The new 301 Supreme lapidary blades have been redesigned with greater diamond concentration and a higher carbon content steel core for improved tension memory. The solid diamond sintered kerf provides for better cutting performance and improved coolant flow. Designed for cutting hard materials such as agate, petrified wood and jade.
Barranca Diamond recommends that these blades be used with petroleum, synthetic or mineral oil based coolants for best blade performance and life. Water is not suitable to use with these blades and they should not be used dry under any circumstances.
