This cutting tool material can withstand temperatures of 1800F and higher at cutting speeds beyond those possible with other materials:

The correct choice, cubic boron nitride (CBN), stands out due to its exceptional thermal stability and hardness, which makes it an ideal cutting tool material for high-temperature applications. CBN can withstand extreme temperatures exceeding 1800°F without losing its cutting efficiency or mechanical properties. This characteristic allows for higher cutting speeds compared to other tool materials, making it suitable for machining hardened steels and other hard materials.

In addition to its thermal robustness, CBN exhibits excellent wear resistance, which prolongs tool life while maintaining precision during machining processes. This combination of heat resistance and durability enables manufacturers to achieve better performance and efficiency in machining operations, particularly in demanding environments.

Other materials, while they may have good properties, do not match the high-temperature capability and cutting speed performance of cubic boron nitride. This distinction reinforces CBN's position as the preferred choice for high-performance cutting applications.
