How tools actually work, and how to choose one
MDF dust is treated more seriously than softwood dust because it is much finer, contains resin binders released when it’s cut, and penetrates further into the lungs. Softwood dust is coarser and mostly filtered by the nose and throat; fine MDF dust reaches deeper airways more easily. What actually makes MDF dust different? MDF is … Read more
An FFP or N95 rating tells you how well a mask filters airborne particles — dust, mist and similar solid or liquid droplets — and roughly what proportion of them it is required to stop in a standard test. It says nothing about fit on your specific face, comfort, reuse, or protection from gases, vapours … Read more
A dust mask is a loose-fitting paper or fabric shield that catches larger, visible dust and offers little protection against fine particles. A respirator is a tighter-sealing device, tested and rated to filter much finer particulates, and in some forms fitted with cartridges for fumes or vapours. The difference is the seal and the rating, … Read more
Sustained noise around 85 decibels (dB(A)) or higher is the widely used threshold at which hearing protection becomes necessary, according to occupational safety bodies. Most power saws, planers, routers and shop vacuums run well past that level, so the honest rule for a home workshop is: if a tool is loud enough that you’d raise … Read more
An eye protection rating tells you what a lens or goggle has been tested to survive and how — mainly impact from flying particles, sometimes splash, dust or radiation from processes like welding. The marking on the frame (such as Z87+ in the US or EN 166 in Europe) is a shorthand for which tests … Read more
A burnt smell from a power tool usually means one of a few things: normal carbon brushes wearing down, a motor working harder than it should because of a blunt blade or bit, a workpiece scorching under too little feed speed, or a battery or gearbox running hotter than it’s designed to. Some causes are … Read more
A featherboard is a spring-fingered jig that presses a workpiece firmly and consistently against a fence or table as it feeds through a cut. It keeps the stock tracking straight, stops it drifting or lifting, and lets you guide the wood from a position further from the blade. What Does a Featherboard Actually Do? A … Read more
Fine dust is the portion of wood or material dust small enough to stay suspended in air and reach deep into the lungs, rather than settling out like sawdust. It matters more because sawdust is visible and mostly harmless if swept up, while fine dust is invisible, breathable, and linked to long-term respiratory harm. What … Read more
A nail gun’s trigger mode changes how the tool decides to fire: in sequential mode it fires only one nail per full trigger pull, with the nose pressed down first; in contact (bump) mode it can fire every time the nose touches the work while the trigger stays pressed. The mode changes speed, control, and … Read more
Kickback is when a spinning blade or bit suddenly grabs the material or the workpiece grabs the blade, and the energy throws the workpiece back at the operator or throws the tool itself upward and backward. It happens in a fraction of a second, with enough force to cause serious injury, and it is almost … Read more
About what you read here. Everything on Find Tool is general information and our own editorial opinion. We research carefully and we say when the evidence is unclear, but we can be wrong, things change, and no article can know your particular situation. Please do your own research and make your own judgement rather than treating anything here as the final word. Prices, products and specifications around tools and workshop equipment change constantly, and what suits one person will not suit another. Check current details yourself, and where a decision involves real money, safety or something you cannot undo, it is worth confirming with the manufacturer, or a qualified electrician or tradesperson before you act.
