It carries a 0.312-inch mill diameter, a 0.03-inch corner radius, and three right-hand spiral flutes with a variable helix geometry. The variable helix design, part of the ECAI-H3-CF Chatter Free series, reduces harmonic vibration during aggressive cuts and helps maintain surface finish quality. The end mill measures 2.5 inches in overall length with a 0.5-inch length of cut and is center-cutting, allowing plunge entry. It ships bright and uncoated, suited for applications where coating would alter tolerances on close-tolerance workpieces.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for machining non-ferrous metals including aluminum alloys, copper alloys, and similar materials. The extended reach configuration, with a 0.9-inch reach length, makes it suitable for pocketing, contouring, and slotting operations where clearance to the workpiece is limited. The single-end, short-series design fits standard straight-bore toolholders. The coarse pitch and variable helix make it particularly effective for high-speed and high-feed strategies common in CNC milling environments. It is intended for use by machinists in job shops, production machining, and tool rooms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix, Chatter Free series geometry reduces vibration during heavy cuts\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003e0.03-inch corner radius reduces stress concentration at the cutting edge\u003c\/li\u003e\n\u003cli\u003eExtended reach at 0.9 inches accommodates deep pocket and contour work\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eFine grain solid carbide construction for edge retention in non-ferrous applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore cylindrical toolholders.

Confirm toolholder bore compatibility with the 0.312-inch shank diameter before mounting. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Do not exceed the tool's rated length of cut when programming depth of pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Variable Helix\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECAI-H3-CF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.637 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5622931\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51742251254066,"sku":"5622931","price":97.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23d9e81d368e2cdbcaf571bdcb4c3d65_642dea9b-d45b-4678-8576-5130c0001e3c.jpg?v=1788836205","url":"https:\/\/voomisupply.com\/products\/iscar-5622931-corner-radius-end-mill-0-312in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
