An annular cutter (also called a core drill, core cutter, broach cutter, trepanning drill, hole saw, or cup-type cutter) is a form of core drill used to create holes in metal. An annular cutter, named after the annulus shape , cuts only a groove at the periphery of the hole and leaves a solid core or slug at the center.
Cut Bakken Core samples. Although often neglected, core samples always degrade to some degree in the process of cutting the core, handling it, and studying it. Non-destructive techniques are increasingly common, e.g., the use of MRI scanning to characterize grains, pore fluids, pore spaces and their interactions (constituting part of permeability) but such expensive subtlety is likely wasted ...
Annular cutters in tungsten carbide tip (TCT) and high-speed steel (HSS) The magnetic core drilling machine utilizes core drills or annular cutters. With a cutter wall thickness of approximately 5 mm only a small amount of material around the edge of a hole is removed by an annular cutter. [4]
Truck-mounted core drill. A modern 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. Core drills used in metal are called annular cutters. Core drills used for concrete and hard rock generally use industrial diamond grit as the ...
The Rail Annular Cutters or Rail Core Drills are one of the types of Annular Cutters. These rail core drills are made from Tungsten Carbide Tip. The rail core drills are very strong and can drill hard and corroded material. [2] The rail core drills due its geometry are available only above 12 mm diameter.

A cylindrically shaped core of bone (or bone biopsy) obtained with a bone marrow trephine is usually examined in the histopathology department of a hospital under a microscope. It shows the pattern and cellularity of the bone marrow as it lay in the bone and is a useful diagnostic tool in certain circumstances such as bone marrow cancer and ...
Use for the USDC has been foreseen in the medical field, for delicate surgeries or procedures involving the human skeletal structure. Operations involving the heart cannot involve high force, which could damage the organ or surrounding rib cage. The USDC’s low axial load ensures that little to no damage would be done to these fragile areas.
