Core drills are used for several things such as when the core needs to be preserved or when the drilling can be done more rapidly because less material needs to be removed.
A core sample is a cylindrical sample of rock, soil, or ice that is obtained by drilling into the ground. It is used to study the composition, structure, and properties of the subsurface layers of the Earth. Core samples provide valuable information for various scientific disciplines, such as geology, environmental science, and archaeology.

There are several types of drilling rigs used for various drilling operations, each designed to suit specific purposes and geological conditions. Some of the most common types of drilling rigs include: Land Drilling Rigs: These are conventional drilling rigs used on land for oil and gas exploration, water wells, geothermal wells, and other drilling applications. Offshore Drilling Rigs: Offshore rigs are used to drill for oil and gas reserves beneath the seabed. They can be fixed platform rigs, jack-up rigs, semisubmersible rigs, or drillships. Rotary Drilling Rigs: Rotary rigs use a rotating drill bit to drill into the ground. They are versatile and widely used for various drilling applications. Cable Tool Drilling Rigs: Also known as percussion rigs, these rigs use a heavy drill bit that repeatedly drops and strikes the ground to break rocks. Directional Drilling Rigs: These rigs are designed to drill at non-vertical angles, allowing wells to access reserves located horizontally or in specific directions. Auger Drilling Rigs: Auger rigs use a helical screw-like drill bit to excavate materials, commonly used for environmental and geotechnical drilling. Reverse Circulation (RC) Drilling Rigs: RC rigs use dual-wall drill rods and a down-the-hole hammer for faster and more efficient drilling. Core Drilling Rigs: Core rigs are used to retrieve core samples from the ground, crucial for geological analysis and exploration. Sonic Drilling Rigs: Sonic rigs use high-frequency vibrations to drill and retrieve core samples with minimal disturbance to the surrounding soil. Hydraulic Drilling Rigs: These rigs use hydraulic power for drilling operations, commonly used for water wells and geotechnical investigations. Each type of drilling rig has its advantages and applications, depending on the geological conditions, drilling objectives, and project requirements. The choice of drilling rig depends on factors such as depth, drilling method, ground conditions, and the type of material being drilled. Pole Hole Drilling Rigs Manufacturers
Usual cause of failure in diamond core bit drilling is not following the guidelines specially indicated for the tool. It usually used the tool exceed to the preferred used of the tools so the result is breaking the material of the tool itself.
To investigate the evolution of ocean basins by core drilling of ocean sediments and underlying oceanic crust.
Exploration by drilling will result in a core sample. Brought up inside the hollow drilling tubes, the core sample is pushed out and is laid out for inspection and study.
A ship designed to reach the Earth's core is often referred to as a "deep drilling vessel" or "deep core drilling ship." These specialized ships are equipped with advanced drilling technology to penetrate deep into the Earth's crust. However, it's important to note that, as of now, no ship has successfully reached the core due to extreme temperatures and pressures. The concept of a ship reaching the core is largely theoretical and remains a topic of scientific exploration and fiction.

A core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core. Diamond core bit is commonly used in construction to create holes for pipes, manholes, and other large-diameter penetrations in concrete or stone.
That would depend on what you were drilling and what the project is.
Core drilling is usually done with a diamond tip drill bit. Diamond dust on the tip of these bits make it so you can drill through tough material such as concrete, masonry, or even tile. So to answer your question, there is not really a difference since they are essentially the same thing.
