Ford 16303900 Square End Mill 0.039 in 4 Flute Carbide","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe M.A. FORD 16303900 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.0390-inch cutting diameter and a 0.078-inch length of cut, this is a stub-length tool built for rigidity and accuracy in tight workspaces. The 4-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide in a bright, uncoated finish, it maintains sharp edges across a wide range of workpiece materials. A 0.125-inch straight-cylindrical shank and 1.5-inch overall length make it compatible with standard collet and end mill holder setups on CNC and manual milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish milling, slotting, and profiling operations at small feature scales. The Series 163 designation covers a range of small-diameter carbide tools intended for precision work in materials classified under workpiece material codes H, K, M, N, P, and S, which include hardened steels, cast irons, stainless steels, non-ferrous metals, steel alloys, and high-temperature alloys. It is appropriate for use in tool rooms, production shops, and precision manufacturing environments where small-diameter accuracy is critical. A licensed machinist or CNC operator typically installs and runs this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0390-inch cutting diameter with plus or minus 0.0005-inch diameter tolerance for tight dimensional control\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree right-hand spiral for efficient chip flow and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eStub length type with 0.078-inch length of cut maximizes tool rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with or without cutting fluid across compatible material types\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with workpiece material codes H, K, M, N, P, and S as designated by the manufacturer, covering hardened steels, cast irons, stainless steels, non-ferrous metals, steel alloys, and high-temperature alloys.

Secure the 0.125-inch shank fully in a collet or end mill holder to the recommended engagement depth before tightening. Confirm tool runout with a dial indicator before commencing cuts, as runout is especially critical at this diameter. Never exceed the manufacturer-recommended feed and speed parameters for the material being machined, and inspect the cutting edges for chipping or wear between operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.0390 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.078 inches (5\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 163\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0092 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: M.A. FORD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16303900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51739734507826,"sku":"16303900","price":58.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c29cb2f38f637af168a34e92155edd0_d2433628-2da0-43d3-903a-35e1ecd50b84.jpg?v=1788818340","url":"https:\/\/voomisupply.com\/products\/m-a-ford-16303900-square-end-mill-0-039-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
