Built from micrograin solid carbide, it delivers a 0.375 inch cutting diameter, a 0.01 inch corner radius, and a 0.625 inch length of cut. The bright uncoated finish suits applications where coating interaction with the workpiece or cutting fluid is a concern. With four right-hand spiral flutes and a right-hand cutting direction, this stub-length tool provides rigidity and chip evacuation suited to standard machining centers and CNC mills. Machinists and toolroom professionals install this end mill in collet or end mill holders for profiling, slotting, and finishing passes requiring a controlled corner break.\u003c\/p\u003e\u003cp\u003eThis end mill fits typical milling operations on machining centers, knee mills, and CNC routers where a stub-length tool is preferred for reduced deflection. The 0.375 inch shank diameter matches standard ER collets and end mill holders common in job shops and production environments. The centercutting design allows plunge entry, expanding its use in pocket milling and ramping applications. It is appropriate for general-purpose profiling work across a range of metalworking applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003e0.01 inch corner radius reduces stress concentration at the cutting edge and workpiece corner\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with centercutting capability for plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003eStub-length profile improves rigidity and minimizes deflection in standard reach setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of cutting fluids and workpiece materials\u003c\/li\u003e\n\u003cli\u003e0.375 inch shank diameter fits standard collet and end mill holder tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8 inch shank corner radius end mill compatible with ER collet chucks, end mill holders, and milling machine spindles accepting 3\/8 inch straight shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the full recommended insertion depth in the collet or holder to prevent pullout during cuts. Verify runout with a dial indicator after tool installation, as excessive runout will accelerate edge wear and degrade corner radius accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\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\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\u003eLength Type\u003c\/strong\u003e: Stub\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 to -0.002500 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.11 pounds\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: 12182872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738568294706,"sku":"12182872","price":53.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9d329820bdedb12833b1d29433eaa9a.jpg?v=1788801103","url":"https:\/\/voomisupply.com\/products\/accupro-12182872-corner-radius-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
