What degree blade angle is used when grinding a chisel for cutting steel?

  1. 45 degrees

  2. 50 degrees

  3. 60 degrees

  4. 70 degrees

The correct answer is: 60 degrees

Grinding a chisel for cutting steel typically requires a fine edge, which is achieved with a higher degree blade angle. An angle of 60 degrees allows for a more precise and sharper edge, making it the ideal choice for cutting steel. The other options (45, 50, and 70 degrees) are not as suitable because they either do not provide enough precision or create too steep of an angle for effective cutting. It is important to choose the correct angle to ensure the chisel can effectively cut through the tough material of steel.
