Machined from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to ferrous metals and harder workpiece materials. The 1-inch diameter, 4-flute geometry with a 60-degree helix angle provides efficient chip evacuation and smooth surface finishes in a single setup. The bright, uncoated finish keeps the tool ready for use as supplied. At 0.9 pounds, this is a solid, full-size tool intended for installation in machining centers, knee mills, and manual milling machines by machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in job shop, production, and toolroom environments where both roughing passes and finish milling are required on the same tool. The 2-inch length of cut and 4.5-inch overall length make it appropriate for standard-depth pockets, slots, and profile cuts in steel, stainless, cast iron, and similar materials. The Weldon flat shank provides positive drive retention in side-lock toolholders, reducing slip under heavy cutting loads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003e60-degree helix angle promotes efficient chip flow and smooth cutting action\u003c\/li\u003e\n\u003cli\u003e4-flute, square-end geometry supports both roughing and finishing in one tool\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank ensures positive drive engagement in side-lock holders\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1-inch bore side-lock or Weldon flat toolholders on vertical and horizontal milling machines.

Power down and lock out the milling machine before inserting or removing the tool from the toolholder. Ensure the Weldon flat is properly aligned with the set screw in the side-lock holder and torque the set screw per the toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000\/+0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 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: C4SRH-6408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713074004274,"sku":"C4SRH-6408","price":185.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33887e5dbebb5f234140b813840281a7.jpg?v=1788490942","url":"https:\/\/voomisupply.com\/products\/value-collection-c4srh-6408-1-in-4-flute-cobalt-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
