Pahal Inside Spring Caliper

Inside and outside calipers are precision measuring tools used in metalworking, woodworking, and various other industries to measure the internal and external dimensions of objects with accuracy and reliability. Inside calipers, also known as internal calipers, are used to measure the inner diameter of an object or the distance between two surfaces, such as the inside of a hole or the width of a groove. They consist of two legs joined at one end by a hinge and have pointed ends that can be adjusted to fit snugly against the inner walls of the object being measured.

Outside calipers, on the other hand, are used to measure the external dimensions of an object, such as its outer diameter or the distance between two outside surfaces. They also consist of two legs joined at one end by a hinge, but the ends of the legs are flat and are adjusted to fit around the outer edges of the object being measured.

Both inside and outside calipers are typically made of high-quality steel to ensure durability and accuracy. They are available in various sizes and styles to suit different measurement needs, and some models feature adjustable screws or locking mechanisms to hold the measurements in place once they are set. Inside and outside calipers are essential tools for machinists, carpenters, and metalworkers who require precise measurements in their work.
