3. 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.

4. Tool bit - Wikipedia

   en.wikipedia.org/wiki/Tool_bit

   Originally, all tool bits were made of high carbon tool steels with the appropriate hardening and tempering.Since the introductions of high-speed steel (HSS) (early years of the 20th century), sintered carbide (1930s), ceramic and diamond cutters, those materials have gradually replaced the earlier kinds of tool steel in almost all cutting applications.

5. Cutting tool (machining) - Wikipedia

   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).

   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).

8. Knife making - Wikipedia

   en.wikipedia.org/wiki/Knife_making

   Well equipped makers usually use a large industrial belt grinder, or a belt grinder made specifically for knife making. The standard size for a knifemakers' belt grinder is a grinder that runs a belt size of 2" by 72". Pre-polish grinding on a heat treated blade can be done if the blade is kept cool, to preserve the temper of the steel.

9. Disc cutter - Wikipedia

   Cutting sheet metal, sizing metal stock for welding, cutting a weld to re-weld it, and cutting and notching steel pipe are just a few examples. Die grinders and chop saws are other common tools used with cutting discs. Smaller projects and smaller or more precise cuts may require a die grinder equipped with a cutting wheel. These cutting wheels ...
