Built from micrograin solid carbide and coated with TiN (Titanium Nitride), it delivers durability and heat resistance in demanding cutting environments. The 1\/4 inch diameter tool features four flutes with an integrated chipbreaker geometry that breaks chips into shorter segments, reducing recutting and heat buildup. With a 3\/4 inch length of cut and 2-1\/2 inch overall length, it is sized for standard roughing passes in tight or open workspaces. Licensed machinists and CNC programmers typically specify this tool for high-volume metal removal before finish passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use on CNC machining centers and manual mills across light manufacturing, tool and die, and job shop environments. The right-hand cutting and right-hand flute direction make it compatible with conventional spindle setups. The centercutting capability allows for direct plunge entry into workpiece material without a pre-drilled hole. The regular length designation and 1\/4 inch shank make it a straightforward drop-in for standard collets and end mill holders in production or prototype work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for wear resistance in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eChipbreaker geometry controls chip length and reduces heat buildup during roughing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for use with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank with tight diameter tolerance for secure, low-runout clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for standard 1\/4 inch collets, end mill holders, and shrink-fit tooling systems used in CNC and manual milling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Use a calibrated torque wrench and appropriate collet nut wrench to seat the shank securely in the holder, avoiding over-tightening that can deform the collet bore. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates wear on carbide tooling.\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 (1\/4 inch)\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: 0.75 inches (3\/4 inch)\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: 0.25 inches (1\/4 inch)\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: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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\u003eChipbreaker\u003c\/strong\u003e: Yes\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2500496\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730365251890,"sku":"2500496","price":260.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7445802-11.jpg?v=1788716105","url":"https:\/\/voomisupply.com\/products\/hertel-2500496-roughing-end-mill-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
