With a 1 inch cutting diameter and 0.0300 inch corner radius, it reduces stress concentrations at part corners while maintaining tight tolerances. The 10-flute geometry and 40-degree helix angle promote smooth chip evacuation and surface finish in high-speed finishing passes. An AlCrTiN coating provides thermal resistance and extended tool life under demanding cutting conditions. This is a single-end, centercutting tool, meaning it can plunge directly into workpiece material. It is installed and used by machinists and CNC tooling professionals in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish milling, contour milling, and corner-radius profiling in ferrous alloys, hardened steels, stainless steels, and similar difficult-to-machine materials. The straight-cylindrical shank fits standard collet chucks and end mill holders with a 1 inch bore. Its 1.25 inch length of cut accommodates moderate-depth axial passes without sacrificing rigidity. The HS series designation indicates a high-performance geometry optimized for stability in tight-tolerance work. This tool is commonly used on vertical machining centers and CNC mills in both roughing-to-finish and finish-only operations where corner geometry must be held precisely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300 inch corner radius reduces stress risers and produces consistent blended corners\u003c\/li\u003e\n\u003cli\u003e10-flute design increases feed rates and surface finish quality on finish passes\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating provides high-temperature hardness and oxidation resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle improves chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers hardness and wear resistance throughout tool life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for CNC machining centers and manual mills equipped with a 1 inch straight-cylindrical collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully de-energized and at a complete stop before changing tooling. Seat the shank fully in the holder to the minimum insertion depth recommended by the holder manufacturer, and torque the collet nut or set screw according to the holder specification. Verify runout with a dial indicator before beginning a cut to avoid premature tool wear or part rejection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\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: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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: 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 317277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738430996786,"sku":"317277","price":549.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bba1e3953e2d9b6d086d5fdb52e999e1.jpg?v=1788799470","url":"https:\/\/voomisupply.com\/products\/accupro-317277-corner-radius-end-mill-1-in-10-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
