It carries a 3\/4 inch cutting diameter, a 3 inch length of cut, and a 5-1\/4 inch overall length, placing it in the long-series category. The 42-degree spiral flute geometry promotes aggressive chip evacuation while the TiN finish extends surface hardness and wear resistance compared to uncoated HSS tooling. With a 3\/4 inch straight shank, this end mill seats in standard ER and side-lock toolholders found on most knee mills, bed mills, and CNC machining centers. Installation and operation are handled by machinists and tool-and-die professionals working in general machining, mold work, and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, peripheral milling, and plunge operations in ferrous and non-ferrous materials where a long reach is required to clear fixtures or machine deep pockets. The centercutting design allows direct plunge entry without a pre-drilled hole, which simplifies setup on manual and CNC equipment. Right-hand cut and right-hand flute configuration is the industry standard for conventional and climb milling on vertical spindles. The long series length makes it well-suited for deep-cavity work in mold bases, die blocks, and structural weldments where a standard-length tool would not reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction provides good toughness and resistance to chipping under interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction for extended tool life versus bare HSS\u003c\/li\u003e\n  \u003cli\u003e42-degree helix angle promotes efficient chip flow and reduces cutting forces in ductile materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eLong-series length (3 inch LOC, 5-1\/4 inch OAL) enables deep-pocket and extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute — compatible with standard vertical mill spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for any machine spindle accepting a 3\/4 inch straight shank end mill, including vertical knee mills, bed mills, and CNC machining centers equipped with ER collet chucks, Weldon side-lock holders, or equivalent toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEnd mills of this type are installed and changed by qualified machinists or toolroom personnel. Always de-energize and lock out the machine spindle before inserting or removing cutting tools. Seat the shank fully into the toolholder to the recommended engagement depth and torque the drawbar or set screw per the toolholder manufacturer specifications. Inspect the collet or holder bore for chips and wear before each setup, as a dirty or worn bore will compromise runout and reduce tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches (3.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 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: GH071048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748445749554,"sku":"GH071048","price":109.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9a630adcd44126896777ace41fc45e5.jpg?v=1788893860","url":"https:\/\/voomisupply.com\/products\/hertel-gh071048-square-end-mill-3-4-inch-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
