What Are Hole Making Tools Used For?

Hole making refers to a broad range of machining operations that, as the name suggests, involves cutting a hole into a workpiece using a rotary cutting tool — often in conjunction with other operations in machining a part. Machine shops and manufacturers use various cylindrical hole making tools, depending on the type of hole making operation required.

  • Drilling: This is perhaps the most recognised hole making operation. Machinists use a drill bit rotating at high speeds to cut a blind or through hole in a workpiece.
  • Reaming: Reaming is the process of enlarging the diameter of an existing hole to a high degree of accuracy, leaving behind smooth interior walls. The hole making tool used for this operation is known as a reamer.
  • Tapping: This process involves adding threading to an existing hole, allowing it to be threaded with a bolt or cap screw.
  • Boring: Unlike reamers, boring operations are done on a lathe or milling machine. This operation also enlarges the diameter of an existing hole.
  • Countersinking / Counterboring: This type of hole making operation creates a cone-shaped or square shoulder opening on the top portion of an existing hole. Countersinking / counterboring is often used to create space for the head of a screw or other type of fastener.
