Trusted Brand YG1 55903 1/2″ Size, 1-1/2″ LOC, 4 Flute, Bright Solid Carbide Finishing End Mill

Applications

Balancing reach and rigidity, the YG1 55903 1/2″ Size, 1-1/2″ Length of Cut, 4 Flute Bright Solid Carbide Finishing End Mill is engineered for precise profiling and finishing in non-ferrous materials. Its 30° helix angle, bright coating, and four-flute design reduce friction and minimize material buildup, enhancing surface finish quality and tool life. The absence of a corner radius allows for sharp edge cutting, ideal for applications requiring fine detail without chipping. This tool performs exceptionally in machining brass, bronze, and acrylic plastics, where polished cutting edges prevent melting and burrs. The lower helix angle helps reduce grabbing in free-machining brass, aligning with best practice recommendations. The 3.0x length-to-diameter ratio offers a good compromise between reach and stiffness for stable cutting. For steel and stainless steel, a coated end mill is typically the better choice. The bright coating and geometry are optimized exclusively for the specified non-ferrous materials.
