Built from M42 cobalt steel, this single-end mill features four spiral flutes with a 30-degree helix angle, right-hand cut, and right-hand flute orientation. The centercutting geometry allows plunge cutting in addition to peripheral and slot milling. With a 7\/8 inch cutting diameter and 1-7\/8 inch length of cut, this tool handles full-slot, side milling, and profiling work across a range of ferrous and non-ferrous workpieces. It arrives uncoated in a bright finish.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose machining in job shops, tool rooms, and maintenance environments. The regular-length body and 7\/8 inch shank diameter make it compatible with standard collet chucks and end mill holders commonly found on vertical machining centers and manual knee mills. It is well suited for steel, stainless steel, cast iron, and harder materials where cobalt-grade tooling is specified. The uncoated bright finish keeps regrinding straightforward when the tool reaches the end of its service life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance versus standard HSS\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish simplifies regrinding and reconditioning\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with regular length body for rigid setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock end mill for use in standard 7\/8 inch collet chucks and end mill holders on vertical mills, knee mills, and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the collet or holder is clean and free of chips before seating the shank. Verify runout with a dial indicator after clamping to confirm concentricity before cutting. Follow the machine tool manufacturer's recommendations for speed and feed based on workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches (1.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches (4.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCCC-C-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-3219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715355672882,"sku":"723-3219","price":60.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/493d31ea6b97ebf32479fd93a2660476.jpg?v=1788512627","url":"https:\/\/voomisupply.com\/products\/value-collection-723-3219-square-end-mill-7-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
