With a 0.031-inch cutting diameter and four helical flutes, this single-end mill delivers both roughing and finishing capability in a compact stub-length geometry. The 30-degree helix angle promotes efficient chip evacuation while the amorphous diamond PVD coating reduces friction and extends tool life when cutting aluminum, copper, brass, and other non-ferrous alloys. Machinists and toolroom operators working in high-precision milling applications will find this tool well-suited for tight-tolerance work in small-scale components.\u003c\/p\u003e\u003cp\u003eThis end mill is built for close-tolerance milling operations where a small-diameter ball profile is required. Its stub-length configuration provides added rigidity, reducing deflection in light-depth passes on CNC machining centers and manual mills. The 0.046-inch length of cut limits its reach intentionally, making it optimal for shallow pocket milling, contouring, and surface finishing on small parts. The 1\/8-inch straight cylindrical shank fits standard collet systems commonly used in high-speed spindles and precision tool holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.031-inch ball end cutting diameter with a 0.0155-inch nose radius for accurate profiling\u003c\/li\u003e\n\u003cli\u003eFour helical flutes with 30-degree helix angle for smooth chip flow in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eAmorphous diamond PVD coating reduces tool wear and improves surface finish on soft metals\u003c\/li\u003e\n\u003cli\u003eStub-length geometry increases rigidity and minimizes deflection at small diameters\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut with right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction throughout for dimensional stability and cutting edge durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and precision manual mills equipped with collet systems accepting a 1\/8-inch straight shank.

Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the end mill from the collet. Use a properly sized, clean collet and torque the collet nut according to the tool holder manufacturer specifications. At this diameter, tool runout must be minimized — verify TIR with an indicator before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0155 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (Reach)\u003c\/strong\u003e: 0.046 inches\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: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: Helical\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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: 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\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: 24631-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51755573805362,"sku":"24631-C4","price":75.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4433bee95fa9e61b241aebcf3e79d011_11689bd6-0d52-48a2-a503-e05251ee9f99.jpg?v=1788956254","url":"https:\/\/voomisupply.com\/products\/harvey-tool-24631-c4-ball-end-mill-0-031in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
