It’s imperative for hobbyists and beginners to get acquainted with the functioning of all these hardware parts so as to make the best use of such tools. Moreover, one has to ensure that the quality and cost of these components is met without any compromise on the safety front.
 
Mentioned here is a list of electronic tools and equipment that are useful for every engineer while working on electronic projects:

1. Hand Tools

The most basic category of tools used in every electronic project is the hand tool. These tools are manually operated without any power source and have been in use since the Stone Age. These require a lot of dexterity as well as precision to operate. 

a) Driving Tools

Driving tools are usually used in projects while dealing with tightening, loosening, and removing the screws. These are also used to remove bits, screws, nuts, and bolts from surfaces and require manual force during operation. 

Screwdrivers:

These tools are made of hard steel and are tempered at the tip to loosen or tighten screws with slotted heads. Usually, it is recommended to purchase screw drivers in a complete set so that you have one for every kind of screw. Screwdrivers can be availed in different shapes and size, mainly including:
 
Standard/Flat Screw Driver: It is a wedge-shaped driver resembling a negative sign at the tip and is used for driving screws with a single slot head. 
 
Philips Screw Driver: It has a cross tip resembling a positive (+) sign and used to drive screws with cross slot heads.
Stubby Screw Driver: It has a short shank or blade and is used in tight spaces where a standard screw driver can’t be used.  

Wrench:

Pliers are multi-purpose tools including the following categories:
 
Nose Pliers: These come handy when you have to hold components with short leads that need to be soldered onto or desoldered from the PCB but cannot be held with bare hands. 
 
Side Cutting Pliers: These can also be used to trim off excess components on the circuit boards or to cut wires into shorter length before being used.
 
Channel Lock Pliers: These are used to tighten Romex connectors in electrical boxes, removing knockouts from the boxes and adjusting expansion-type ceiling fan boxes.
 
Linesman Pliers: These can cut, twist wires together and grip wires for pulling. They have a squared off end that is great for twisting wires, a center cutting blade and a grip area to pull wires. 

Wire Stripper:

There are certain surgical tools that can be sometimes used as electronic tools like tweezers, forceps, and scissors. While in medical settings, such tools are used to extract objects from the body, in electronics settings these tools can help in dealing with the circuits and breadboard while performing soldering or desoldering. 
 
Although tweezers and forceps are identical, the fundamental difference is that tweezers have sharper tips and these are pinched together to extract an object, while forceps have larger handles and their tips have teeth or ridged sections to grasp materials. Basically, these instruments are used to hold things that are too small to hold with hands or where precision is required.

d) Boring Tools

The process of drilling and boring implies making holes with the help of revolving tools. Boring simply pushes away the material to one side without removing it while drilling detaches the material to leave a hole. Moreover, drilling is done at high speed with low torque whereby a little material is removed at each revolution whereas boring needs low speed and high torque as it has a larger radius. These tools include:
 
Portable electric drill: boring holes in plastic or metal chassis with drill bits 
Mini drill: drilling holes in printed circuit boards
Metal files: contain a narrow, pointed and parallel ridges at one end to which a handle can be fitted.

2. Soldering Tools

While working with printed circuit boards and breadboards one needs to use some soldering tools to connect the circuits with wires and components. For this, there are soldering and de-soldering tools as follows:

a) Soldering Iron

A soldering iron is a device for applying heat to melt solder to form an electrical and physical connection between two surfaces. It is composed of a heated metal tip and an insulated handle. For electrical projects, wires are usually soldered to PCBs, other wires, or terminals. 
 
The price range lies from $10 to $200 whereby basic models can be used with easy by directly plugging them into an outlet from the hand tool. Besides, the soldering iron tips are often removable and can be availed in a wide range of shapes and styles to accommodate different kinds of soldering work.

b) Soldering Station
