POWER TOOOL

Apower toolis atoolthat isactuatedby an additionalpower

sourceandmechanismother than the solelymanual labour

used withhand tools. The most common types of power

tools useelectric motors.Internal combustion enginesand

compressed airare also commonly used. Other power

sources includesteam engines, direct burning of fuels and

propellants,or even natural power sources likewindor

moving water. Tools directly driven byanimal powerare not

generally considered power tools.

Power tools are used in industry, inconstruction, in the

garden, forhouseworktasks such ascooking,cleaning, and

around the housefor purposes of driving (fasteners),drilling,cutting, shaping,sanding, grinding,routing, polishing,

painting, heating and more.

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 accuracy, andsome stationary power tools can produce objects that cannot

be made in any other way. Stationary power tools for

metalworkingare usually calledmachine tools. The term

machine toolis not usually applied to stationary power tools

forwoodworking, although such usage is occasionally heard,

and in some cases, such asdrill pressesandbench

grinders, exactly the same tool is used for both woodworking

and metalworking.

ENERGY SOURCES

Currently an electric motor is the most popular choice to

power stationary tools, though in the past they were powered

by windmills, water wheels and steam. Some museums and

hobbyists still maintain and operate stationary tools powered

these older power sources. Portable electric tools may be

either corded or battery-powered.Compressed airis the

customary power source for nailers and paint sprayers. A

few tools (calledpowder-actuated tools) are powered by

explosive cartridges. Tools that run on gasoline or gasoline-

oil mixes are made for outdoor use; typical examples include

mostchainsawsandstring trimmers. Other tools like

blowtorcheswill 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 beingdouble insulatedand not earthed -

in fact theymust notbe earthed for safety reasons.

SafetyPrior to the 1930s, power tools were often housed in

cast metalhousings. 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 ofWorld 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. At this

point, the Hole-Shooter, a drill that weighed 5 lbs. wascreated 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, a former partner in the Peterson Company, in 1924

and became theMilwaukee Electric Tool Company.

In the early 30's, companies started to experiment with

housings ofthermosetpolymerplastics. In 1956, under the

influence of Dr.Hans Erich Slany,Robert Bosch GmbHwas

one of the first companies to introduce a power tool housing

made of glass fillednylon.

IMPACT DRIVER

Animpact driveris a manual or power tool that delivers a

strong, sudden rotational and downward force. In conjunction

with toughened screwdriver bits andsocket sets, they are

often used bymechanicsto loosen larger screws (bolts) and

nutsthat are corrosively "frozen" orover-torqued.The

direction can also be reversed for situations where screws

have to be tightened with torque greater than ascrewdriver

can reasonably provide.

Manual impact drivers consist of a heavy outer sleeve that

surrounds an inner core that issplinedto it. The spline is

curved so that when the user strikes the outer sleeve with a

hammer, its downward force works on the spline to produceturning force on the core and any socket or work bit attached

to it. The tool translates the heavyrotational inertiaof the

sleeve to the lighter core to generate large amounts of

torque. At the same time, the striking blow from the hammer

forces the impact driver down into the screw reducing or

eliminatingcam out. This attribute is most beneficial for

Phillips screwswhich normally cam out as part of their

design. It is also excellent for use with theRobertsonsquare

socket head screws that are in common use inCanada. It is

less beneficial forslot headscrews and is not beneficial at all

for most other types.

Impact driver guide set with bits

Powered impact drivers use a motor or compressed air to

rapidly and repeatedly deliver rotational and impact forces,

providing considerable speed and productivity advantages.

They are often used in construction and manufacturing to

replacescrewdriverswhere speed and operator fatigue are

significant issues. In some situations however, this type falls

short since current designs cannot deliver as muchdownwardblow as a manual unit. This can be especially true

on very stubbornly stuck fasteners, or screws (particularly

Phillips) with damaged/"stripped" head slots.

These are not to be confused with theimpact wrench, which

is a tool powered by a motor orcompressed air, with a

similar name and function. These also use a rotary

hammering action to applytorqueto fasteners. The

difference is that impact wrenches do not provide the

downward force and the related additional engagement that

impact drivers offer as mentioned above; otherwise the two

tools operate in essentially the same fashion mechanically.

However, while there is considerable functional overlap, they

are not interchangeable; each is particularly well-suited tocertain tasks for which the other would be a poor choice.

Ajackhammer(pneumatic drillordemolition

hammerin British English) is apneumaticorelectro-

mechanicaltool that combines ahammerdirectly with a

chisel. It was invented byCharles Brady King.

Hand-held jackhammers are typically powered by

compressed air, but some useelectric motors.

Larger jackhammers, such as rig mounted hammers

used onconstruction machinery, are usually

hydraulicallypowered. They are usually used to break

uprock,pavement, andconcrete.A jackhammer operates by driving aninternalhammer

up and down. The hammer is first driven down to strike

the back of thebitand then back up to return the

hammer to the original position to repeat the cycle. The

spring. The effectiveness of the jackhammer is

dependent on how much force is applied to the tool.

together with the use of fasteners. The attachment is gripped

by achuckat one end of the drill and rotated while pressed

against the target material. The tip, and sometimes edges, of

the cutting tool does the work of cutting into the targetmaterial. This may be slicing off thin shavings (twist drillsor

auger bits), grinding off small particles (oil drilling), crushing

and removing pieces of the workpiece (SDS masonry drill),

countersinking,counterboring, or other operations.

Drills are commonly used inwoodworking,metalworking,

construction anddo-it-yourselfprojects. Specially designeddrills are also used in medicine, space missions and other

applications. Drills are available with a wide variety of

performance characteristics, such aspowerandcapacity.

NAIL GUN

Anail gun,nailgunornaileris a type oftoolused to drive

nailsintowoodor some other kind of material. It is usually

driven byelectromagnetism,compressedair(pneumatic),

highly flammable gases such asbutaneorpropane, or, for

powder-actuated tools, a smallexplosive charge. Nail guns

have in many ways replacedhammersas tools of choice

among builders.

The first nail gun used air pressure and was introduced to

the market in 1950 to speed the construction of housing floor

sheathing and sub-floors. With the original nail gun the

operator used it while standing and could nail 40-60 nails a

minute and had a capacity of 400-600nails.
