An adjustable boring head is a certain kind of toolholder that we use in operation. We would use an adjustable boring head when we need to bore holes that are actually way bigger than the largest drill bit. That was the first thing I learned at my on the job training, but boring heads were far from being the last.

On the job, I learned all about the different kinds of machine tolls, which are used to shape or machine metal or other rigid materials usually through a process like cutting, grinding, shearing, or boring, which is a machining process that enlarging a hole that has already been drilled. These use a single point cutting tool, which might be held by adjustable boring heads. An example of a machine tool might be an adjustable boring head or a CNC machine, which actually uses programs to automatically execute a series of machining operations.

Every machine tool performs either one of two functions. They either constrain the workpiece, like adjustable boring heads, or they provide guided movement of the parts of the machine, like a presetter, which offer state of the art measuring. This way, they can measure the precise cuts that each machine needs with uncanny accuracy.

Do any of you have any questions or comments regarding adjustable boring heads or other machine tools? Do any of you have any experience working with them? What is it like to use boring tools? Please share your stories and experiences in the comments!
