With a 1\/4 inch cutting diameter and 3\/4 inch length of cut, this tool is built for high-efficiency material removal and surface finishing in demanding CNC machining environments. The APLUS coating improves heat resistance and extends tool life in abrasive cutting conditions. Its right-hand cutting and right-hand helical flute geometry promote chip evacuation and reduce chatter during finish passes. Machinists and tool-and-die professionals working with steel workpieces rely on this geometry for tight-tolerance finishing work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish milling steel and similar ferrous materials in vertical machining centers and CNC mills. It is part of HELICAL SOLUTIONS End Mills for Steels - 5 Flute - Square - Finisher series, making it appropriate for shops running high-RPM finishing passes where surface finish and dimensional accuracy are priorities. The straight cylindrical shank fits standard 1\/4 inch collets and end mill holders. It is a single-end, non-chipbreaker design with no variable helix or variable index, keeping it optimized for consistent finishing cuts rather than general roughing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute helical geometry for improved surface finish and chip evacuation in steel\u003c\/li\u003e\n\u003cli\u003eAPLUS coating for enhanced heat and wear resistance during high-speed finishing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for use with standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the HELICAL SOLUTIONS End Mills for Steels - 5 Flute - Square - Finisher series.

Use a calibrated torque wrench and manufacturer-specified collet or end mill holder to secure the shank. Verify runout with a dial indicator before commencing cuts. A qualified machinist or CNC operator should set speeds, feeds, and depth of cut based on material, machine rigidity, and finishing requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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 Helix\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: End Mills for Steels - 5 Flute - Square - Finisher\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.057 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 05142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51733081817394,"sku":"05142","price":61.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd18179082f640068805e4946e4a2181_18921eba-d7f1-4ffc-b3e5-22279f3408e4.jpg?v=1788751181","url":"https:\/\/voomisupply.com\/products\/helical-solutions-05142-square-end-mill-1-4-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
