Built from solid carbide and coated with AlTiN via a PVD process, this tool handles both roughing and finishing passes. It carries a 1\/4 inch mill diameter, a 3\/4 inch length of cut, and a 0.06 inch corner radius, making it well suited for miniature and tight-tolerance work. The 4-flute, right-hand spiral geometry and 30-degree helix angle promote efficient chip evacuation and a consistent surface finish across a wide range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits into the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series. It is intended for use in CNC machining centers and manual mills equipped with compatible toolholders that accept a 1\/4 inch straight cylindrical shank. Typical applications include contouring, slotting, and profiling where a defined corner radius is required to reduce stress concentrations or meet print tolerances. The centercutting design allows plunge entry. Machinists working in job shop, aerospace, medical, and general manufacturing environments regularly select this geometry for P, M, K, N, and O material classifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating extends tool life in high-heat ferrous and stainless steel cuts\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius with a tolerance of plus or minus 0.001 inch for consistent part geometry\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral with normal pitch for stable, predictable cutting forces\u003c\/li\u003e\n  \u003cli\u003eRated for roughing and finishing in a single tool, reducing changeover time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders accepting a 1\/4 inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and the control is in an e-stop or lock-out state before inserting or removing the end mill. Use a calibrated collet or shrink-fit holder appropriate for a 1\/4 inch shank diameter to minimize runout. Do not exceed the clamping depth recommended by the toolholder manufacturer, and verify shank engagement before beginning any cut cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.001 to minus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 \/ minus 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.010 \/ minus 0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: 30 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\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\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Corner Radius - Stub and Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36260-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731594445106,"sku":"36260-C3","price":74.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_dec8b676-b2d1-4a93-b78c-ca8c2a2d2b1b.jpg?v=1788732983","url":"https:\/\/voomisupply.com\/products\/harvey-tool-36260-c3-corner-radius-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
