Manufactured from M42 cobalt high-speed steel, this tool delivers the heat and wear resistance required for aggressive roughing passes. It measures 1 inch in diameter with a 2-inch length of cut and a 3\/4-inch shank diameter, giving it the rigidity needed in heavy-duty setups. With 5 flutes and a bright, uncoated finish, it is suited for conventional roughing where chip evacuation and tool life balance are the primary concerns. Machinists and tool-and-die professionals are the primary users of this tool type.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is applied in manual and CNC milling operations where bulk stock removal is the priority before a finishing pass. It is appropriate for use in knee mills, vertical machining centers, and similar setups handling steel, cast iron, and alloy materials. The right-hand cut and right-hand flute direction are standard for conventional milling machine spindle rotation. The regular-length geometry and non-centercutting design mean it is intended for peripheral and side milling, not plunge cutting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction resists heat buildup during aggressive roughing cuts\u003c\/li\u003e\n\u003cli\u003e5-flute design balances chip load and surface contact for efficient material removal\u003c\/li\u003e\n\u003cli\u003e1-inch mill diameter with 2-inch length of cut handles deep roughing passes\u003c\/li\u003e\n\u003cli\u003e3\/4-inch shank diameter provides solid tool holding in standard end mill holders and collets\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a wide range of cutting fluids and dry cutting applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard roughing end mill for use in any milling machine or machining center with a tool holder accepting a 3\/4-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\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. Secure the shank in a properly sized end mill holder or collet to the manufacturer-specified pull-out force for the holder type in use. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and reduces surface quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill 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\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt HSS (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 06821714\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734768976178,"sku":"06821714","price":110.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/742ca76ee82508834752b8f22bfbde32.jpg?v=1788766831","url":"https:\/\/voomisupply.com\/products\/hertel-06821714-roughing-end-mill-1-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
