Diamond core bits
Core drills are very efficient as they only cut the circumference of the hole and not the mass of material.
There are some disadvantages: The drill being used must be capable of producing high torque at low speeds.
Core drills can bind with the dust especially if water is used - regular cleaning may be required during drilling.
The most important thing to recognise is the high chance of the bit causing a 'kick back' if it jams in the hole.
For this reason a drill with a handle or preferably a clutch mechanism is a good idea - especially if the drill is being used at height!

Diamond is the hardest substance known in nature, which provides the innate condition for it to become the first choice for our drill head. Diamond is not only hard, but also naturally has multiple edges and corners. According to the different edges and corners, the strength is slightly different. The existence of edges and corners is a prerequisite for forming a cut. Secondly, the compressive strength and heat resistance of diamond are not comparable to many metals. With the above two advantages, choosing diamond as the main raw material for making diamond drill bits is a general trend. With the previous theoretical foundation, we need to use practice to prove the truth of the theory. The geological diamond core drill bit rotates at a high speed under the appropriate drilling pressure, and the diamond embedded in the cutter bit exposes the edges and corners to cut the rock. Due to the outstanding hardness and heat resistance and compression performance of diamond, the diamond can eat into the rock effortlessly. After cyclic high-speed cutting, the goal of overall footage is finally achieved, and its efficiency is unmatched by any alloy drill. In short, diamond is the hardest substance, and its status as the main raw material of cutting tools in the next century cannot be shaken, and diamond bits are only one of its many applications.
