It features a 0.025-inch cutting diameter with a 0.0125-inch nose radius, a 3-flute helical geometry, and a solid carbide construction with an AlTiN (aluminum titanium nitride) PVD coating. The long-reach, stub-flute configuration allows the tool to access deep or confined features while maintaining rigidity. With a 30-degree helix angle and right-hand cutting and flute direction, it is suited for both roughing and finishing operations in ferrous and abrasion-resistant workpiece materials. Machinists and CNC tooling specialists use this tool for tight-tolerance contouring and profiling work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for miniature and micro-scale milling applications where cutter diameter, reach, and runout tolerance are critical. The 0.025-inch diameter and 0.037-inch length of cut make it appropriate for fine detail work, small radius features, and complex 3D surface profiles. The stub flute length paired with extended reach geometry helps reduce deflection when working in slots, pockets, or contoured surfaces at depth. It is a single-end tool with a straight cylindrical 0.125-inch shank, fitting standard ER collet systems and miniature toolholders commonly used in precision CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.025-inch ball nose diameter with 0.0125-inch nose radius for fine detail contouring\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3-flute helical design supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eLong-reach, stub-flute geometry allows access to deep features while limiting deflection\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction with 30-degree helix angle for rigidity and smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting and flute direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining applications on steel, stainless steel, and cast iron workpieces.

Always verify spindle runout before running miniature-diameter end mills, as excess runout accelerates tool wear and breakage at small diameters. Follow machine tool manufacturer guidelines for feed rate, depth of cut, and spindle speed when working with sub-0.030-inch diameter tooling. Do not exceed rated cutting parameters for the workpiece material designation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.037 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.213 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\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\u003eExtended Reach\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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: 966025-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51735634542898,"sku":"966025-C3","price":93.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/881fe2b8691197b644f3b0b6edcb67aa_439cdc03-30e2-4c2a-86a1-409aad748bb8.jpg?v=1788773387","url":"https:\/\/voomisupply.com\/products\/harvey-tool-966025-c3-ball-end-mill-0-025-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
