Ground from solid carbide stock and finished with an APLUS coating, this tool delivers the hardness and lubricity required for aggressive material removal at elevated feed rates. The mill diameter is 0.375 inches with a 1.5-inch length of cut, a 3.5-inch overall length, and a straight 0.375-inch shank. The variable index flute spacing reduces harmonic chatter during high-load cuts, extending tool life and improving surface finish in difficult-to-machine workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for CNC machining centers and mill-turn operations where titanium and high-temp alloy cutting is routine. The variable pitch geometry and APLUS coating make it particularly well-suited for aerospace, medical, and heavy industrial shops running HEM toolpaths at high radial engagement with reduced axial depth. It is also effective in steel and stainless applications where chatter suppression and heat management are priorities. The straight shank fits standard ER and end mill holders without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAPLUS coating provides oxidation resistance and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing suppresses chatter and reduces vibration during HEM toolpaths\u003c\/li\u003e\n  \u003cli\u003e6-flute configuration supports high feed rates with improved chip load per tooth\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand helix, center-cutting geometry for versatile entry and profiling\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; 1.5-inch length of cut with 3.5-inch overall length for reach and stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining applications cutting steel, stainless steel, cast iron, and high-temperature alloys.

Seat the straight shank fully into the holder and torque the retention nut or set screw to the holder manufacturer specification. Inspect the cutting edges and coating for damage before each use. Follow your machine tool builder guidelines and applicable shop safety protocols when programming HEM toolpaths with this cutter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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: APLUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: End Mills for Titanium - 6 Flute - Square - Variable Pitch - For HEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.174 pounds\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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51731992805682,"sku":"84559","price":98.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa9746afe01a9dd06200462449b8e783_250ee7b3-2f93-42b9-994f-650ce7d3e741.jpg?v=1788737765","url":"https:\/\/voomisupply.com\/products\/helical-solutions-84559-square-end-mill-3-8-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
