Cutting tool materials are materials that are used to make cutting tools which are used in machining (drill bits, tool bits, milling cutters, etc.) but not other cutting tools like knives or punches. Cutting tool materials must be harder than the material of the workpiece, even at high temperatures during the process.
These cutting tools are held stationary by what is known as a tool post, which is what manipulates the tools to cut the material into the desired shape. Single-edge cutting tools are also the means of cutting material performed by shaping machines and planing machines, which remove material by means of one cutting edge.
Most coatings generally increase a tool's hardness and/or lubricity. A coating allows the cutting edge of a tool to cleanly pass through the material without having the material gall (stick) to it. The coating also helps to decrease the temperature associated with the cutting process and increase the life of the tool.
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
When machining a tough material such as stainless steel, however, shallow flutes and a squared-off cutting edge will optimize material removal and tool life. A wide variety of materials are used to produce the cutting tools. Carbide inserts are the most common because they are good for high production milling. High speed steel is commonly used ...
Tool steel is any of various carbon steels and alloy steels that are particularly well-suited to be made into tools and tooling, including cutting tools, dies, hand tools, knives, and others. Their suitability comes from their distinctive hardness , resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated ...
