High speed steel tools retain their hardness up to a temperature of
A. 250°C
B. 350°C
C. 500°C
D. 900°C
Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications. ... Carbide tools can withstand higher temperatures at the cutter-workpiece interface than standard high-speed steel tools (which is a principal reason for the faster machining).so that in low speed of spindle the tool will be reduces
tool is in contact with wp for more time thus heat generated due to friction thus thermal cracking and reduces life of tool.
Sir carbide tool means
