2 Solid End Mill Series Kyocera's solid end mill series has a wide product lineup from roughing to finishing as well as items for difficult-to-cut materials and hardened materials. New PVD technology, MEGACOAT MEGACOAT Hard - A new coating for hardened materials. Achieves longer tool life and stable machining of hardened materials with a special multi-layer coating. MEGACOAT Hard H series P25~P26 Excellent wear resistance and heat resistance MEGACOAT Hard structure 2.μm Special multi-layer coating New coating layer (super oxidation resistance) MEGACOAT layer Super Micro-grain cemented carbide Achieves super hardness to control abrasion of the edge coating Hardness HV MEGACOAT Hard TiCN TiAlN TiN MEGACOAT Oxidation temperature( C) Smooth cutting edge quality with a unique coating technology Smooth surface quality Kyocera MEGACOAT Hard Smooth and sharp to the tip of the cutting edge. Longer tool life and improved surface finish. Competitor A Coating surface is rough and there is much cutter abrasion. The cutter edge is rounded. Competitor B Major abrasion of cutter and exposed material is noticeable. Smooth endmill surface reduces welding and allows stable machining. For high precision finishing, MEGACOAT. MEGACOAT Wear resistant and high heat resistant MEGACOAT Nitride solid solution of high melting point metal High hardness and oxidation resistant Smooth surface MEGACOAT achieves high precision finishing and a sharp cutting edge.
