Built from M42 cobalt high-speed steel, it delivers higher heat resistance than standard HSS tooling, making it a practical choice for harder workpiece materials. The cutting diameter is 0.3543 inches (9.00 mm), with a 9\/16-inch length of cut and a 3\/8-inch shank diameter. The two-flute geometry provides good chip clearance and allows higher feed rates in slotting operations. Overall length is 2-5\/16 inches. The uncoated bright finish is standard for general-purpose machining where coating is not required or where regrinding is anticipated.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations in steel, stainless steel, cast iron, and high-temperature alloys. It is appropriate for conventional milling machines, CNC machining centers, and knee mills running at speeds appropriate for cobalt tooling in those materials. The regular-length configuration fits standard toolholding in most shop environments. The right-hand cut and right-hand spiral flute are the conventional orientation for the majority of vertical milling setups. Centercutting capability allows the tool to plunge directly into the workpiece without pre-drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance versus standard HSS\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge cuts without a starter hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation in ferrous materials\u003c\/li\u003e\n\u003cli\u003eTwo-flute configuration provides maximum chip clearance in slotting and pocket milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for applications where regrinding is planned\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, and high-temperature alloy workpieces.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder and verify runout with a dial indicator before beginning the cut. Do not exceed the rated length of cut when side milling, as tool deflection increases significantly beyond the flute length.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3543 inches (9.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 0.5625 inches (9\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.3125 inches (2-5\/16 inches)\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\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\u003eLength Type\u003c\/strong\u003e: Regular\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: 0.02 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: 723-9090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718699811122,"sku":"723-9090","price":28.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09225e6af80e43c450d11b066c37b210.jpg?v=1788555079","url":"https:\/\/voomisupply.com\/products\/value-collection-723-9090-cobalt-square-end-mill-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
