Mo5.8-V1.1-Cr8-Co5 Tool Steel

metal

Mo5.8-V1.1-Cr8-Co5 is a high-speed steel (HSS) variant with elevated molybdenum, vanadium, chromium, and cobalt additions designed to deliver exceptional hardness and heat resistance at cutting temperatures. This material is primarily used in precision cutting tools—including drills, end mills, taps, and saw blades—where it must withstand repeated thermal cycling and mechanical stress while maintaining a sharp cutting edge. The high cobalt content and large carbide network distinguish it from standard M-series HSS grades, making it suitable for demanding machining operations in aerospace, automotive, and general manufacturing where tool life and productivity justify the higher material cost.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
