Built from ultra-fine micrograin carbide and coated with AlCrTiN for heat and wear resistance, this tool delivers consistent performance in hardened steels, stainless alloys, and other difficult-to-machine materials. It features a 1\/2 inch cutting diameter, a 0.0300 inch corner radius, and five flutes arranged in a right-hand spiral with a 38-degree helix angle. The extended reach design and long-length configuration make it well suited for deep-pocket and profiling work where a standard-length tool cannot reach.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers for high-accuracy milling of hardened tooling, die and mold cavities, aerospace components, and precision mechanical parts. The centercutting geometry allows for plunge entry as well as full peripheral cutting. The Smart-Weldon shank type provides secure tool holding in compatible toolholders. The AlCrTiN coating supports high-speed dry or near-dry machining by reducing friction and extending tool life at elevated cutting temperatures. Installation and use are typical for professional machinists and CNC setup technicians working in job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUltra-fine micrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlCrTiN coating for heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e5-flute design for improved surface finish and higher feed rates versus 4-flute tooling\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 1-1\/4 inch length of cut and 4 inch overall length for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and right-hand cutting direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with toolholders designed for a 1\/2 inch shank diameter with an h6 shank tolerance.

Power down and lock out the machine spindle before loading or removing the tool. Seat the shank fully in the toolholder to the recommended grip length and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges and coating for damage before each use, and do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Ultra Fine Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Smart-Weldon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00000 to -0.00100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 95139027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727799648562,"sku":"95139027","price":270.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c24a02270043b8f6ecd3d1a090095fc7.jpg?v=1788682604","url":"https:\/\/voomisupply.com\/products\/accupro-95139027-corner-radius-end-mill-1-2-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
