With a 1.40 mm (0.0550 inch) cutting diameter and a 0.1650-inch reach length, this stub-length tool is built for tight-clearance work where a standard-length tool cannot reach. The 4-flute geometry and 30-degree right-hand spiral helix support both roughing and finishing operations in a single tool. An AlTiN PVD coating improves heat resistance and tool life when cutting steel, stainless steel, and cast iron. The 0.1250-inch straight cylindrical shank mounts in standard collet chucks or tool holders.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and milling machines running precision work in steel, stainless steel, and cast iron. The stub standard series designation means the tool prioritizes rigidity over reach, making it a practical choice for contour milling, die work, 3D surface finishing, and slot milling in hard or abrasive materials. It is a single-end tool intended for professional machining environments where dimensional accuracy and surface finish are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.40 mm (0.0550 inch) ball cutting diameter with a 0.0275-inch nose radius\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral design supports roughing and finishing in one tool\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation in ferrous materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating extends tool life in steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eStub-length geometry maximizes rigidity in tight-clearance applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for dimensional stability and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC milling applications targeting steel, stainless steel, and cast iron workpieces.

Ensure the spindle is fully stopped and locked before changing tooling. Seat the 0.1250-inch straight shank fully into the collet or tool holder and torque the retention nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator before commencing a production cut, particularly given the small diameter of this tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.40 mm (0.0550 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: AlTiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.1650 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0275 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5000 inches (1-1\/2 inches)\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 Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\u003ePrimary Workpiece Material\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\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Ball - Stub and Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 74355-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51747478012210,"sku":"74355-C3","price":58.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3129f8eea9ae94caef188c59f90c73c_e7238633-e49b-4008-bc5c-f8fae03a9195.jpg?v=1788881083","url":"https:\/\/voomisupply.com\/products\/harvey-tool-74355-c3-ball-end-mill-1-40mm-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
