_______ composition of the carbide cutting tool is suitable for roughing operations.

_______ composition of the carbide cutting tool is suitable for roughing operations. Correct Answer High-Co

High-Co composition of the carbide cutting tool is suitable for roughing operations, whereas, low-Co compositions are used for light, high-speed machining cuts because of extremely high hardness.

Consider the following statements: 1. HSS tools wear very rapidly, whereas in cemented carbide tools, even though hardness is retained, crater wear can occur due to solid-state diffusion. 2. Cutting tools made of Super-HSS, also known as cobalt-based HSS, are made by adding 2% to 15% of cobalt which increases the cutting efficiency at heavier cuts by increasing the hot hardness and wear resistance. 3. Tools failure due to excessive stress can be minimized by providing small or negative rake angles on brittle tool materials, protecting tool tip by providing large side-cutting edge angles, and honing a narrow chamfer along the cutting edge.
