until the wall separates, producing square, burr‑light cuts that fit better, seal more reliably, and require less cleanup than a hacksaw for plumbing and HVAC projects.
V
Vacuum clamp
A vacuum clamp is a workholding device that uses a sealed suction area and a vacuum source (pump or venturi) to pull a workpiece tightly against a flat surface, pod, or mat, creating strong, even holding force for routing, sanding, drilling, CNC work, and veneering without screws or squeeze clamps.
Varnish
Varnish is a clear or lightly tinted protective finish for wood and other materials that dries to a hard, transparent film, sealing out moisture, resisting wear and UV light, and enhancing natural grain; made from resins, oils, and either solvents or water, it’s commonly used on furniture, floors, trim, cabinets, doors, and outdoor pieces to improve appearance and durability.
Vice grip
A vice grip (properly “locking pliers” and often sold as Vise‑Grip) is a hand tool with adjustable serrated jaws that clamp onto objects and lock closed using a lever mechanism, letting you grip, hold, or turn parts hands‑free until you release them—useful for loosening rounded fasteners, clamping during repairs, or holding pieces while cutting, drilling, soldering, or gluing.
Voltage tester
A voltage tester is a small handheld tool used to check whether electricity is present in a wire, outlet, switch, or appliance, helping you confirm if a circuit is live or safely off before work; models range from simple non-contact pens that sense AC fields to two-lead testers and multimeters that measure actual voltage and give visual or audible results.
W
Water level
A water level is a simple leveling tool consisting of a clear hose partially filled with water that uses gravity and the principle of communicating vessels to show the same height at both ends; it lets you transfer a level reference around corners or over long distances where a spirit level or laser can’t reach, for accurate layout indoors and outdoors.
Wet saw
A wet saw is a power tool that uses a diamond blade cooled and lubricated by water from a reservoir or pump to cut hard materials like tile, stone, and masonry, reducing dust, heat, and chipping for cleaner results; often built as a tabletop saw with a sliding tray or as a handheld unit, it delivers smooth, accurate cuts for flooring, backsplashes, countertops, and similar projects.
Wire brush
A wire brush is a hand or power-driven tool with bristles made of steel, stainless steel, brass, or abrasive nylon used to clean, deburr, and roughen surfaces by scraping with the wire tips, commonly for removing rust, paint, corrosion, and mill scale, preparing metal, masonry, or wood for finishing, and cleaning welds, threads, and tools without removing significant base material when used correctly.
Wire nut
A wire nut is a twist-on plastic cap with an internal metal spring that joins and insulates two or more electrical wires inside a junction box, forming a tight splice that resists loosening, arcing, and shorts during home wiring tasks such as connecting lights, switches, and outlets; sizes are color-coded to match wire gauge and the number of conductors.
Wire stripper
A wire stripper is a handheld tool that removes the protective insulation from electrical wire without nicking the metal conductor, using sized cutting notches or precision blades; it helps you prepare clean, accurate wire ends for connections, repairs, and installations in household circuits, low-voltage systems, and electronics while improving safety, reliability, and speed.
Wood filler
Wood filler is a sandable, paintable or stainable paste or putty-like repair compound made from binders, resins, and often wood fibers, used to fill nail holes, cracks, dents, and small voids in wood so you can create a smooth, level surface before finishing; it hardens within minutes to hours and can be shaped, drilled, or planed like wood after it cures.
Wood glue
Wood glue is a family of adhesives formulated to bond wood fibers by penetrating the grain and curing into a tough, durable film; used for furniture, trim, cabinetry, and crafts, it includes PVA “carpenter’s” glues, polyurethane, epoxy, hide glue, and CA, each offering different strength, water resistance, open time, and cleanup requirements.
Wood screw
A wood screw is a threaded fastener designed specifically to join wood to wood or to attach hardware to wood; it uses sharp, coarse threads and a tapered or partially tapered shank to cut into the fibers and pull parts tightly together as it is driven, holding securely without a nut and coming in various head shapes, drive styles, sizes, and corrosion-resistant finishes.
Workbench
A workbench is a sturdy, flat-topped table designed to support building, repairing, and crafting tasks, providing a stable surface, clamping points, and tool organization for woodworking, metalwork, electronics, and general home projects; it can be fixed or mobile, with features like vises, dog holes, shelves, and power access to make tasks safer, faster, and more accurate.
Workbench vise
A workbench vise is a mechanical clamping tool mounted to a bench that uses jaws tightened by a screw or quick-release to hold wood, metal, or plastic pieces steady so you can cut, drill, saw, plane, sand, file, or glue safely and accurately with both hands free. It improves control, repeatability, and project quality on DIY tasks.
Work light
A work light is a portable, high-output lamp that brightly illuminates a task area so you can see details, work safely, and reduce mistakes in dim or shadowed spaces; models range from corded halogen floodlights to rugged LED units with tripods, clamps, or magnetic bases for garages, jobsites, attics, crawlspaces, and outdoor projects.
Worm drive saw
A worm drive saw is a circular saw that uses a worm gear to drive the blade at lower speed but higher torque, placing the motor inline behind the blade; it’s typically heavier with a left-side blade for better cut visibility, and is favored for long, straight cuts in framing, ripping sheet goods, and cutting thick or wet lumber where steady power and control matter.
Wrench set
A wrench set is a collection of hand tools in multiple sizes designed to grip and turn nuts, bolts, and other fasteners, typically including open-end, box-end, or combination wrenches—and sometimes ratcheting or adjustable styles—so you can tighten or loosen hardware on furniture, plumbing, bicycles, appliances, and vehicles with the correct fit and leverage.
