Built from M42 cobalt high-speed steel and finished with a TiCN coating, it delivers hardness and heat resistance suited for cutting ferrous and non-ferrous metals. The 1.25-inch diameter cutter features 6 flutes in a right-hand cutting, right-hand flute configuration. With a 2-inch length of cut and a 4.5-inch overall length, this regular-length end mill handles standard depth passes in a variety of milling setups. Machinists and toolroom operators select this profile for roughing passes where chip clearance and tool life matter.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical and horizontal milling machines as well as machining centers where roughing passes on steel, stainless, and tough alloys are required. The 6-flute geometry produces a coarser chip than a standard finishing end mill, which helps evacuate material efficiently during heavy cuts. The 1.25-inch shank diameter matches the cutter diameter, allowing direct mounting in standard collet chucks and end mill holders without a step-down adapter. It is a single-end tool, so the entire length of cut is concentrated at one end for maximum rigidity during roughing operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated red hardness and resistance to heat buildup in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTiCN coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e6-flute roughing geometry for efficient chip evacuation and high material removal rates\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard milling machine spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting design — requires a pre-drilled or pre-bored entry point; not suited for plunge milling\u003c\/li\u003e\n  \u003cli\u003eRegular length profile provides rigidity and reduces deflection during aggressive passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for milling machines and machining centers accepting a 1.25-inch shank end mill holder or collet chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder and torque the retention hardware to the holder specification. Because this is a non-centercutting end mill, do not use it for direct plunge entry into solid material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\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: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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\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: 1.9 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 87144754\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734089957682,"sku":"87144754","price":213.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca73f191d481190020b796d45a585753.jpg?v=1788760877","url":"https:\/\/voomisupply.com\/products\/hertel-87144754-roughing-end-mill-1-1-4-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
