WHAT IS HANDTOOLS?A

hand tool is a device for performing work on a material or a physical system using only hands.

SAFETY USE OF HANDTOOLS

Hand tools include a wide variety of nonpowered devices such as wrenches, pliers, hammers, and screwdrivers. These tools may seem harmless, but they are the cause of many injuries. The two most common hazards associated with the use of hand tools are misuse and improper maintenance.

EXAMPLE OF HANDTOOLS

Long nose pliers Side cutter Tweezers Wire stripper Screw driver

PLIERS

Function : One of commonly used tools in electronics shops cutting and gripping To bend, re-position and cut wire Given their long shape, they are useful for reaching into cavities where cables (or other materials) have become stuck or unreachable to fingers or other means

SIDE CUTTER

Good cutters are essential tool for component lead cutting and removing insulation prior to soldering or performing.

TWEEZERS

Function : Tweezers are tools used for picking up and manipulating objects too small to be easily handled with the human hands. They are probably derived from tongs, pincers, or scissors-like pliers used to grab or hold hot objects since the dawn of recorded history. In a scientific or medical context they are normally referred to as forceps.

WIRE STRIPPER

This type of wire stripper is used by rotating it around the insulation while applying pressure in order to make a cut around the insulation.

SCREWDRIVER

A screwdriver is a tool for driving screws and rotating other machine elements with the mating drive system.
