H.B. Carbide, a manufacturer and global supplier of carbide blanks and preforms, has announced its grade HB-710 for extended cutting edge wear in machining of high temperature, nickel-based alloy and stainless steel materials.

HB-710 was developed to provide increased performance in milling and drilling of difficult-to-machine aerospace and medical applications. The grade has been engineered for an optimal balance between toughness and hardness to achieve high degrees of edge line security and resistance to corner and micro chipping, two common modes of tool failure in these applications.

"Selecting the appropriate carbide grade for machining high-temperature aerospace alloys involves considering several key factors related to the material properties and machining conditions. Technically speaking, it is about the ideal blend of toughness and wear resistance through optimized grain size and distribution of binder and additives," said Jon Wyniemko, Director of Sales for H.B. Carbide. "The result landed in the perfect sweet spot between toughness and hardness that provides long and predictable tool life in these materials."

Additionally, the submicron grain size and medium-low cobalt content of HB-710 are suited for grinding to produce the desired cutting edge geometries.

"Avoiding inconsistent performance and breakage-which can damage components in late stages of machining-eliminates scrap, downtime and the massive expense that goes along with that. A grade with this range of machining characteristics goes a long way to ensure quality and boost confidence," added Wyniemko.
