Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to tough ferrous and non-ferrous workpiece materials. The 5-flute geometry produces a wave-pattern cutting edge that breaks up chips and reduces chatter during heavy hogging cuts. With a 1 inch cutting diameter, a 6 inch length of cut, and an 8.5 inch overall length, this tool handles deep-reach roughing passes where shorter tooling cannot reach. The bright, uncoated finish is standard for cobalt tooling used in a wide range of shop applications. Licensed machinists and tooling specialists are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations on machining centers, knee mills, and manual or CNC vertical mills. Its 1 inch shank diameter seats directly in standard R8, CAT, BT, or HSK toolholders of the appropriate bore. The extended 6 inch length of cut makes it well matched to deep-pocket milling, slotting in thick plate, and profiling tall workpiece features where a standard-length end mill would bottom out in the holder before reaching depth. Right-hand cutting direction and right-hand flute spiral are standard for conventional spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e5-flute roughing geometry reduces cutting forces and breaks chips for efficient evacuation\u003c\/li\u003e\n\u003cli\u003e1 inch cutting diameter with matching 1 inch shank diameter for rigid, concentric seating\u003c\/li\u003e\n\u003cli\u003e6 inch length of cut enables deep-pocket and tall-feature milling passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand helix — compatible with standard CNC and manual mill spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating interaction with cutting fluids or workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-geometry roughing end mill for use in any milling machine or machining center that accepts a 1 inch straight shank toolholder. No specific OEM machine or system compatibility was stated in the product data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the machine control in a safe, locked-out state per OSHA lockout\/tagout requirements. Use a calibrated torque wrench and manufacturer-specified drawbar or collet nut torque when seating the shank — do not overtighten by feel alone. Confirm tool runout with a dial indicator after tightening; excessive runout on a roughing end mill accelerates flute chipping and shortens tool life. End mills are not center-cutting — do not plunge axially into solid material; ramp or helical entry is required for pocket starts.\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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\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\u003eWeight\u003c\/strong\u003e: 0.504 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: 91197236\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734970040626,"sku":"91197236","price":191.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/824fbcb5cd16bcd92c0bfd4f29162c7f.jpg?v=1788768710","url":"https:\/\/voomisupply.com\/products\/hertel-91197236-roughing-end-mill-1-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
