It carries a 1 inch cutting diameter, a 1-7\/8 inch length of cut, and a 6-3\/8 inch overall length with a 1 inch straight-cylindrical shank that also accepts a Weldon flat drive. The spiral flute geometry runs at a 30-degree helix angle with right-hand cut and right-hand flute orientation. Center-cutting capability allows plunge entry as well as conventional peripheral milling. This tool is part of the Cleveland HD-4C series and is intended for use by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is rated for primary workpiece materials that include cast iron, non-ferrous metals, and steel. The double-end configuration provides two usable cutting ends, extending service life between tool changes. The regular-length classification and straight shank make it compatible with standard R8, CAT, BT, and collet-style toolholders commonly found on vertical milling machines and machining centers. It ships uncoated and is ready to run as received or can be used with cutting fluid for extended tool life on ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design delivers two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip evacuation on cast iron, non-ferrous, and steel workpieces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute configuration for use in standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on straight shank resists pullout under side-load cutting conditions\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction supports regrinding for cost-effective tool management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on vertical mills and machining centers with 1 inch collet or Weldon-flat toolholders.
