Built from solid carbide and coated with Tplus for enhanced wear resistance and heat tolerance, this tool features a 1\/8 inch diameter cutting edge with a 0.0100 inch corner radius, 5 variable-pitch flutes, and an integrated chipbreaker geometry. The variable pitch flute spacing reduces harmonic vibration during cut, and the chipbreaker promotes efficient chip evacuation in tough, stringy materials. Right-hand cutting and right-hand flute direction are standard on this configuration.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for precision milling operations in stainless steel, nickel alloys, titanium, and other difficult-to-machine high-temperature materials. With a 3\/4 inch length of cut and a 2-1\/2 inch overall length, it fits standard CNC machining center setups and manual mills where a 1\/8 inch straight-cylindrical shank is appropriate. The centercutting design allows plunge entry. Typical applications include slotting, profiling, and contouring in aerospace, medical, and industrial component machining where material work-hardening and heat generation are primary concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in demanding alloys\u003c\/li\u003e\n\u003cli\u003eTplus coating extends tool life in stainless steel and high-temp materials\u003c\/li\u003e\n\u003cli\u003e5-flute variable-pitch design reduces chatter and harmonic vibration\u003c\/li\u003e\n\u003cli\u003eIntegrated chipbreaker improves chip evacuation in stringy, tough materials\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pilot drilling\u003c\/li\u003e\n\u003cli\u003e0.0100 inch corner radius protects cutting edge and reduces stress concentrations at part corners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 1\/8 inch straight-cylindrical shank.

Ensure the spindle is fully powered down and the machine is in a safe state before tooling changes. Use a properly sized collet or end mill holder matched to the 1\/8 inch shank diameter to ensure concentricity and minimize runout. Verify tool projection and stick-out against the programmed depth of cut and workpiece fixturing before initiating any cutting cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\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: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: Tplus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Pitch\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: Stainless and High Temp - 5 Flute - Corner Radius - Variable Pitch - Chipbreaker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 88509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51744848609586,"sku":"88509","price":74.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7552614f1d2ff4903c1270ed9632790c.jpg?v=1788861503","url":"https:\/\/voomisupply.com\/products\/helical-solutions-88509-corner-radius-end-mill-1-8-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
