2. High-speed steel - Wikipedia

   en.wikipedia.org/wiki/High-speed_steel

   High-speed steel ( HSS or HS) is a subset of tool steels, commonly used as cutting tool material . It is often used in power-saw blades and drill bits. In addition, it is often used in bowl gouges and skew for woodturning. [1] It is superior to high- carbon steel tools in that it can withstand higher temperatures without losing its temper ...

4. Tool steel - Wikipedia

   en.wikipedia.org/wiki/Tool_steel

   There are six groups of tool steels: water-hardening, cold-work, shock-resistant, high-speed, hot-work, and special purpose. The choice of group to select depends on cost, working temperature, required surface hardness, strength, shock resistance, and toughness requirements. [ 2 ]

5. List of blade materials - Wikipedia

   en.wikipedia.org/wiki/List_of_blade_materials

   Not supposed to be brittle, but high alloy steels usually are. Very expensive and hard to work. It is a martensitic stainless high-speed steel that combines the tempering, hot hardness, and hardness retention characteristics of M50 high-speed steels, with the corrosion and oxidation resistance of Type 440C stainless.

6. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

7. Annular cutter - Wikipedia

   en.wikipedia.org/wiki/Annular_cutter

   A tungsten carbide tipped (TCT) and high-speed steel (HSS) annular cutter (also known as a "core drill" or "hole saw"). 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.
