For the machinists and workshop pros out there, this YG-1 cobalt steel square nose end mill is a real workhorse. It's a long-length tool, which means it has a longer cutting edge (1.34375 inches overall) for those deeper cuts where a standard end mill just won't reach. It features three flutes—a sweet spot that gives you better chip clearing than a 4-flute and a nicer finish than a 2-flute, sometimes even saving you a finishing pass. It's center-cutting, so you can plunge right into material like a drill bit. The cutting diameter is 0.125 inches (1/8\), with a shank diameter of 0.25 inches and a Weldon shank for a solid grip in the holder. Made from tough cobalt steel, it handles heat and abrasion way better than regular high-speed steel, so you can run it faster and it stays sharp longer. The 30-degree helix angle makes it a great all-rounder for a variety of materials. It comes with an uncoated (bright) finish for maximum versatility. If you're doing detailed milling, profiling, or need a reliable tool for general-purpose jobs, this end mill is a solid pick from a trusted brand.
