It features a 1\/2 inch cutting diameter, a 5\/8 inch length of cut, and a 4 inch overall length. The APLUS coating provides enhanced lubricity and wear resistance at elevated cutting temperatures. A variable index flute spacing reduces harmonic vibration and chatter, extending tool life and improving surface finish. The reduced neck geometry allows extended reach into deep pockets and contoured features without sacrificing rigidity. This tool is intended for use by machinists and CNC operators working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill belongs to the Helical Solutions End Mills for Steels series and is built specifically for slotting, profiling, and pocketing operations in steel alloys. The 5-flute configuration increases feed rates compared to standard 4-flute tools while maintaining chip evacuation efficiency. The 2.25 inch reach length and reduced neck make it well suited for deep-cavity work where standard-length tools cannot reach. Right-hand cutting and right-hand helical flutes are standard for conventional CNC milling setups. The straight cylindrical shank fits standard ER and end mill holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance in steel milling\u003c\/li\u003e\n  \u003cli\u003eAPLUS coating for extended tool life and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003e5-flute, variable index design reduces chatter and allows higher feed rates\u003c\/li\u003e\n  \u003cli\u003eReduced neck geometry with 2.25 inch reach length for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable for plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand helical flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the Helical Solutions End Mills for Steels - 5 Flute - Square - Variable Pitch - Reduced Neck series.

Secure the straight cylindrical shank to the recommended torque specification of the holder manufacturer using a properly calibrated torque wrench. Inspect the shank and collet bore for chips or contamination before seating the tool. Confirm runout with a dial indicator before beginning production cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\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: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.25 inches (2-1\/4 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\/Finish\u003c\/strong\u003e: APLUS\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 Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: End Mills for Steels - 5 Flute - Square - Variable Pitch - Reduced Neck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.368 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: 50242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51728654926130,"sku":"50242","price":195.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce5f8d3d358f5440e0bf884140db02a9.jpg?v=1788694480","url":"https:\/\/voomisupply.com\/products\/helical-solutions-50242-square-end-mill-1-2-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
