It features a 1\/2 inch diameter, a 0.03 inch corner radius, and seven flutes with a 37-degree helix angle for aggressive chip evacuation and smooth surface finishes. The AlTiN coating provides heat resistance and extended tool life in high-speed dry cutting applications. Variable index flute spacing reduces harmonic vibration during deep cuts. This tool is intended for use by machinists and tool-and-die professionals on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits applications requiring a precise corner radius blend on pockets, slots, and contoured profiles. The 1-1\/4 inch length of cut accommodates moderate-depth side milling and full-slot operations. The single-end, centercutting design allows direct plunge entry into the workpiece. It is well suited for mold and die work, aerospace component machining, and general precision metalworking where corner strength and surface finish are critical. The right-hand cutting and right-hand spiral geometry match standard CNC spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute geometry increases feed rates and improves surface finish compared to standard 4-flute tools\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating delivers high heat resistance for dry and near-dry high-speed machining\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius with a tolerance of plus or minus 0.0015 inches for consistent blending\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and vibration in deep-cavity cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear resistance in hardened steels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1\/2 inch straight shank.

Secure the 1\/2 inch shank in a clean, properly sized collet or end mill holder and torque to the holder manufacturer specification. Verify spindle direction matches the right-hand cutting geometry before initiating a cut. Inspect the corner radius and cutting edges for chips or wear at regular intervals, particularly when machining hardened alloys at elevated feeds and speeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.307 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.13 inches height, 0.75 inches width, 0.75 inches length\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: 12178718\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748009902386,"sku":"12178718","price":131.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc557b693e71efa3d3d77151e45f5e66.jpg?v=1788887978","url":"https:\/\/voomisupply.com\/products\/accupro-12178718-corner-radius-end-mill-1-2-in-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
