Core Drilling Machines Key Terms

Understand the key terms relating to core drilling machines

By Howard Robertson

Core drilling machines are extremely useful for drilling holes in various surfaces, ranging from masonry to marble. These machines find applications in a wide variety of industries such as construction, and oil and gas exploration and mining.

Whether you want to manufacture these machines or use these machines for your applications, you will need to understand various technical terms that state the specifications and types of core drilling machines. This guide will cover some key terms relating to core drilling machines such as core drill bits, pneumatic drills, electric drills and RPM.

Core drill bits

A core drill bit is a tool used for drilling stone, marble, concrete and soil. These tools are available for wet or dry core drilling applications.
Try: The Ocean Drilling Program (ODP) provides detailed information about core drill bits.

Handheld drills

These lightweight drills are perfect for everyday drilling operations. Handheld drills can drill about 6" deep and are used for drilling into various materials, like concrete, asphalt and masonry.
Try: Contractors Direct, an e-shopping Web site, provides a brief description about handheld drills.

Core drill rigs

A core drill rig is useful for applications that require deeper drilling dimensions. These drills are more powerful than handheld drills and thus more suitable for commercial applications.

Pneumatic drills

Pneumatic drills are lightweight drills and can be used for surfaces that cannot be accessed easily. These drills use compressed air, thereby reducing the operator's stress.
Try: For a detailed description about pneumatic drills, you can read through an informative article at Explain that Stuff.

Electric drills

An electric drill is a drill powered by electricity. These drills are easy to use in places where an electric supply is easily available. This limits the capability of the machine for outdoor locations.
Try: diydata.com, an informatory Web site, provides detailed description about electric drills.

Drill chucks (also known as Jacob chucks)

A drill chuck is primarily used with a drilling machine, to hold the component to be drilled.
Try: For information regarding chucks, you can browse through GlobalSpec, a technical knowledge resource. To understand the basics of drill chucks, read through information at eFunda, another technical information resource.

RPM (Revolutions Per Minute)

RPM is a measure of the rotating speed of a drilling machine. It measures the number of times the shaft rotates in one minute. This is an important specification of a drilling machine, as it decides the machine's productivity.
