CP Carbide has developed specific grades that will enhance and offer long life performance of the bit. The balance of grain size and binder content gives the desired user results.  New technologies, like binder wetting to the macro grain and HIP sintering have dramatically improved tool performance.   You can choose from many geometric designs that will improve tool performance and tool life.  The grade of steel in the bit provides the strength properties.  Using high temperature braze alloy gives the user the most strength possible, while offering heat treating when the braze joint is formed. The holder or block should be made of a high strength alloy steel.  Many of the block systems are welded directly to the machine drum or rotor so the steel properties of the holders should be weldable and also maintain high strength properties to hold them for long life on the drums.  The holding systems should have as much wear protection as possible to avoid premature wear deterioration and failure.  The ability to change the holding system in the field is important to reduce the cost and down time due to equipment changes.
