With a 9\/64-inch (0.1406-inch) cutting diameter, a 13\/32-inch length of cut, and a 3\/16-inch shank diameter, this tool is built for tight-tolerance work on steel, stainless steel, cast iron, and high-temperature alloys. The M42 cobalt construction provides heat and wear resistance beyond standard HSS, making it a reliable choice for harder workpiece materials. It is installed and operated by machinists and tool-and-die professionals on manual mills and CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling operations in job shop, production, and maintenance machining environments. The double-end configuration extends tool life by offering a second usable cutting end, reducing per-cut tooling cost. Its bright uncoated finish makes it well matched for general-purpose steel and stainless cutting where a coating is not required or where re-grinding is anticipated. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces across the supported workpiece materials: steel, stainless steel, cast iron, and high-temperature alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends, extending tool service life\u003c\/li\u003e\n  \u003cli\u003eM42 cobalt material grade offers superior heat resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle supports efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute — standard orientation for most milling setups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose use and compatible with re-grinding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, cast iron, and high-temperature alloys (ISO material codes P, M, K, S).

Confirm the holder is clean, undamaged, and torqued to the machine manufacturer's specification before use. Never exceed the recommended speed and feed rates for the workpiece material and cutting diameter. Inspect both cutting ends before use and replace the tool if chipping, excessive wear, or runout is detected.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/64 inch (0.1406 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13\/32 inch (0.4063 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches (2.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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: Double\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 723-1644\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691206574386,"sku":"723-1644","price":22.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60b579ac02d94e9bf32df1ebff16c355.jpg?v=1788281525","url":"https:\/\/voomisupply.com\/products\/value-collection-723-1644-square-end-mill-9-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
