Drilling machines, also known as drill presses, are essential tools in any machine shop. These versatile devices can perform various machining operations, predominantly drilling holes. However, their functionality extends to reaming, tapping, counterboring, countersinking, and spot-facing when paired with the appropriate tooling. Of the numerous configurations available, three primary types of drilling machines stand out: upright sensitive drill presses, upright drill presses, and radial arm drill presses. Understanding these types, along with an embedded reference to underground drilling machines, can provide a comprehensive perspective on their strengths and applications.

Upright Sensitive Drill Press

The upright sensitive drill press is a light-duty machine designed for moderate-to-light work applications. Its key feature is the belt drive spindle head, which allows for manual hand-feeding of the tool. This manual feeding method is where the term "sensitive" originates, as it enables the operator to "feel" the cutting action, providing precise control over the drilling process. Upright sensitive drill presses are available in both floor and bench styles, making them suitable for varied workshop environments.

In industrial settings, these machines are invaluable for tasks that require a high degree of precision but involve relatively small workpieces. Due to their sensitivity and control, they are often used in creating small holes or performing delicate operations. Despite their light-duty categorization, these machines are robust and reliable for specific, precision-focused tasks.

Upright Drill Press

Contrasting the sensitive variant, the upright drill press is a heavy-duty machine designed for larger hole-producing operations. It typically features a geared drive spindle head, which accommodates both manual and power feeding mechanisms. The power feed option can automatically advance the tool into the workpiece, enhancing efficiency and reducing operator fatigue during lengthy drilling processes.

Upright drill presses are suited for operations involving large or heavy parts, thanks to their considerable power and stability. Some models also come with automatic table-raising mechanisms, further simplifying the handling of substantial workpieces. These attributes make the upright drill press a staple in industries where large-scale, repetitive drilling operations are frequent.

Radial Arm Drill Press

The radial arm drill press is often considered the workhorse of the drilling world. This machine allows the spindle to be positioned directly over the workpiece, eliminating the need to move the workpiece itself. This design offers significant versatility, especially when dealing with parts too large to position easily. Radial drills also have power feed capabilities and automatic mechanisms for raising or lowering the radial arm.

The radial arm drill press excels in scenarios requiring extensive reach and flexibility, such as machining large components or drilling intersecting and angular holes. The machine's ability to traverse the spindle along the radial arm adds another layer of convenience and versatility, making it indispensable in many manufacturing environments.

Underground Drilling Machines

In addition to these three major types of surface drilling machines, it is crucial to mention underground drilling machines, which play a vital role in mining and geological exploration. These machines are specifically designed to operate in subterranean conditions, drilling deep into the earth to extract minerals or gather geological data. Their robust construction and advanced technology ensure reliable operation in the challenging and often harsh conditions found underground. These specialized machines highlight the diverse range of applications and environments in which drilling technology is pivotal.

Underground drilling machines, while not typically found in traditional machine shops, underscore the breadth of drilling technology's applications. From creating tunnels to mining valuable resources, these machines are engineered to perform under extreme conditions, showcasing the versatility and innovation within the drilling industry.

In conclusion, each type of drilling machine—upright sensitive, upright, and radial arm—serves distinct purposes, catering to different scales and precision requirements of drilling operations. Meanwhile, underground drilling machines expand the scope of this technology, demonstrating its essential role in both industrial and geological settings. Understanding these machines' unique features and applications is key to selecting the right tool for any drilling task.
