Built from M7 high speed steel with no coating applied, it delivers reliable cutting performance in a range of shop and production environments. The tool features a 7\/8 inch cutting diameter, a 1-1\/2 inch length of cut, and a 1\/2 inch shank diameter for secure toolholder retention. With two flutes and a 30-degree helix angle, it provides efficient chip evacuation during peripheral and slot milling. Licensed machinists and toolroom operators use this style of end mill for profiling, slotting, and step milling on manual mills and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in job shops, toolrooms, and production environments where a standard-length, two-flute square end mill is appropriate. The centercutting geometry allows direct plunge entry into a workpiece without a pre-drilled start hole. Right-hand cut and right-hand flute configuration match conventional milling spindle rotation. The regular-length body and 3-1\/2 inch overall length make it a practical choice for general-depth milling applications within the 1-1\/2 to 2 inch length-of-cut range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and wear resistance in a variety of work materials\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids or dry in softer materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle spiral flute promotes smooth cutting action and chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pilot drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for standard spindle direction compatibility\u003c\/li\u003e\n\u003cli\u003eTwo-flute geometry maximizes chip clearance in slotting and deep-pocket applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 1\/2 inch straight-shank toolholders used in manual milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and power is off before loading or removing end mills from the toolholder. Use a properly sized collet or end mill holder that matches the 1\/2 inch shank diameter to avoid runout and tool pullout under load. Follow shop safety practices and applicable OSHA machine guarding requirements when operating milling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel, Grade M7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCoating\u003c\/strong\u003e: Uncoated\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: 0.504 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: GG99914122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728785932594,"sku":"GG99914122","price":92.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a4434cbf049c9714a78017e3a3fafec.jpg?v=1788696194","url":"https:\/\/voomisupply.com\/products\/hertel-gg99914122-square-end-mill-7-8-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
