With a 3\/32 inch (0.0930 inch) mill diameter and a 0.2790 inch reach length, this single-end tool delivers accurate ball-nose profiling and contouring in tight spaces. The 2-flute, 30-degree right-hand spiral geometry promotes efficient chip evacuation and smooth cutting action. An amorphous diamond PVD coating extends tool life and reduces friction when cutting aluminum, copper, brass, and other non-ferrous workpieces. Machinists and tooling professionals install this end mill on CNC machining centers and manual mills requiring fine detail work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for precision machining operations on non-ferrous metals in both roughing and finishing passes. The stub and standard length classification makes it a practical choice for slotting, profiling, and 3D contouring where tool rigidity matters. Its 1\/8 inch straight-cylindrical shank fits standard ER collets and end mill holders commonly found in CNC mills, engravers, and multi-axis machining centers. The miniature diameter makes it particularly useful in mold and die work, prototype machining, and small-component production where large tools cannot reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/32 inch ball nose diameter with tight mill diameter tolerance of plus 0.0005 \/ minus 0.0005 inches for precise profiling\u003c\/li\u003e\n\u003cli\u003eAmorphous diamond PVD coating optimized for non-ferrous metal cutting, reducing built-up edge and extending tool life\u003c\/li\u003e\n\u003cli\u003e2-flute, 30-degree right-hand helix promotes chip clearance and smooth cutting in slotting and contouring operations\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in miniature end mill applications\u003c\/li\u003e\n\u003cli\u003eSingle-end design with straight-cylindrical 1\/8 inch shank for compatibility with standard collet systems\u003c\/li\u003e\n\u003cli\u003eSuitable for both roughing and finishing material removal in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style miniature ball end mill for use in standard 1\/8 inch collet and end mill holder systems on CNC machining centers and manual mills.

Ensure the spindle is fully stopped and the machine is powered down or in a safe tool-change state before installing or removing the end mill. Seat the 1\/8 inch shank fully into the collet and torque the collet nut per the collet manufacturer specifications. Verify tool runout with a dial indicator before beginning a precision cut, as miniature-diameter end mills are sensitive to concentricity errors.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/32 inch (0.0930 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0465 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length (LOC)\u003c\/strong\u003e: 0.2790 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Amorphous Diamond (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\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 - Stub and Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 74093-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730595381554,"sku":"74093-C4","price":71.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ad5e00ba36685a1749092670edb10b.jpg?v=1788720110","url":"https:\/\/voomisupply.com\/products\/harvey-tool-74093-c4-ball-end-mill-3-32-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
