Drill bit. From top: Spade, brad point, masonry, and twist drills bits. Drill bit (upper left), mounted on a pistol-grip electric drill. A set of masonry drills. A drill bit is a cutting tool used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create ...
A PCD coated tool may last up to 100 times longer than an uncoated tool. However, the coating cannot be used at temperatures above 600 degrees C, or on ferrous metals. Tools for machining aluminium are sometimes given a coating of TiAlN. Aluminium is a relatively sticky metal, and can weld itself to the teeth of tools, causing them to appear blunt.
End mill. An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. They can have several end configurations: round (ball), tapered, or straight are a few popular types. They are most commonly used in "milling machines" that move a piece of material against the end mill to remove chips of the material to ...
Diamond tool. A close-up of a segment of a diamond saw blade. A diamond tool is a cutting tool with diamond grains fixed on the functional parts of the tool via a bonding material or another method. As diamond is a superhard material, diamond tools have many advantages as compared with tools made with common abrasives such as corundum and ...
Titanium aluminium nitride (TiAlN) or aluminium titanium nitride (AlTiN; for aluminium contents higher than 50%) is a group of metastable hard coatings consisting of nitrogen and the metallic elements aluminium and titanium. This compound as well as similar compounds (such as TiN and TiCN) are most notably used for coating machine tools such ...
Surface finishing. A drill bit with surface finishing to make the cutting edges harder. Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. [1] Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion ...
Galling is a form of wear caused by adhesion between sliding surfaces. When a material galls, some of it is pulled with the contacting surface, especially if there is a large amount of force compressing the surfaces together. [1] Galling is caused by a combination of friction and adhesion between the surfaces, followed by slipping and tearing ...
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. [1] An annular cutter is a more expensive and efficient alternative to spiral drill bits and standard hole saws. An annular cutter is similar to a hole saw but differs in geometry and material.
