Built from M42 cobalt material and finished bright\/uncoated, this single-end mill features a 3\/4 inch cutting diameter, a 1-5\/8 inch length of cut, and a 30-degree right-hand spiral helix. It is centercutting, allowing plunge cuts as well as side and peripheral milling. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual knee mills for ferrous and hard-material stock removal.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose milling in job shop, production, and maintenance machining environments. The 5\/8 inch shank diameter fits standard ER and side-lock toolholders commonly found in vertical and horizontal machining centers. Its regular-length geometry makes it a practical choice for face milling, slotting, profiling, and step milling on steel, stainless steel, cast iron, and similar hard materials where cobalt tooling provides an advantage over standard HSS.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003e4 flutes with right-hand cut and right-hand spiral for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting force and surface finish on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — compatible with cutting fluids and standard coolant systems\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; regular-length series for stable reach-to-rigidity ratio\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 machining applications requiring a 3\/4 inch diameter, 4-flute, single-end cobalt square end mill with a 5\/8 inch shank.

Secure the 5\/8 inch shank firmly in a compatible collet chuck, end mill holder, or Weldon-style side-lock holder before use. Confirm spindle speed and feed rate are appropriate for the workpiece material and depth of cut before engaging the cut. Never exceed the rated length of cut of 1-5\/8 inches to avoid tool deflection or breakage.\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\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches (3.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eChipbreaker\u003c\/strong\u003e: No\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\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 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: 723-3216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718022037810,"sku":"723-3216","price":53.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f3d8272b45d60c2e3329e5d84615674.jpg?v=1788548742","url":"https:\/\/voomisupply.com\/products\/value-collection-723-3216-square-end-mill-3-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
