With a 3\/8-inch cutting diameter and a 1-inch length of cut, this end mill handles slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. The Aplus coating reduces friction and improves tool life in abrasive cutting conditions. A variable index flute geometry helps break up harmonic chatter, improving surface finish and extending cutting stability. Machinists and CNC operators in production and job-shop environments rely on this tool for consistent results in steel, stainless, and similar materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills requiring a standard 3\/8-inch straight cylindrical shank. The single-end, center-cutting design allows for plunge entry and direct slot engagement. With a 3-inch overall length and right-hand cutting and flute direction, it fits standard ER and side-lock tool holders commonly used in vertical and horizontal machining center setups. It is appropriate for general-purpose production milling where tool rigidity and coating performance are priorities.\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 materials\u003c\/li\u003e\n  \u003cli\u003eAplus coating reduces friction and extends tool life in abrasive applications\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic chatter during cutting\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable  -  allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand helical flutes for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard ER collets and side-lock holders\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 accepting a 3\/8-inch straight cylindrical shank.

Ensure the spindle is fully powered down and locked before installing or removing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism to the tool holder specification. Confirm runout with a dial indicator before engaging the workpiece.\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 (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\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\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: 0.146 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":67950345158962,"sku":"30337","price":87.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20d7309ae11a5a70abe83eb1012b67a2_bf19bd9f-aa84-4a01-99cd-bad7fe65a8d9.jpg?v=1791714347","url":"https:\/\/voomisupply.com\/products\/helical-solutions-30337-square-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
