It features a 1 inch cutting diameter, a 5.25 inch length of cut, and a 9 inch overall length, making it well suited for deep-cavity and extended-reach steel cutting operations. The 40-degree helix angle promotes aggressive chip evacuation and smooth cutting action. An APLUS coating provides thermal resistance and surface hardness to extend tool life in demanding ferrous materials. The variable pitch flute spacing reduces harmonic vibration, improving surface finish and stability at higher feed rates. This tool is installed and operated by machinists and CNC programmers in job shops, production facilities, and toolrooms.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in steel and ferrous alloy machining operations on vertical machining centers, horizontal mills, and CNC milling equipment. It fits the Helical Solutions Steels - 5 Flute - Square - Variable Pitch series, targeting applications where chatter suppression, deep slotting, and high-material-removal rates in steel are required. The 1 inch straight cylindrical shank provides secure clamping in standard end mill holders, collet chucks, and hydraulic toolholders. It is a single-end, right-hand cutting, right-hand flute tool with center-cutting capability, allowing plunge entry when required by the operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch cutting diameter with 5.25 inch length of cut for deep-reach steel milling\u003c\/li\u003e\n  \u003cli\u003e5-flute variable-index design reduces harmonic vibration and chatter during heavy cuts\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces cutting forces in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eAPLUS coating enhances wear resistance and thermal stability for extended tool life in steel\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability compared to HSS tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for steel and ferrous alloy milling operations as part of the Helical Solutions Steels - 5 Flute - Square - Variable Pitch series.

Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before mounting or removing the tool. Seat the shank to the full recommended insertion depth in the toolholder and torque the retention screw to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates wear and reduces surface finish quality on carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: APLUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\u003eFlute Type\u003c\/strong\u003e: Helical Flute\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Steels - 5 Flute - Square - Variable Pitch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.87 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: 88247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51732270743858,"sku":"88247","price":1123.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c05a2165a410de664ba7f68e184443a_c36d3d83-2519-4c95-a8be-7a345a2faedc.jpg?v=1788741059","url":"https:\/\/voomisupply.com\/products\/helical-solutions-88247-square-end-mill-1-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
