Built from micrograin solid carbide, it delivers a 1 inch cutting diameter with a 0.09 inch corner radius and a 2.25 inch length of cut. The bright uncoated finish suits applications where coating is not required or where operators prefer an uncoated substrate for specific materials. With 4 right-hand spiral flutes and a right-hand cutting direction, it provides efficient chip evacuation and consistent surface finish. Licensed machinists and CNC operators use this tool in vertical and horizontal machining centers for profiling, slotting, and contouring.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for long-reach milling applications where a standard-length tool cannot access the full depth of a feature. The 5 inch overall length and 1 inch shank diameter make it compatible with ER or shell mill holders sized for a 1 inch bore. The centercutting design allows plunge entry as well as conventional peripheral cutting. Typical use cases include deep-pocket profiling, side milling of tall workpiece walls, and contour finishing passes where a corner radius is required to blend vertical and horizontal surfaces. It is applicable in job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e0.09 inch corner radius reduces stress concentration at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes with right-hand cutting direction for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eCentercutting capable — supports direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eLong-length design at 5 inches OAL for deep-reach applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for machining centers accepting a 1 inch straight shank toolholder.

Ensure the spindle is fully stopped and locked before loading or removing the tool from the holder. Verify holder bore concentricity and runout before use, as excessive runout will accelerate edge wear and compromise dimensional accuracy. Follow the machine tool manufacturer guidelines for tool stick-out and feed-per-tooth recommendations appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: +0.0000 to -0.0025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.89 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: 12182975\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734107521330,"sku":"12182975","price":612.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85ee822a057133bb841273359fd979fd.jpg?v=1788760957","url":"https:\/\/voomisupply.com\/products\/accupro-12182975-corner-radius-end-mill-1-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
