It features a 0.25 inch diameter with a 0.01 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in interrupted cuts. The 4-flute, single-end geometry with a short flute length of 0.255 inches and 2.5 inch overall length suits a straight cylindrical shank setup in standard end mill toolholders. Variable index and variable helix geometry help suppress chatter during both roughing and finishing passes. Machining professionals and tool-and-die shops rely on this configuration for high-accuracy work in steel, stainless steel, and superalloy components.\u003c\/p\u003e\n\u003cp\u003eThis end mill targets applications in steel, stainless steel, superalloys, titanium, and cast iron  -  material groups that demand a submicron carbide substrate and a rigid, short-reach tool. It is suited for vertical machining centers and CNC mills running right-hand cutting with right-hand flute direction. The centercutting design allows plunge entry where required, adding versatility in slotting and pocketing operations. The straight-cylindrical shank with h6 tolerance is compatible with standard collet chucks and hydraulic toolholders used in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.01 inch corner radius reduces edge chipping and improves surface finish on hardened steels and superalloys\u003c\/li\u003e\n  \u003cli\u003eVariable index and variable helix geometry actively reduce harmonic chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide substrate provides hardness and wear resistance required for stainless steel and titanium\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry for slotting and pocketing without a pre-drilled pilot\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 tolerance ensures consistent runout in precision collet and hydraulic holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flutes with normal pitch  -  compatible with standard CNC toolpath conventions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill toolholders. Primary workpiece materials include steel, stainless steel, superalloys, and titanium; secondary workpiece material is cast iron. Shank diameter of 0.25 inches fits 1\/4 inch collet systems and toolholders rated for straight-cylindrical shanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians following shop-standard tool-change procedures. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Confirm runout with a dial indicator after clamping, as h6 shank tolerance is designed for tight collet or hydraulic holder fits. Follow your machine tool manufacturer guidelines for speeds, feeds, and depth-of-cut recommendations appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.255 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FX3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.39 pounds\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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 310097\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51959427072306,"sku":"310097","price":76.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cc0649054787bc4005d2d190b2f5254_cdb338a5-2931-4e50-8786-4f214a4af755.jpg?v=1789945686","url":"https:\/\/voomisupply.com\/products\/gws-310097-corner-radius-end-mill-0-25in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
