Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed when cutting high-temperature alloys, stainless steel, and carbon steel. The tool measures 0.250 inches in diameter with a 1.750-inch length of cut, a 0.375-inch straight-cylindrical or Weldon flat shank, and a 3.563-inch overall length. Four right-hand spiral flutes at a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The centercutting geometry allows plunge entry as well as conventional peripheral milling.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations on CNC machining centers and manual knee mills in job shop, aerospace, and industrial maintenance environments. The extra-long length of cut makes it well suited for deeper pockets and slots where a standard-length tool cannot reach the full depth in a single pass. It is intended for use by machinists and tooling technicians working with high-temperature alloys, stainless steel, and steel workpieces. The Series HGC-4C designation identifies it as part of a cobalt four-flute extra-long product family from CLEVELAND.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction resists heat buildup when cutting hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eFour flutes with 30-degree right-hand helix for efficient chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eExtra-long 1.750-inch length of cut for deeper pockets and slot milling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with optional Weldon flat for secure tool holding\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with appropriate cutting fluids on ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machining high-temperature alloys, stainless steel, and steel workpieces.
