Built from M42 cobalt high-speed steel with a TiCN coating, this tool delivers improved wear resistance and heat tolerance compared to standard HSS tooling. The 3\/8 inch diameter cutter features 3 spiral flutes in a high-helix, right-hand configuration with a 36-degree maximum helix angle, promoting efficient chip evacuation and reduced cutting forces. The TiCN finish extends tool life in abrasive materials. It is centercutting, allowing plunge entry into workpieces without a pilot hole.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is suited for use in manual mills, CNC machining centers, and knee mills in job shop, tool room, and production environments. It is commonly applied to steel, stainless steel, and high-temperature alloys where high-speed steel tooling would wear prematurely. With a 3\/4 inch length of cut and 2-1\/2 inch overall length, it fits standard 3\/8 inch collets and end mill holders. It is a regular-length tool appropriate for general-depth pocketing, slotting, and peripheral milling passes where a roughing profile is needed before finishing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating extends tool life in abrasive and hardened materials\u003c\/li\u003e\n  \u003cli\u003e3 spiral flutes with high-helix geometry at 36-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC and manual mill spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eSeries RHC752 regular-length format fits 3\/8 inch collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fit for machine tools accepting 3\/8 inch shank end mill holders or collets in manual or CNC milling setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and tooling technicians. The spindle must be fully powered down and locked before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention nut to the machine manufacturer's specification. Confirm runout with a dial indicator before first cut, as excessive runout accelerates edge wear on cobalt tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees maximum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RHC752\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.005 to -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.062 to -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17013549\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564226609458,"sku":"17013549","price":75.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8a384db01393a6bcc39307fcbf2499d_a1466fa0-3d34-44ee-b2dd-a65613a01f6d.jpg?v=1786514631","url":"https:\/\/voomisupply.com\/products\/seco-17013549-roughing-end-mill-3-8-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
