Bi-Metal Hole Saw Set
A Bi-Metal Hole Saw Set refers to a collection of nine hole saws, each constructed with a bi-metal design. A hole saw is a cylindrical cutting tool used to create holes in various materials such as wood, metal, plastic, and more. The term "bi-metal" indicates that the hole saws are made from two different types of metals, typically high-speed steel (HSS) and a more durable alloy like cobalt. This combination enhances the hole saw's cutting performance, making it suitable for a wide range of applications and providing increased durability and longevity. The set typically includes hole saws of different sizes to accommodate various hole diameters, making it a versatile tool for professionals and DIY enthusiasts alike.
C Clamp Locking Pliers
A C clamp locking pliers, often simply referred to as locking pliers or Vise-Grips (a popular brand name), is a versatile hand tool designed for gripping, clamping, and holding objects securely. The tool features an adjustable locking mechanism that allows it to maintain a constant grip force on the object, freeing the user's hands for other tasks. The jaws of the pliers are shaped like a C-clamp, providing a strong and secure grip on various shapes and sizes of objects. This makes C clamp locking pliers particularly useful in situations where a stable hold is required, such as in woodworking, metalworking, automotive repair, and general DIY applications.
Combination spanner set
A combination spanner set typically refers to a collection of twelve different-sized spanners that feature both open-end and box-end configurations. Combination spanners are versatile tools commonly used in mechanical and household applications. The open end is designed to grip fasteners in tight spaces, while the box end provides a more secure grip on the flats of a nut or bolt.
The set usually includes a range of sizes to accommodate various fastener dimensions. Each spanner in the set may be marked with its specific size, typically in metric or imperial units. This versatile tool set is essential for tasks that require tightening or loosening nuts and bolts in different applications, providing flexibility and convenience for the user.

External Circlip Pliers Straight
External circlip pliers – straight, also known simply as external circlip pliers or snap ring pliers, are specialized hand tools designed for installing and removing external circlips or snap rings. Circlips are ring-shaped fasteners with open ends that fit into machined grooves on the outside of a shaft or bore. External circlip pliers are specifically designed to work with these types of retaining rings.
The "straight" designation indicates that the tips of the pliers are aligned in a straight line, as opposed to angled or curved tips. This straight configuration allows for easier access to circlips in certain applications.
These pliers typically have pointed or semi-circular jaws that fit into the holes or notches of the circlip, facilitating the compression or expansion of the ring for installation or removal. The handles are designed for comfortable grip and effective leverage.
Flat Hand Steel File
A Flat Hand Steel File is a type of hand tool used in metalworking and woodworking to remove material from a workpiece by abrasion.

Flat hand files are typically rectangular in shape and come in various sizes and coarseness grades, allowing for different levels of material removal and finishing. These files are commonly used for smoothing, shaping, and leveling surfaces in a variety of applications, providing a versatile means of material removal in manual craftsmanship.
Flat Wood File
A flat wood file is a hand tool used for shaping, smoothing, and refining the surfaces of wood. It typically consists of a flat, narrow, rectangular piece of metal with a series of parallel, coarse teeth or ridges along one or both of its sides. These teeth are designed to efficiently remove material when drawn across the wood grain, allowing for the leveling and smoothing of wooden surfaces. Flat wood files are commonly used in woodworking and carpentry for tasks such as shaping edges, refining contours, and removing rough spots on wood surfaces.
