{{Short description|Tool that is actuated by an additional power source and mechanism other than by hand alone}}
A '''power tool''' is a tool that is [[actuator|actuated]] by an additional [[engine|power source]] and [[mechanism (engineering)|mechanism]] other than the solely [[manual labour|manual labor]] used with [[hand tool]]s. The most common types of power tools use [[electric motor]]s. [[Internal combustion engine]]s and [[compressed air]] are also commonly used. Tools directly driven by [[working animal|animal power]] are not generally considered power tools. Power tools can produce large amounts of [[particulates]], including [[ultrafine particle]]s. Airborne particulate matter is a Group 1 [[carcinogen]].

==Uses==
[[File:Hychika tools exhibition room.jpg|thumb|Diverse power tools]]
Power tools are used in industry, in [[construction]], in [[renovation]], in the garden, for [[Homemaking|housework]] tasks such as [[Outline of food preparation#Food preparation techniques|cooking]], [[housekeeping|cleaning]], and [[Do it yourself|around the house]] for purposes of driving ([[fastener]]s), [[drill]]ing, [[saw|cutting]], shaping, [[sander|sanding]], [[Grinding (abrasive cutting)|grinding]], [[router (woodworking)|routing]], [[polishing]], painting, [[metalworking]], [[woodworking]], heating and more. 

Using hand and power tools to cut plastic materials during construction activities can generate [[microplastics]]. Airborne microplastics is a type of [[particulates]]. Further studies are needed "on the different types of cutting tools and their associated MP production".<ref name=IrelandEPA>{{Citation | publisher=[[EPA (Ireland)]] | title=Sources, Pathways and Environmental Fate of Microplastics| url=https://www.epa.ie/publications/research/environment--health/Research_Report-430.pdf | section=2.3.1 and 6.2 | date=March 2023 | access-date=22 Dec 2024}}</ref>

==Classification==
[[File:A shop under renovation, with debris of construction materials all around, Tai Po, Hong Kong.jpg|thumb|upright|A shop under renovation (power tools can be seen on the left of the photo).]]
Power tools are classified as either stationary or portable, where portable means hand-held. Portable power tools have obvious advantages in mobility. Stationary power tools, however, often have advantages in speed and precision. A typical table saw, for instance, not only cuts faster than a regular hand saw, but the cuts are smoother, straighter, and more square than what is normally achievable with a hand-held power saw. Some stationary power tools can produce objects that cannot be made in any other way. [[Lathe]]s, for example, produce truly round objects.

Stationary power tools for [[metalworking]] are usually called [[machine tool]]s. The term ''machine tool'' is not usually applied to stationary power tools for [[woodworking]], although such usage is occasionally heard, and in some cases, such as [[Drill#Drill press|drill presses]] and [[bench grinder]]s, exactly the same tool is used for both woodworking and metalworking.

Many construction tasks create [[dust]]. High dust levels are caused by one of more the following:
[[File:Dust emission when using electrical power tools.webm|upright|thumb|A high dust level example.]]
* equipment – using high energy tools, such as cut-off saws, grinders, wall chasers and grit blasters produce a lot of dust in a very short time
* work method – dry sweeping can make a lot of dust when compared to vacuuming or wet brushing
* work area – the more enclosed a space, the more the dust will build up
* time – the longer you work the more dust there will be
Examples of high dust level tasks include:
* using power tools to cut, grind, drill or prepare a surface
* sanding taped [[drywall|plaster board]] joints
* dry sweeping<ref name="HSE 2023 z706">{{OGL-attribution|{{cite web | title=Frequently asked questions – Dust | website=HSE GOV.UK| date=13 Jun 2023 | url=https://www.hse.gov.uk/construction/faq-dust.htm | access-date=8 Apr 2024}} }}</ref>

Some industry standards on the size and amount of dust emitted by power tools exist,<ref>{{Cite web | url=https://standards.cencenelec.eu/dyn/www/f?p=CENELEC:110:::::FSP_PROJECT,FSP_ORG_ID:72579,1258713&cs=10E7E0D58EAE008F1E7CAC5A3EB5EED0A | title=EN 50632-1}}</ref><ref>{{Cite web | url=https://standards.cencenelec.eu/dyn/www/f?p=CENELEC:110:::::FSP_PROJECT,FSP_ORG_ID:72582,1258713&cs=18048113CC3EC59A0FB12C6D2C3A16AAF | title=EN 50632-2-5}}</ref> though it appears that they are not widely known or used globally.

