Ground from M42 cobalt high-speed steel, this single-end tool features four spiral flutes with a 30-degree helix angle, producing efficient chip evacuation and a smooth cut finish. The extra-long 6-inch length of cut makes it well suited for deep-pocket and deep-slot milling work that standard-length end mills cannot reach. It ships bright and uncoated, ready for use in a wide range of ferrous and non-ferrous materials. Licensed machinists and CNC setup technicians are the primary users of this tool class.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for use in vertical machining centers, knee mills, and manual milling machines equipped with an appropriate collet or end-mill holder sized to accept a 1.25-inch shank. The extra-long length of cut suits applications including deep-cavity moldwork, aerospace structural components, die machining, and any operation requiring reach beyond what a standard or long-series end mill provides. The right-hand cutting direction and right-hand flute direction are standard for conventional CNC spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction provides elevated hot hardness compared to standard M2 high-speed steel\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes with 30-degree helix angle promote chip evacuation and reduce cutting forces\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch length of cut enables deep-pocket and deep-slot operations\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge milling as well as peripheral and slot cutting\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish is compatible with most cutting fluids and regrinding services\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 1-1\/4 inch shank diameter for rigid tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end-mill holders, collet chucks, and Weldon-flat set-screw holders accepting a 1-1\/4 inch shank diameter.

Use a properly sized end-mill holder or collet rated for the 1-1\/4 inch shank diameter and torque the retention fastener according to the holder manufacturer specification. Confirm runout with a dial indicator before taking a first cut. Follow your shop safety plan 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: 1.25 inches\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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-3417\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722742104370,"sku":"723-3417","price":296.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4dc9327a3a1bbfba4c6c8a0aa8dcf14.jpg?v=1788595209","url":"https:\/\/voomisupply.com\/products\/value-collection-723-3417-square-end-mill-cobalt-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
