-These tools are manipulated by our hands, without using electrical energy
-Pliers, Screwdrivers, Hammers
Hand Tools
This tool is used to loosen or tighten screws with slotted heads
Screwdriver
-The blade tip of this tool is wedge-shaped and resembles a negative sign
-Used to drive screws with a single slot head
Standard / Flat Screw Driver

Used in tightening nails
Ball peen hammer
It is used in cutting, twisting, bending, holding, and gripping wires and cables
Pliers
Also called as Lineman’s Pliers
Combination Pliers
Used for gripping, holding, and cutting electrical wires, cables, and even small nails
Combination Pliers
This type of pliers is used for cutting fine, medium, and big wires and cables
Side Cutting Pliers
-This can reach tight spaces of small openings where other pliers cannot access
-Also used in making terminal loops of copper wires
Long Nosed Pliers
A tool used for removing insulation of medium size wires ranging from gauge #10 to gauge #16
Wire Stripper
