40° - 75° ~ 30°

For β1, increase this when the tool is being used for scraping harder items (e.g., a gasket scraper).

For β2, this should be what came on the tool from the manufacturer. An estimate is given here in case it needs to be reground.

Notes & Comments
  • If grinding this on a high speed grinder, be sure to manage the temperature so that the temper is not lost due to overheating.
    • If there is a carbide insert, DO NOT cool by dipping in water. This will cause the carbide to crack due to shocks.
    • Otherwise, cool by dipping as needed in water.

  • A great general reference is the U.S. War Department's TM 9-867 Maintenance and Care of Hand Tools.
