Genmitsu 1/8 Inch Shank 10pcs Carbide Spiral O Flute (Single Flute) End Mill CNC Router Bits, 91.5 Higher HRA Nano Blue Coat, perfect for Metal Carving Aluminum Copper Woodworking Cutting, OS10B

All-in-One Kit: This comprehensive set includes 10 pieces with a 1/8 inch shank size. It offers a variety of cutting diameters from 1.0 - 3.175mm (1.0/1.5/1.5/2.0/2.0/2.5/2.5/3.175/3.175/3.175) and cutting lengths from 3 - 17mm (3/8/12/8/10/12/12/9/12/17), catering to your diverse needs. Unique O Flute Design: Our Spiral O Flute (Single Flute) End Mills are well-made, producing no glitches on the surface and ensuring excellent engraving and milling performance. The design is optimized for high-volume material removal, dispersing heat more efficiently, preventing weld back. Extended Service Life: Our end mills feature a nano-blue coating for enhanced hardness. The O-Flute design ensures efficient chip removal, reducing clogging and providing smooth cutting performance. This extends the tool life, making them more durable and wear-resistant than standard end mills. Quality Craftsmanship: Using 90 percent tungsten and 10 percent cobalt, we have re-proportioned the material for aluminum usage. Unlike other flute styles with a typical hardness (HRA) around 45-50, our end mills boast an impressive HRA of 91.5, providing cleaner cuts and allowing for deeper plunges. Versatile Applications: The ultra-hardness of our cutter heads makes them highly effective when working with aluminum. Beyond that, these end mills are perfect for a wide range of applications. Whether you’re into CNC routing, hobbyist projects, sign-making with plastic and non-ferrous materials, high-efficiency milling (HEM), machining mechanical plastics, or milling through hard materials, our end mills deliver outstanding results every time.
