Built with a 3\/16 inch diameter and a 0.025 inch corner radius, this single-end tool produces blended transitions between floor and wall surfaces while reducing stress concentrations at part corners. The 4-flute helical geometry supports both roughing and finishing operations in a single tool. An AlTiN PVD coating adds thermal and wear resistance, extending tool life in abrasive and high-heat cutting environments. Shank diameter matches the mill diameter at 3\/16 inch for direct chuck or collet mounting.\u003c\/p\u003e\n\u003cp\u003eThis end mill is sized for compact work envelopes and small-feature applications commonly encountered in die and mold work, aerospace component machining, and precision part production. The stub length-of-cut configuration improves rigidity, reducing deflection in tight-tolerance passes. The right-hand cutting and right-hand flute direction make it compatible with standard vertical and horizontal CNC milling setups. It is suited for shops running steel, stainless steel, cast iron, composite, and non-ferrous workpieces where corner geometry and surface finish are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides elevated heat and oxidation resistance in ferrous and high-temp alloy cuts\u003c\/li\u003e\n  \u003cli\u003e0.025 inch corner radius blends floor-to-wall transitions and reduces stress risers in finished parts\u003c\/li\u003e\n  \u003cli\u003e4-flute helical design supports both roughing and finishing material removal in a single pass\u003c\/li\u003e\n  \u003cli\u003eStub length-of-cut (0.75 inches) maximizes tool stiffness and minimizes deflection on shallow features\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders and collet chucks accepting a 3\/16 inch straight cylindrical shank.

Seat the shank fully into the collet or toolholder to the recommended gauge depth before tightening to avoid runout and premature tool breakage. Verify runout with a dial indicator after installation, particularly critical at this small diameter. Follow the machine manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.025 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\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\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 Type\u003c\/strong\u003e: Helical\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 End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\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\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\u003eExtended Reach\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.36 inches (L) x 0.32 inches (W) x 0.32 inches (H)\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: 937925-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728816472370,"sku":"937925-C3","price":65.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_472e2c44-8c33-4a92-93bc-40731698f83b.jpg?v=1788696325","url":"https:\/\/voomisupply.com\/products\/harvey-tool-937925-c3-corner-radius-end-mill-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
