Built from M42 cobalt steel, it holds a cutting edge at elevated temperatures generated during aggressive cuts in stainless steel, alloy steel, and hardened materials. The four-flute, spiral design with a 30-degree helix angle balances chip evacuation with surface finish. The mill diameter is 0.6875 inches (11\/16 inches) with a cutting length of 1.625 inches (1-5\/8 inches). It is a single-end, centercutting tool, meaning it can be fed axially into a workpiece for plunge operations as well as conventional peripheral milling.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for manual knee mills, CNC vertical machining centers, and CNC knee mills running fractional-inch tooling. Typical applications include shoulder milling, slotting, and profile milling in job shop, maintenance, and production environments. Right-hand cut and right-hand flute geometry follow the standard convention for the majority of spindle setups in these environments. The uncoated bright finish makes it straightforward to resharpen on a tool and cutter grinder, extending usable life in lower-volume shops where regrinding is practical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction resists heat and wear in ferrous and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eFour flutes with 30-degree helix provide a balance of rigidity, chip clearance, and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation on vertical mills and machining centers\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish simplifies regrinding and tool reconditioning\u003c\/li\u003e\n  \u003cli\u003eRegular length series suits standard reach applications without the deflection risk of extended-reach tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard fractional-inch shank end mill for use in any machine tool spindle, collet chuck, or end mill holder accepting a 5\/8-inch straight shank, including ER collet systems, Weldon-style holders, and similar toolholding setups common on vertical mills and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tooling technician. Power down and lock out the machine spindle before loading or changing tooling. Seat the shank fully into the holder to the recommended engagement depth for the holder type, and torque set screws or clamping nuts per the toolholder manufacturer specifications. Inspect the cutting edges for chipping before each use, and never run a damaged tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/16 inches (0.6875 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\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches (3.75 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\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\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\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 0.29 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: 723-3215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691541365042,"sku":"723-3215","price":75.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74613e9f9fb08cd9113c4835738fcfac.jpg?v=1788286765","url":"https:\/\/voomisupply.com\/products\/value-collection-723-3215-square-end-mill-11-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
