It features a 3\/8 inch diameter, a 0.05 inch corner radius, and four right-hand helical flutes at a 30-degree helix angle. The AlTiN (aluminum titanium nitride) PVD coating provides elevated heat resistance and extended tool life in ferrous and difficult-to-machine materials. This is a single-end, centercutting tool capable of both roughing and finishing operations in one setup. Licensed machinists and CNC operators will recognize this as a standard miniature stub\/standard series tool suited for tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills where corner radius profiles are required to reduce stress concentrations at the base of milled features. Its short flute length and stub geometry make it well suited for rigid setups with minimal deflection. Applicable workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, and composites, covering ISO material groups P, M, K, N, and O. It is appropriate for production shops and toolrooms working with precision mold, die, and general component work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for high-temperature performance and extended cutting life\u003c\/li\u003e\n  \u003cli\u003e0.05 inch corner radius reduces stress risers and improves surface finish at feature transitions\u003c\/li\u003e\n  \u003cli\u003eFour right-hand helical flutes at 30 degrees support both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 3\/8 inch shank fits standard ER and side-lock toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders accepting a 3\/8 inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and the tool is secured in a properly sized collet or toolholder before tightening. Verify runout at the cutting diameter before engaging the workpiece, as excessive runout will accelerate edge wear on carbide tooling. Follow the toolholder manufacturer torque guidelines when tightening collet nuts or set screws.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.0010 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0020 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: 1.25 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: +0.0100 to -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 915250-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51737085575474,"sku":"915250-C3","price":102.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_a87895bc-7e4e-4b07-ade1-491fa5a495d5.jpg?v=1788784065","url":"https:\/\/voomisupply.com\/products\/harvey-tool-915250-c3-corner-radius-end-mill-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
