With a 5\/64 inch (0.0780 inch) mill diameter and a 13\/32 inch length of cut, this tool is built for miniature, long-flute applications where reach and accuracy are critical. The 3-flute geometry with a variable helix angle of 20 degrees promotes chip evacuation and reduces chatter during finishing operations. Machining professionals and tool-and-die shops use this end mill for tight-tolerance work where a standard-length tool cannot access the required depth.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing operations in hard materials and secondary workpiece materials including steel, stainless steel, and cast iron. Its long-flute, miniature profile makes it appropriate for deep-cavity milling, contour work, and intricate part features on CNC machining centers. The bright, uncoated finish is compatible with a range of cutting fluids and is typical for carbide tooling used in precision finishing passes where surface finish quality is the priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard material applications\u003c\/li\u003e\n\u003cli\u003eVariable helix angle (20 degrees) reduces vibration and improves surface finish\u003c\/li\u003e\n\u003cli\u003e3-flute, spiral flute design optimized for finishing material removal\u003c\/li\u003e\n\u003cli\u003eLong-flute geometry provides extended reach for deep-cavity and contour milling\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h6 tolerance for consistent tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills with a 1\/8 inch straight-cylindrical collet or tool holder.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1\/8 inch shank fully into the collet and torque the collet nut according to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cutting pass, as runout is especially critical at this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.0780 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13\/32 inch (0.4060 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inch\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: 20 degrees (Variable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0390 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eEnd Type\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: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Ball - Long Flute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 32278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51744851853618,"sku":"32278","price":61.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05870c3f1a623f40090bd033d5557769_7771f7aa-43ab-4a70-80ed-239227e15788.jpg?v=1788861549","url":"https:\/\/voomisupply.com\/products\/harvey-tool-32278-ball-end-mill-5-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
