Built from solid carbide with an AlTiN (aluminum titanium nitride) PVD coating, it handles steel, stainless steel, cast iron, non-ferrous metals, and composites. The tool measures 0.1406 inches in diameter with a 0.015 inch corner radius, a 3-inch overall length, and a 3\/4-inch reach length that provides extended access into deep pockets and narrow features. Three right-hand spiral flutes with a 30-degree helix angle provide efficient chip evacuation for both roughing and finishing operations. It is center-cutting and runs in standard toolholders used by CNC machinists and precision milling specialists.\u003c\/p\u003e\n\u003cp\u003eThis end mill belongs to the Harvey Tool Miniature End Mills - Corner Radius - Long Reach, Stub Flute series. It is suited for milling operations that require extended reach into deep cavities while maintaining a small cutting diameter. The stub flute geometry reduces deflection in long-reach applications. Primary workpiece materials include steel (P), stainless steel (M), cast iron (K), non-ferrous metal (N), and composites. The straight-cylindrical shank diameter of 3\/16 inches fits standard collets and toolholders used in CNC machining centers and high-speed spindle setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating extends tool life in high-temperature cutting environments\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces stress concentrations at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 3\/4-inch reach length and 3-inch overall length for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting, right-hand flute direction enables plunge entry and full ramping operations\u003c\/li\u003e\n  \u003cli\u003eNormal pitch, three-flute design supports both roughing and finishing material removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard CNC toolholders and collet systems accepting a 3\/16-inch straight-cylindrical shank.

Confirm runout and tool stick-out before engaging the cut, as extended-reach tools are more sensitive to deflection at higher overhangs. Ensure the spindle and axis drives are fully stopped and the machine is in a safe state before loading or removing the tool. Follow the machine tool manufacturer and shop SOP for cutter speed, feed rate, and depth-of-cut recommendations specific 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: 0.1406 inches (9\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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\u003eLength of Cut\u003c\/strong\u003e: 0.126 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0100 \/ -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 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 Type\u003c\/strong\u003e: Spiral, 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\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 42809-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51739293516082,"sku":"42809-C3","price":88.21,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6aa536101e5e90c004fe39f0183f1c97_b42dcf1a-f6ff-46b4-bdd3-5b5478072855.jpg?v=1788812778","url":"https:\/\/voomisupply.com\/products\/harvey-tool-42809-c3-corner-radius-end-mill-0-1406in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
