Built from M42 cobalt high-speed steel with a TiN (titanium nitride) coating, this tool delivers heat and wear resistance suited to ferrous and high-temperature alloys. It runs a 2-inch cutting diameter with 8 fine-pitch flutes, producing a controlled chip load and a relatively smooth finish for a rougher. The 4-inch length of cut and 1.25-inch shank diameter make it a fit for deep-pocket and heavy-stock-removal applications on vertical mills and machining centers. Right-hand cutting and right-hand flute direction are standard. This tool is not center-cutting.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for shop machinists, tool-and-die tradespeople, and CNC operators working in job-shop or production environments. Typical applications include roughing passes on steel, stainless, and cobalt-alloy workpieces where conventional HSS tooling lacks the thermal stability to maintain edge life. The 8-flute fine-pitch geometry reduces chip load per tooth, allowing higher feed rates while managing vibration in rigid setups. It is well-suited to box-way knee mills and rigid vertical machining centers with adequate spindle horsepower to drive a 2-inch cutter through tough stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated hot hardness and edge retention in tough alloys\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life compared to uncoated cobalt\u003c\/li\u003e\n\u003cli\u003e8 fine-pitch flutes allow higher feed rates and smooth chip evacuation on deep roughing cuts\u003c\/li\u003e\n\u003cli\u003e4-inch length of cut supports deep-pocket milling without excessive tool extension\u003c\/li\u003e\n\u003cli\u003e1.25-inch straight shank fits standard side-lock and milling chuck holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand helix, single-end geometry — not center-cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for milling operations requiring a 2-inch diameter, 1.25-inch shank, single-end cobalt tool with TiN coating.

Power down and lock out the machine spindle before loading or changing tooling. Seat the shank fully in the holder and torque set-screw or collet retention to the holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, as runout on an 8-flute cutter accelerates uneven flute wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6.5 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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 91196956\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753044214066,"sku":"91196956","price":558.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1a352ef14565e330c0b4daa37c8d24f.jpg?v=1788932391","url":"https:\/\/voomisupply.com\/products\/hertel-91196956-roughing-end-mill-2-in-8-flute-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
