General purpose solid carbide end mills with HRC55 hardness, suitable for steel, alloy steel and cast iron. Optimized geometry for stable cutting, long tool life and good surface finish in CNC machining. Ideal for distributors and machining workshops looking for reliable and cost‑effective milling tools.
General Purpose Carbide End Mills (HRC55) are made from premium carbide substrate with precision-ground cutting edges, offering an excellent balance of hardness and wear resistance for most general machining tasks. With HRC55 grade, these tools deliver stable cutting performance and long tool life when machining medium to high hardness steels, carbon steel, cast iron and stainless steel, covering operations from roughing to finishing. The optimized helical flute design improves chip evacuation and heat dissipation, enabling efficient cutting at appropriate speeds and feeds while providing good surface finish and higher overall machining efficiency.jimmytool+4
