20 of the Most Frequently Used Electrical Tools
For most family unit electrical ventures, you don't require numerous claim to fame devices, and a few establishment apparatuses, similar to a mallet, measuring tape, level, and screwdrivers, you may effectively possess. ... Better electrical hand instruments, for example, wire cutters and linesman pincers, are additionally protected to help avoid stun perils.20 of the Most Frequently Used Electrical Tools:
(1) Side Cutting Pilers:

| Side Cutting Pilers |
Such a pilers is used for cutting wires, gripping operation by hand, twisting wires and number of other operation required in electrical work.
It is usually provided with snub-nosed jaws and have a cutting edge only on one side.

(3) Long Nose Pliers:
The efficient tool kit must include a long nose pliers.
It is useful for forming eyes of the wires which are to be used where they are held fast under the screw.
(4) Slip Joint Pliers:
This type of pliers is useful for conduct wiring, where its application is in the making up locknuts and bushings and holding conducts. Such a pliers has a slip joint so that its jaws can be opened to generate width.
(5) Pocket Knife:
The pocket knife is also one of the most important tools in the worker's tool kit. It is generally used for removing insulation from the wires.
The knife must be made from high grade cutlery steel. The closing type of knife should always be preferred, although a knife made from a broken hacksaw blade can serve the purpose well.
(6) Hammers:
For electrical work, generally two types of hammers are used.
(i) Claw hammer
Usually a straight claw hammer is preferred by electricians because the straight claw can be inserted behind behind beneath or between wooden board to be removed.
(ii) Ball peen hammer
The ball peen hammer is required for driving nails into wooden batten or for cutting wall plasters and bricks when it is necessary to take the wiring from one room to anther.
(7) Wooden Saw:
The house wiring is also done with wooden casing capping or batten and it is necessary to make use of a carpenter's saw for making joints or for cutting gate casing or capping.
(8) Chisels:
In house wiring, chisels are required for cutting wood and for cutting brick or concrete work. In wood work, the use of chisel is made in making various connections of casing capping, or for cutting the side of wooden board from the center in order to allow the wires to be connected to switches etc.
The wood chisel is made from tool steel.
It has a bevel at the cutting edge.
For plaster cutting or for brick cutting, cold chisels forged from allay steel are used. Before use, these chisels are tempered.
The cold chisels are generally available up to 25 mm size.
(9) Scratch Awl:
It is generally difficult to insert a wooden screw into wood, unless there is a small hole.
With a scratch awl. An impression is made into the wood before starting.
Generally it is made from forged tool steel and has a very sharp point as shown in fig. As the tool is quite sharp, much care should be taken to handle such a tool, it should never be taken in hand or pocket.
(10) Hand Drill:
In house wiring, it is often required to drill a hole in wooden blocks and wooden boards to facilitate the passage of insulated V.I.R wires which terminate into switches or other fittings.
For such purposes, a hand drill is much useful. It consists of a chuck with hardened steel jaws into which is placed the twist drill.
A crank and gear is used for increasing the speed of drill.
(11) Ratchet Bit Brace:

(11) Ratchet Bit Brace:
 |
| Ratchet Bit Brace |
Sometimes it is required to drill holes in heavy materials such as eams and joints.
For such jobs, a ratchet bit brace, as shown in fig. May be used. A ratchet bit brace with interlocking jaws ball bearing head and with 25 cm. Sweep is best suitable for electrical jobs.
But for drilling holes near the corners bit or angle brace is used as shown in fig. 1.13 with such an arrangements, the hole will be slanting.
The degree of slant depends upon the place where a hole is to be made.
(12) Anger Bits:
 |
| Anger Bits |
For new constructional work, a bit with coarse pitch of thread is to be preferred for which single spiral single cutter bit or double spiral cutter bit may be used, but single spiral cutter bit i used for easy cutting.
The clip auger or spur ear bit is used for providing holes in old house wiring, since in old houses there might be nails etc.
Driven into the wood and moreover there is not much to choose for drilling hole for wiring. The clip auger is not easily damaged by such work as compared to other types of bits.
(13) Raw Plug Tool:

| Raw Plug Tool |
One of the methods of making holes in the wall is by means of a drilling bit fixed to a holder, and into the hole so made in the wall, a raw plug is inserted. The raw plug consists of a tube of hard fiber with a central hole.
The raw plug is inserted.
The raw plug consists of a tube of hard fiber with a central hole. The raw plug and the bit are selected to the job.
(14) Hacksaw:

Hacksaw
|
For cutting metals such as conduits, cables etc., the wooden saw is not suitable and for such purpose a hacksaw as shown in fig. is used. The hacksaw frame is adjustable and carries a blade of tool steel.
The blade is usually gripped into the frame by means of wing nuts. The blade is usually 30 cm. Long with 18, 24 or 32 teeth to an inch.
The less numbered one are used for coarse jobs while more numbered ones used for fine nuts.
When cutting with hacksaw, make full strokes while pushing the saw away for you and no pressure should be applied on return stroke.
For starting, an accurate cut should be continued with a course blade.
No double the coarse blade will cut faster.
But if the cut is started with a coarse blade, the back strokes try to jump, thus spoiling the accuracy.
(15) Center Punch:
 |
Center Punch

When a hole is to be drilled in metals, the center punch is usually used for making a starting hole.
It is usually made of high grade tool hardened at both ends as shown in fig.
(16) Twist Drill:

It is capable of producing very high temperatures. Usually kerosene oil is burnt into it.
If its flame is projected directly in a job, the temperature of the job will increase to very high degree. Blow lamp as shown in fig.
(19) Files:
 |
Files
|
For wiring purposes, often we require a file removing burrs etc. For such purposes, usually a smooth half of length 30 cm size can be used.
Since its use is limited, so one file will serve the purpose.
(20) Plumb Bob:
