Ford 17739300A Square End Mill 0.3937 in 4 Flute Carbide","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe M.A. FORD 17739300A is a solid carbide square end mill engineered for high-performance material removal in demanding machining applications. Built on the Series 177 platform, this single-end tool features a 0.3937 inch (10 mm) cutting diameter, a 0.8661 inch (22 mm) length of cut, and a matching 0.3937 inch straight shank for direct collet or end mill holder mounting. The four-flute geometry combined with a variable helix angle of 35 to 38 degrees and variable index spacing reduces harmonic chatter during aggressive cuts. An ALtima AlTiN coating provides thermal protection and extended tool life when cutting ferrous and high-temperature alloy workpieces. Machinists in precision job shops and production environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, and high-temperature alloys in CNC machining center applications. The center-cutting design allows plunge entry as well as conventional peripheral milling, making it effective for slotting, profiling, and pocketing operations. The micrograin carbide substrate supports higher surface footage compared to standard carbide grades, and the right-hand cut with right-hand spiral flute direction is compatible with standard CNC spindle rotation. The overall length of 72 mm accommodates typical toolholder projection requirements without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for wear resistance and edge stability in hard materials\u003c\/li\u003e\n  \u003cli\u003eALtima AlTiN coating for high-heat resistance when cutting steel, stainless steel, cast iron, and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eVariable helix (35 to 38 degrees) and variable index design reduce vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry enables plunge milling, slotting, and profiling in a single tool\u003c\/li\u003e\n  \u003cli\u003eFour flutes with spiral, right-hand flute direction for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSingle-end, straight shank fits standard collet chucks and end mill holders sized for 10 mm or 0.3937 inch bores\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with collet chucks or end mill holders accepting a 0.3937 inch (10 mm) straight shank.

Ensure the shank is fully seated to the minimum insertion depth required by the toolholder manufacturer and torque the collet nut or set screw per the toolholder specification. Inspect the cutting edges and coating for chips or wear before each use, as carbide tooling is brittle and should not be used if edge damage is visible. Follow all applicable shop safety protocols and machine tool manufacturer guidelines during setup and operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8661 inches (22 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 72 mm\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ALtima AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 to 38 degrees (Variable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.058 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0 \/ -0.009 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 177\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 17739300A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51751688962354,"sku":"17739300A","price":142.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86e34b9fd208beb8d8348157be3e035a.jpg?v=1788924106","url":"https:\/\/voomisupply.com\/products\/m-a-ford-17739300a-square-end-mill-0-3937-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
