   A man grinding on metal using an angle grinder, causing a lot of sparks. Grinding is a type of abrasive machining process which uses a grinding wheel as cutting tool. A wide variety of machines are used for grinding, best classified as portable or stationary: Portable power tools such as angle grinders, die grinders and cut-off saws

3. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. The majority of these types of cutting tools are often made from HSS (High-Speed-Steel).

4. Shear (sheet metal) - Wikipedia

   The supporting tool holder can then be made from a tougher steel, which besides being cheaper is also usually better suited to the task, being less brittle than the cutting-edge materials. The tool holders may also be designed to introduce additional properties to the cutting action, such as: angular approach – direction of tool travel

6. Milling cutter - Wikipedia

   en.wikipedia.org/wiki/Milling_cutter

   Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools).They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter).

7. Disc cutter - Wikipedia

   en.wikipedia.org/wiki/Disc_cutter

   This tool is very similar to an angle grinder, chop saw, or even a die grinder, with the main difference being the cutting disc itself (a circular diamond blade, or resin-bonded abrasive cutting wheel for a disc cutter vs. an abrasive grinding wheel for an angle grinder). This tool is highly efficient at cutting very hard materials, especially ...

8. Tool and cutter grinder - Wikipedia

   en.wikipedia.org/wiki/Tool_and_cutter_grinder

   During normal use, cutting edges either wear and/or chip. The geometric features of cutting tools can be automatically measured within the CNC tool grinder and the tool ground to return cutting surfaces to optimal condition. Significant software advancements have allowed CNC tool and cutter grinders to be utilized in a wide range of industries.
