A Multimeter is an electrical measuring instrument used to measure voltage, current, and resistance in electrical circuits. It is an essential tool for electricians and technicians for testing, troubleshooting, and maintenance of electrical systems. Multimeters are available in analog and digital types, with digital multimeters being more commonly used due to their accuracy and ease of reading.

A Scraper is a hand tool used for removing excess material, high spots, rust, or old paint from surfaces. It is commonly used in fitting and finishing work to achieve smooth and accurate surfaces. Scrapers are especially useful for precision work where fine material removal is required.

A Wire Brush is a hand tool used for cleaning, polishing, and removing rust, paint, or dirt from metal surfaces. It consists of a handle with tightly packed wire bristles made of steel or other metals. Wire brushes are widely used in workshops, maintenance work, and surface preparation processes.

A Tap Wrench is a hand tool used to hold and rotate taps for cutting internal threads in drilled holes. It ensures proper alignment and controlled rotation, which helps in producing accurate and clean threads. It is widely used in fitting shops, maintenance work, and mechanical workshops.

A Die Set is a hand tool used for cutting external threads on cylindrical workpieces such as rods, bolts, and pipes. It consists of a circular die held in a die stock, which helps maintain proper alignment during threading. Die sets are commonly used in fitting and maintenance work for creating new threads or repairing damaged ones.

A Tap Set is a collection of hand tools used for cutting internal threads inside drilled holes. It typically includes different types of taps such as taper tap, second tap, and bottoming tap, used in sequence to create accurate threads. Tap sets are widely used in fitting, machining, and repair work.

A Reamer is a precision cutting tool used to enlarge and finish previously drilled holes to an accurate size and smooth surface. It removes a small amount of material to improve dimensional accuracy and surface finish. Reamers are widely used in fitting, machining, and manufacturing operations.

A Counterbore is a cutting tool used to enlarge the top portion of a drilled hole to create a flat-bottomed recess. This allows bolt heads or socket screws to sit flush or below the surface. Counterbores are commonly used in fitting, machining, and assembly operations.

A Countersink is a cutting tool used to enlarge the top portion of a drilled hole to create a conical shape. This allows screws or bolts with tapered heads to sit flush or below the surface. Countersinks are widely used in fitting, machining, and assembly work.

A Twist Drill Bit is a cutting tool used for drilling holes in materials such as metal, wood, and plastic. It has a cylindrical shape with spiral flutes that help in removing chips during drilling. This is the most commonly used type of drill bit in fitting and workshop operations.
