With a 3\/8 inch cutting diameter and 4-flute helical geometry, this single-end tool delivers clean square shoulders and efficient chip evacuation at aggressive feed rates. The APLUS coating provides enhanced hardness and heat resistance, extending tool life in abrasive and high-temperature cutting conditions. A variable index flute spacing reduces harmonic vibration during cut, improving surface finish and dimensional accuracy. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills where consistent edge integrity is critical.\u003c\/p\u003e\u003cp\u003eThis end mill suits a wide range of material removal tasks in job shop, production, and maintenance machining environments. It is well suited for slotting, peripheral milling, and profiling operations on ferrous and non-ferrous workpiece materials. The 1\/2 inch length of cut and 2 inch overall length make it practical for shallow-to-moderate depth passes. The straight-cylindrical shank fits standard ER collet chucks, end mill holders, and milling machine spindles accepting 3\/8 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch cutting diameter with 1\/2 inch length of cut for controlled material removal\u003c\/li\u003e\n\u003cli\u003e4-flute helical right-hand flute configuration for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eAPLUS coating increases surface hardness and thermal resistance for longer tool life\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and improves finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for broad holder compatibility\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 3\/8 inch straight-cylindrical shank end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware according to the holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 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\/Finish\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eVariable Helix\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.101 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: 30317\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51730258526514,"sku":"30317","price":78.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20d7309ae11a5a70abe83eb1012b67a2_2d8de231-88b5-4cee-a5b5-a1bc33a67fe7.jpg?v=1788714227","url":"https:\/\/voomisupply.com\/products\/helical-solutions-30317-square-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
