Built to the H1TE series specification, it features a 3\/8 inch diameter, a 0.03 inch corner radius, and four right-hand spiral flutes with a 36-degree helix angle. The AlTiN PVD coating provides thermal and oxidation resistance at elevated cutting temperatures. With an overall length of 2.5 inches and a 7\/8 inch length of cut, this single-end, centercutting tool handles both roughing and finishing operations. It is intended for use by machinists and CNC operators working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The submicron carbide grade and AlTiN coating make it well suited for high-speed and high-temperature cutting conditions common in aerospace, die and mold, and general precision machining. The 3\/8 inch straight-cylindrical shank with standard length fits directly into compatible toolholders including HC-HSK Form A style holders. Material removal type is listed as roughing and finishing, making it a versatile choice for multi-pass work on difficult workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron grade construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides oxidation and heat resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius reduces stress concentration at cutting edges and improves surface finish at part corners\u003c\/li\u003e\n  \u003cli\u003e36-degree right-hand helix with normal pitch promotes smooth chip evacuation during slotting and peripheral milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 3\/8 inch straight-cylindrical shank for direct clamping in standard collet chucks and milling toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with HC-HSK Form A toolholders.
