Introduction To Saws: A Versatile Cutting Tool
Saws are essential tools for cutting solid materials, including wood, metal, and plastic. They allow us to shape and create with precision.
A saw is usually made up of a thin metal strip or disk with teeth on one edge or periphery. These teeth are arranged alternately to prevent the saw from getting stuck or bound during cutting.
The invention of the saw has brought a revolution in woodworking and various other industries. It has empowered craftsmen to accomplish tasks that were once difficult or even impossible. Saws have been crucial in advancing human civilization, from furniture making to house construction.
Different Types Of Saws For Various Cutting Purposes
There is a wide variety of saws available, each designed for specific cutting purposes. Let’s explore some of the most commonly used types:
-
Ripsaw: This saw has cutting edges that are perpendicular to the blade, allowing for efficient cuts in the direction of the wood grain. It is commonly used for ripping boards or logs.
-
Crosscut: As its name suggests, this saw is designed for making crosswise cuts. It has knifelike teeth set to alternate sides, which results in two parallel lines on each side of the kerf. This type of saw is ideal for cutting across the wood grain.
-
Backsaw: A backsaw is a crosscut saw with a rectangular blade and a heavy steel backing. The backing provides stability and support, allowing for precise cuts. Backsaws are often used for joinery work and creating intricate shapes.
-
Radial-arm saw: This powerful saw utilizes a rotating steel disk for angular and ripping cuts. It is commonly used in workshops where accurate and repetitive cuts are required.
-
Table saw: A table saw consists of a circular saw protruding through a slot in a horizontal metal table. This setup provides stability and control, making it ideal for cutting large sheets of wood or other materials.
-
Circular saw: This portable electric saw has a blade attached to a motor shaft. It is versatile and commonly used in construction sites for various cutting tasks.
-
Sabre saw: Also known as a jigsaw, this portable saw moves up and down. It is used for making curved cuts or cutting intricate shapes in wood, metal, or plastic.
-
Portable chain saw: As the name suggests, this saw is designed for felling trees. It features a thin metal frame supporting a steel roller chain with saw teeth, allowing for efficient cutting through thick logs.
Essential Characteristics Of Common Saws
While each type of saw has its own unique characteristics, there are some common features that make them effective cutting tools. The arrangement of teeth is the most crucial element. The teeth on the saw’s edge or periphery are specifically designed to efficiently cut through different materials. They vary in size, shape, and spacing depending on the intended cutting purpose.
Another essential characteristic is the set of the teeth. Most saws have teeth that are set to alternate sides, which prevents the saw from getting stuck or binding in the material being cut. This allows for smooth and continuous cutting without excessive effort.
Furthermore, saws often have ergonomic handles for comfortable grip and control. Safety features, such as blade guards and safety switches, are also incorporated in modern saw designs to protect the user from accidents.
