Popular YG1 55902 3/8″ Size, 1-1/2″ LOC, 4 Flute, Bright Solid Carbide Finishing End Mill

Applications

Designed for finishing operations on non-ferrous materials, the YG1 55902 3/8″ Size, 1-1/2″ LOC, 4 Flute, Bright Solid Carbide Finishing End Mill features a length of cut to diameter ratio of 4.0 that balances rigidity with precision. Its 30° helix angle paired with a bright coating and four flutes minimizes material grabbing and promotes smooth chip evacuation, making it ideal for profiling brass or bronze. The tool also delivers fine edge finishes and reduces burr formation when working with plastics such as acrylic. The sharp cutting geometry combined with a polished surface reduces friction and heat buildup, preventing melting or chipping during edge finish routing. Without a corner radius, cutting forces concentrate on the sharp edges, improving surface quality but necessitating careful use to avoid chipping in interrupted cuts. Its center-cutting design permits plunge cutting, enhancing its application versatility. Hard steels are often better machined by coated end mills. It aligns well with recommended tool-material combinations for non-ferrous metals, especially brass and plastics, where sharp, low-friction tools with moderate helix angles excel in finishing and profiling tasks.
