![]() ![]() Horizontal or vertical milling machinesĭeep hole drilling is a specialized drilling process which creates holes with a depth-to-diameter ratio of 10:1 or more.Depending on the available equipment, machinists can drill using: The drilling process is versatile and can be used to create holes of a variety of diameters and depths. Machinists must use the correct machining strategy to evacuate chips properly rather than continuing to drill without pause. High pressure coolant will in most instances take care of this issue. It is important to note that improper chip evacuation can be a problem in this process, particularly on vertical style machines when drilling deeper holes. The depth and diameter of the hole is directly dependent on the size of the drill bit. As such, the drilling process is fairly efficient and is particularly beneficial for increasing the axial length of a hole. ![]() Working with technically smart tool salespeople is important so that you are always at the cutting edge of what is available.ĭrill bits are multi-point tools, which means they provide a minimum of two cutting edges. Manufacturers of cutting tool equipment are constantly in a state of research and development to provide their customers the most cost-effective solution. What is Drilling?ĭrilling uses a drill bit that rotates rapidly as it moves through the workpiece, effectively shaving away the solid material and creating a round hole. Drill bits are available in a comprehensive range of sizes to facilitate different hole sizes. Boring may be used to create closer tolerances and higher quality finishes in drilled holes. The drilling process creates a hole in the workpiece, while the boring process enlarges a preexisting hole. Drilling and boring are sometimes confused, but the two processes are used for different purposes. ![]()
