With a 0.0315 inch (0.80 mm) mill diameter and a 2-flute helical geometry, this single-end tool delivers clean material removal in both roughing and finishing operations. The 28-degree medium helix angle promotes chip evacuation while maintaining edge stability at small diameters. An HXT PVD coating extends tool life by increasing surface hardness and thermal resistance. The micrograin carbide substrate supports tight tolerances and consistent performance at depth.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for high-precision machining applications where small-diameter tooling is required, including die and mold work, micro-feature machining, and detail work in hard material grades. The extended-reach configuration, with a 1.60 mm reach length and 0.76 mm neck diameter, allows access to narrow slots and recessed features without interference. The straight-cylindrical shank measures 6.00 mm in diameter with an h5 tolerance, making it compatible with standard collet and shrink-fit toolholders. This tool is intended for use by machinists and toolroom professionals working on CNC milling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0315 inch (0.80 mm) ball diameter with a nose radius of 0.40 mm for precise contour milling\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and dimensional stability at small diameters\u003c\/li\u003e\n  \u003cli\u003eHXT PVD coating rated for hard material applications, improving wear resistance and heat management\u003c\/li\u003e\n  \u003cli\u003eExtended-reach design with 1.60 mm reach length and 0.76 mm neck diameter for recessed feature access\u003c\/li\u003e\n  \u003cli\u003e28-degree medium helix, right-hand cut, right-hand flute for effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 50.00 mm overall length and 6.00 mm straight-cylindrical shank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC milling applications targeting hard material workpieces (material code H).

Maximum TIR is 0.01 mm — verify runout at setup before cutting. Coolant-through is not supported; external coolant or air blast should be directed at the cutting zone. Inspect the cutting edge under magnification before each use, as small-diameter carbide tools are susceptible to chipping if mishandled or dropped.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter (mm)\u003c\/strong\u003e: 0.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 28 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\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\u003eCoating\u003c\/strong\u003e: HXT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.00 \/ -0.01 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.01 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (Code H)\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: JMB112\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03204984\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562613768498,"sku":"03204984","price":135.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c529bf0af9a361a1aae1ae443dc2a32.jpg?v=1786480802","url":"https:\/\/voomisupply.com\/products\/seco-03204984-ball-end-mill-0-0315-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
