M42 is an 8% cobalt HSS grade offering superior red hardness and wear resistance compared to standard M2 HSS, making it well-suited for harder steels, stainless steels, titanium alloys, and high-temp alloys. The end mills feature a raker-style roughing tooth profile (serrated flutes) that breaks chips into small segments, reduces cutting forces, and enables higher metal removal rates in tough materials. All five cutters have weldon-flat shanks and are finished with a black oxide steam temper treatment visible in the photos, which improves lubricity and corrosion resistance. This set is listed as new — other condition; the tools are unsharpened from the factory and appear unused, consistent with a display or overstock unit.\u003c\/p\u003e\n\u003ch3
