It features a 3\/16 inch cutting diameter, a 1 inch length of cut, and a 2.5 inch overall length with a matching 3\/16 inch straight cylindrical shank. The variable pitch (variable index) flute geometry reduces harmonic vibration during cuts, improving surface finish and tool life. The Aplus coating adds wear resistance and heat tolerance, making this end mill well suited for demanding steel milling applications. Installed and operated by machinists and toolroom professionals, this single-end tool runs right-hand cutting with right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill is built for milling steel and similar ferrous alloys in both production and toolroom environments. The 5-flute configuration increases chip load capacity per tooth while the variable pitch design helps suppress chatter in side milling, slotting, and finishing passes. The centercutting capability allows plunge entry directly into material. At 2.5 inches overall length with no extended reach, it is suited for short-overhang setups where rigidity and precision are critical. Typical applications include finish milling, contour milling, and profiling on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16 inch cutting diameter with 1 inch length of cut for precise short-reach milling\u003c\/li\u003e\n\u003cli\u003e5-flute helical geometry for higher feed rates and improved surface finish in steel\u003c\/li\u003e\n\u003cli\u003eVariable pitch (variable index) flute spacing reduces vibration and chatter\u003c\/li\u003e\n\u003cli\u003eAplus coating enhances wear resistance and performance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and heat resistance over HSS alternatives\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting a 3\/16 inch straight cylindrical shank, within the HELICAL SOLUTIONS End Mills for Steels 5 Flute Square Variable Pitch series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists using an appropriate collet or end mill holder rated for the 3\/16 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator after tool installation to confirm proper seating. Follow machine manufacturer guidelines and applicable shop safety standards for speeds, feeds, and workholding 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: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: End Mills for Steels 5 Flute Square Variable Pitch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 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: HELICAL SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 81707\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51753096151346,"sku":"81707","price":50.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c05a2165a410de664ba7f68e184443a_b23c4f56-dc89-486d-a3ba-5c73011ead6c.jpg?v=1788932761","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81707-square-end-mill-3-16in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
