Built with 4 flutes and a variable-pitch (variable index) design, this tool reduces harmonic vibration during aggressive cuts, improving surface finish and extending tool life. It features a 3\/4 inch cutting diameter, a 4 inch length of cut, and a 6.5 inch overall length. The APLUS coating provides enhanced lubricity and heat resistance, making it well suited for dry or near-dry cutting in ferrous materials. This end mill is a single-end, right-hand cut, right-hand flute tool with a straight 3\/4 inch shank and a 35-degree helix angle.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC milling operations targeting steel alloys, stainless steel, and cast iron in both job shop and production environments. The 4 inch length of cut supports deep-pocket and side-wall milling where shorter tools cannot reach. Machinists and CNC programmers working in aerospace, die and mold, and general metalworking will find this tool applicable wherever a rigid, center-cutting, variable-index end mill is needed for ferrous stock removal. The straight shank accepts standard ER collets, hydraulic chucks, and shrink-fit toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable-pitch (variable index) flute geometry reduces chatter and vibration in aggressive steel cuts\u003c\/li\u003e\n  \u003cli\u003eAPLUS coating improves heat resistance and tool life in ferrous and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003e35-degree helix angle promotes efficient chip evacuation in deep-pocket milling\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry as well as peripheral and slot milling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance superior to HSS tooling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers and manual milling machines with toolholding that accepts a 3\/4 inch straight shank.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before loading or changing the tool. Confirm runout at the shank and cutting end with a dial indicator before beginning a cut, as excessive runout accelerates wear and can cause premature tool failure. Follow the toolholder manufacturer torque specifications when tightening collet nuts or chuck bodies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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: APLUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\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: 1.08 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: 82261\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51733141815602,"sku":"82261","price":498.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20d7309ae11a5a70abe83eb1012b67a2_b12417ea-35bd-42d1-89f3-179a17df7cfe.jpg?v=1788751813","url":"https:\/\/voomisupply.com\/products\/helical-solutions-82261-square-end-mill-3-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