Using power tools without [[Earmuffs|hearing protection]] over a long period of time can put a person at risk for [[hearing loss]].

==History==
[[File:Drive Shaft and Belts, Redbournbury Mill - geograph.org.uk - 1561145.jpg|thumb|Shaft and belt system]]
Early [[Industrial Revolution]]-era factories had batteries of power tools driven by belts from overhead shafts. The prime power source was a [[water wheel]] or (later) a steam engine. The introduction of the electric motor (and electric distribution networks) in the 1880s made possible the self-powered stationary and portable tools we know today.<ref>{{cite web|title=Modern Marvels: The World's First Power Tools|url=http://www.history.com/videos/the-worlds-first-power-tools|archive-url=https://archive.today/20130125083128/http://www.history.com/videos/the-worlds-first-power-tools|url-status=dead|archive-date=January 25, 2013|publisher=[[History (U.S. TV channel)|History]]|access-date=Oct 4, 2011}}</ref> The global market for power tools is $33&nbsp;billion (in 2016) and estimated to reach $46&nbsp;billion in 2025.

===Safety Enhancement===
Prior to the 1930s, power tools were often housed in [[metal casting|cast metal]] housings. The cast metal housings were heavy, contributing to repetitive use injuries, as well as conductive – often shocking the user. As Henry Ford adapted to the manufacturing needs of [[World War II]], he requested that A. H. Peterson, a tool manufacturer, create a lighter electric drill that was more portable for his assembly line workers.<ref name="HoleShoot">{{cite web|url=https://www.milwaukeetools.com.au/company/milwaukee-story/history-of-milwaukee|title=History of Milwaukee |publisher=[[Milwaukee Electric Tool Corporation|Milwaukee Tool Corporation]]}}</ref> At this point, the Hole-Shooter, a drill that weighed 5&nbsp;lbs. was created by A. H. Peterson. The Peterson Company eventually went bankrupt after a devastating fire and [[recession]], but the company was auctioned off to A. F. Siebert,<ref name="MilwaukeeHistory">{{Cite web|url=http://www.milwaukee-et.com/int/int_about.nsf/vwFiles/milwaukee-story/$FILE/MilwaukeesHistory.pdf?OpenElement|title=None}}</ref> a former partner in the Peterson Company, in 1924 and became the [[Milwaukee Tool|Milwaukee Electric Tool Company]].<ref>{{cite book|last=Nagyszalanczy|first=Sandor|title=Power Tools: An Electrifying Celebration and Grounded Guide|publisher=The Taunton Press|location=Newtown, CT|year=2001|isbn=978-1-56158-427-7}}</ref>

In the early 1930s, companies started to experiment with housings of [[thermosetting polymer]] plastics. In 1956, under the influence of [[Hans Erich Slany]], [[bosch (company)|Robert Bosch GmbH]] was one of the first companies to introduce a power tool housing made of glass filled nylon.<ref>{{cite book|last=Ogursky|first=Gunter|title=Design: The Quality Factor|publisher=Robert Bosch GmbH|location=Esslingen, Germany|date=<!-- unknown1 -->|isbn=<!--unknown-->}}</ref>

==Energy sources==
As of 2021, an electric motor is the most popular choice to power stationary tools. Other power sources include [[steam engine]]s, direct burning of fuels and propellants, such as in [[powder-actuated tool]]s, or even natural power sources such as [[wind power|wind]] or [[hydropower|moving water]]. In the past, stationary tools were powered by [[windmill]]s, water wheels, and steam. Some museums and hobbyists still maintain and operate stationary tools powered by these older power sources. Portable electric tools may be either corded or battery-powered. [[Pneumatics|Compressed air]] is the customary power source for nailers and paint sprayers. A few tools (called ''[[powder-actuated tool]]s'') are powered by explosive cartridges. Tools that run on gasoline or gasoline-oil mixes are made for outdoor use; typical examples include most [[chainsaw]]s and [[string trimmer]]s. Other tools like [[blowtorch]]es will burn their fuel externally to generate heat. Compressed air is universally used where there is a possibility of fuel or vapor ignition - such as automotive workshops. Professional level electric tools differ from DIY or 'consumer' tools by being [[appliance classes#Class II|double insulated]] and not earthed - in fact, they ''must not'' be earthed for safety reasons.

