HSS-E substrate material - The tool uses an HSS-E substrate, offering high hardness, strong wear resistance, and good hot hardness for sustained edge performance under high cutting temperatures. Steam-oxide finish - The steam-oxide finish reduces the likelihood of welding to the workpiece, minimizes built up edge, and lowers friction at the cutting edge for more reliable operation. Key benefits - Enhanced edge retention at elevated speeds and temperatures - Longer tool life in demanding metalworking tasks - Consistent cutting performance across multiple uses Applications and use scenarios - Drilling and milling steel and alloy steels where heat buildup can cause edge welding - Machining hardened or heat treated components to maintain edge sharpness and stability - Finishing passes or light cutting in metalworking tasks to reduce tool wear and prevent edge welding Compatibility and notes - Designed for use with cutting tools and holders compatible with HSS-E based substrates and steam-oxide finishes
