The cutting diameter measures 1\/32 inch (0.0310 inches), with a 3-flute spiral geometry and a 30-degree right-hand helix. An AlTiN PVD coating provides thermal resistance and extended tool life in ferrous materials. The long-reach, stub-flute configuration allows access to confined features while maintaining rigidity at this scale. Licensed machinists and CNC operators use this tool for finish and roughing passes in tight pockets, slots, and contoured surfaces.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision CNC machining applications in job shops, tool rooms, and production environments where small-diameter work is required. The stub flute length limits deflection, making it appropriate for milling hardened steels and stainless grades where chatter control is critical. The 1\/8-inch straight-cylindrical shank fits standard collet systems. The single-end design is typical for this diameter class. Applications include die and mold work, medical component machining, and aerospace detail parts requiring tight tolerances at sub-1 mm diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/32 inch (0.0310 inches) ball nose cutting diameter with 0.0155-inch nose radius\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral geometry supports both roughing and finishing operations\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for steel, stainless steel, and cast iron (ISO P, M, K materials)\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eLong-reach design with 0.3120-inch reach length and 0.2660-inch neck length for confined-feature access\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction throughout — no brazed joint at the tip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection within the Harvey Tool Miniature End Mills - Ball - Long Reach, Stub Flute series.

The machine spindle must be fully stopped and the collet nut released before changing tooling. Confirm collet bore matches the 1\/8-inch shank diameter and that runout is within tolerance before engaging the cut, as excessive runout at this diameter will cause premature breakage. Do not exceed manufacturer-recommended feeds and speeds for the workpiece material and coating class.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/32 inch (0.0310 inches \/ 0.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 5\/16 inch (0.3120 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 17\/64 inch (0.2660 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0155 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\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\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Ball - Long Reach, Stub Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 966031-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727159918898,"sku":"966031-C3","price":93.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/881fe2b8691197b644f3b0b6edcb67aa.jpg?v=1788674159","url":"https:\/\/voomisupply.com\/products\/harvey-tool-966031-c3-ball-end-mill-1-32-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