=== Battery types ===
Different battery powered power tools often use batteries which are not compatible across brands and models. This may cause [[vendor lock-in]], and results in poor [[sustainability]] if and when either the battery, charger, or power tool component fails, resulting in potentially all having to be replaced.

Examples of battery differences include the battery technologies themselves, with [[nickel–metal hydride battery|nickel-metal hydride]] (NiMH) and [[nickel–cadmium battery|nickel–cadmium batteries]] (Ni-Cd) being common previously,<ref>{{Cite web|url=https://www.drillsanddrivers.com/batteries/|archive-url=https://web.archive.org/web/20160218184927/http://www.drillsanddrivers.com/batteries/|url-status=usurped|archive-date=February 18, 2016|title=Battery types}}</ref> but as of 2021, [[lithium-ion battery|lithium-ion batteries]] have become the ''de facto'' standard for new power tools. The [[voltage]] is one of the most important factors for battery compatibility. In simple terms, a higher voltage rating on the tool often means that the power tool can deliver more power, with all else being equal. Using a battery with the wrong voltage rating may damage the tool, persons, or surroundings. As of 2021, 18-volt battery packs are the ''de facto'' standard in new power tools. The [[ampere-hour]], in simple terms, tells something about how long the power tool can operate before it needs to be recharged. If comparing two batteries with the same battery technology and same voltage rating, a battery with twice the amp hour rating should last about twice as long. In practice there may however be some variations to this. Also, batteries with a higher amp hour rating in practice can also often let the power tool deliver a slightly higher peak power due to the ability to deliver a higher current.{{citation needed|date=April 2021}}

Even when using the same battery technology, voltage rating and amp hour rating, the interface of batteries for power tools are often not compatible across different manufacturers, and sometimes also not even within the same brand or product line. There are examples of aftermarket adapters being made so that the user can mix and match batteries between well-known brands, but these often do not fully implement the tools battery safety and monitoring systems and the use is done at the user's own risk.

=== Battery alliances ===
There are initiatives with the goal that the same battery can be used across products from several manufacturers, mostly those who offer special tools rather than general ones. Mainly two German companies have opened their 18V systems for others:
* In June 2018, nine companies presented a manufacturer-overlapping system for rechargeable batteries called "Cordless Alliance System" (CAS).<ref>{{cite web | url=https://www.werkzeugforum.de/cas-diese-neun-firmen-nutzen-ein-gemeinsames-akku-system/ | title=CAS - Diese neun Firmen nutzen ein gemeinsames Akku-System | date=20 June 2018 }}</ref> It is based on Metabo's 18 Volt battery system.
* In 2020, Bosch initiated the "Power For All Alliance".<ref>{{Cite web|url=https://www.powerforall-alliance.com/en/|title=THE battery for your home and garden|website=POWER FOR ALL ALLIANCE}}</ref> Notably, the alliance consists of the brands [[Gardena (company)|Gardena]], Gloria,<ref>{{Cite web|url=https://www.gloriagarten.de/en/company/about-us/history/|title=Gloria: History|website=www.gloriagarten.de}}</ref> [[Wagner Electric|Wagner]]<ref>{{Cite web|url=https://www.wagner-group.com/de/unser-unternehmen/news/detail/bosch-wagner-gardena-und-weitere-hersteller-gruenden-akku-allianz/|title=Bosch, WAGNER, Gardena und weitere Hersteller gründen Akku-Allianz {{pipe}} WAGNER}}</ref> and Rapid. However, the Power For All Alliance batteries will only be used on Bosch's consumer tools in the Bosch Home & Garden line and Bosch Home Appliances line.
* ''AMPShare – powered by Bosch Professional''<ref>{{Cite web|url=https://www.ampshare.com/|title=AMPShare|website=www.ampshare.com}}</ref> is the new name for the alliance using Bosch professional ("blue") tools with its own battery and charger system which is incompatible with the Power For All batteries. Aimed at most parts of the world except North America, it claims to be based on 80&nbsp;million batteries sold since 2008. Over two dozen companies take part.
