With a 0.031-inch cutting diameter and a 3-flute, variable-helix helical flute geometry, it delivers smooth chip evacuation and reduced chatter in tight, detail-critical cuts. The extra-long flute configuration provides a 0.25-inch length of cut, allowing access to features that standard-length tools cannot reach. This end mill is single-end, right-hand cutting, and ships uncoated for direct use or selective coating. It is sized for CNC machining centers and high-speed spindles used by tool-and-die, mold, and precision-parts machinists.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing passes in mold cavities, die details, and complex 3D contoured surfaces where a small-radius ball profile is required. The 0.031-inch diameter targets fine-detail work in hard and ferrous workpiece materials. The 0.125-inch straight-cylindrical shank fits standard collets common to CNC vertical machining centers and micro-milling setups. Its extra-long flute series classification makes it appropriate when reach beyond a stub or standard flute length is needed without moving to a long-reach extension.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.031-inch (0.80 mm) ball cutting diameter with a 0.0155-inch nose radius for precise radius forming\u003c\/li\u003e\n\u003cli\u003eVariable-helix, 3-flute helical geometry reduces harmonic vibration during finishing cuts\u003c\/li\u003e\n\u003cli\u003eExtra-long flute with 0.25-inch length of cut and 0.25-inch reach length for deep-feature access\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard and ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction; single-end configuration\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish; no chipbreaker, no coolant-through, no extended reach body\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining applications targeting hard materials, steel, stainless steel, and cast iron.

Ensure the collet and collet nut are clean and undamaged before seating the 0.125-inch shank; runout at this diameter is critical and should be verified with a test indicator before cutting. Due to the small diameter, avoid side-loading or aggressive plunge entries that exceed the tool's finishing-pass intent. Handle with care — solid carbide at this diameter is brittle and susceptible to edge chipping if dropped or contacted with hard surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.031 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0155 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\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: 34031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51738312900914,"sku":"34031","price":120.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ec74c2d3cdbfbb41c8ebdef92eaf167_2cc2e79d-93f7-4557-9ad3-313662714e24.jpg?v=1788798125","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34031-ball-end-mill-0-031-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
