Explanation: Carbides are not suitable for small diameters as these carbides has higher speeds and generally used in rapid stock removal.

Explanation: Stellites cannot be forged to shape easily because they are very brittle in nature.

Explanation: For ceramics, we need rigid machines. The other two mentioned disadvantages are true for diamond.

Explanation: It has excessive wear on casting and hard materials and that’s why can only perform slow and medium cutting speeds.

Explanation: Ceramic has poor shock resistant. Apart from this, it has high wear resistance and again has very high stock removal rate.

Explanation: Ceramics are used for this purpose. They are not suitable for intermittent cut and even for small diameters.

Explanation: Machine tools must be tough enough to withstand these both in order to provide stability against downward pressure and to perform the job more accurately.

Explanation: Carbides are used for these both reasons. But they are not used for comparatively small jobs.

Explanation: The answer should be none of mentioned. This is the quality of carbon steel.

Explanation: High speed steel has some advanced quality and so it is very accurate even on small diameters. So it is easy to grind high speed steel. Again, this high speed steel is generally used for intermittent cut.
