Twist drill is made of high-speed steel.

Vikas Singh said:   5 years ago
Option:- A and B are cutting materials.

SS is not cutting material.

Salahuddin said:   6 years ago
Stainless steel is not a cutting tool material.

But HSS and carbon steel are.

Pravinsingh said:   6 years ago
Because SS hardness is low because of low carbon content and also it is dictile material.
