Tools are one of the best categories for used purchases, with a catch: quality varies enormously, and cheap tools — whether new or used — are a waste of money. The secondhand market's value in tools is specifically in getting professional-grade tools at used prices.
Here's how to think about it by category.
Hand Tools: Almost Always Buy Used
Quality hand tools from brands like Snap-on, Mac Tools, Knipex, Wera, and Channellock are built to professional standards. A used set of these tools is better than a new set of Harbor Freight equivalents in almost every category that matters: fit, finish, material hardness, and longevity.
Wrenches and sockets — Check for obvious wear (rounded edges on hex sockets, cracked ratchet mechanisms), but good quality wrenches outlast their owners routinely. Used is almost always the right call here.
Screwdrivers — Check that tips haven't been damaged (used as chisels, stripped by overtorque). Tip condition is the main assessment point.
Pliers and adjustable wrenches — Check that the adjustment mechanism is still smooth and the jaws aren't severely worn. These are simple mechanisms that hold up very well.
Hand planes and chisels (woodworking) — These are excellent used purchases. Quality old planes from Stanley, Record, or Lie-Nielsen are often better than new economy tools. They require proper sharpening to use well, which is worth learning.
Cordless Power Tools: Buy Quality Used
The main consideration with cordless tools is the battery platform. Major platforms from DeWalt, Milwaukee, Makita, Bosch, and Ridgid have extensive tool ecosystems. Buying used tools on a platform you already own batteries for is excellent value. Buying into a new platform requires also buying batteries ($60–120 each).
What to check: The motor should run smoothly with no grinding or hesitation. The trigger should engage cleanly at low speeds. The chuck (on drills) should hold bits without slipping.
Batteries: This is the critical variable. Lithium tool batteries degrade with charge cycles, and a "dead" battery pack can make an otherwise good tool useless. Ask the seller specifically about battery condition. Replacement batteries from OEM brands are expensive; the tool needs to be priced accordingly if batteries are included and degraded.
Specific Power Tools Worth Buying Used
Table saws — A quality used cabinet saw (SawStop, Powermatic, Delta) is a better machine than a new contractor saw at double the price. These are major purchases where used quality matters most. Check the arbor bearing (no wobble), fence accuracy, and blade alignment.
Random orbital sanders, belt sanders — Inexpensive to buy new and used equivalents aren't significantly cheaper. Inspect pad condition; replacing it adds cost.
Routers — Good used routers from Porter-Cable, Bosch, or DeWalt are excellent. Check collet condition and that the depth adjustment locks properly.
Air compressors — Tank condition is the main concern (rust indicates problems). Check that the pressure relief valve functions and the compressor reaches rated pressure. Used is fine if condition is verified.
What to Approach Carefully Used
Circular saws and reciprocating saws — Safety-critical items with moving blades. Inspect blade guards carefully. Any impairment to safety guards is disqualifying.
Ladders — Never buy a used ladder. The consequences of ladder failure are severe, and visual inspection can't reveal fatigue cracks. Buy new.
Electrical measurement tools — Calibration drift is a concern with used meters. If accuracy matters for your application, verify against a known standard before relying on used test equipment.
The overall principle: quality used tools from professional brands are almost always better than new budget tools. The used market is where you access professional tool quality at accessible prices.
