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.

An Electric Drill is a power tool used for drilling holes in materials such as wood, metal, plastic, and masonry. It operates using an electric motor that rotates the drill bit at high speed, making drilling faster and more efficient. Electric drills are widely used in fitting, construction, and maintenance work.

A Hand Drill is a manually operated drilling tool used to create holes in wood, metal, and plastic. It works using a gear mechanism that rotates the drill bit when the handle is turned. This tool is widely used in fitting and workshop operations where power tools are not required.

A Scriber is a hand marking tool used to draw fine lines on metal surfaces for layout work. It has a sharp pointed tip that scratches the surface, creating clear and precise markings. Scribers are widely used in fitting, machining, and metalworking operations.

A Divider is a hand marking tool used for measuring distances, transferring measurements, and scribing arcs or circles on a workpiece. It consists of two pointed legs joined at a pivot, allowing adjustment to the required distance. Dividers are widely used in fitting, layout, and workshop marking operations.

A Prick Punch is a hand marking tool used to make small, fine indentations on metal surfaces for accurate layout work. It has a sharp pointed tip with a smaller angle (usually around 30°) compared to a center punch, allowing precise marking of layout lines and reference points. This tool is commonly used in fitting and metalworking.

A Dot Punch is a hand tool used for marking small indentations on metal surfaces, typically to locate layout points or guide further machining operations. It has a sharper point compared to a center punch, allowing finer and more precise marking. This tool is widely used in fitting and metalworking for layout work.

A Plumb Bob is a simple measuring instrument used to establish a true vertical reference line. It consists of a pointed weight suspended from a string, which aligns with gravity to indicate vertical direction. This tool is widely used in construction, masonry, and surveying work
