Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited for tough ferrous and non-ferrous materials. The 4-flute, right-hand spiral configuration with a 30-degree maximum helix angle promotes efficient chip evacuation during roughing passes. At 0.25 inches in diameter with a 0.375-inch shank, this tool fits standard milling chucks and collets without adapters. The bright, uncoated finish is standard for general-purpose roughing work. Licensed machinists and toolroom professionals are the typical end users for this style of cutter.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations on manual mills, CNC machining centers, and knee mills where a small-diameter, high-performance cutter is required. The regular-length geometry with a 1.25-inch length of cut and 3.0625-inch overall length makes it practical for shallow-to-moderate pocket and slot roughing. The non-centercutting design means it requires a pre-drilled entry point or ramp entry for plunge-style operations. It carries SECO REM445 series designation, indicating its positioning within a defined family of roughing end mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for elevated heat resistance during heavy roughing cuts\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral design at 30-degree maximum helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003e0.25-inch mill diameter with 0.375-inch shank for compatibility with standard toolholding\u003c\/li\u003e\n\u003cli\u003e1.25-inch length of cut accommodates shallow pocket and slot roughing applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suited for general-purpose ferrous and non-ferrous roughing\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry requires pre-drilled or ramped entry — not for direct plunge milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard milling machine toolholders accepting a 0.375-inch shank diameter.

Secure the shank in a clean, properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer's specifications. Confirm spindle direction is set to right-hand rotation before engaging the workpiece. Because this is a non-centercutting end mill, always use a pre-drilled hole or programmed ramp entry rather than a direct axial plunge to avoid tool damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 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 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eMaximum Helix 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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.003 to -0.000 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\u003eSeries\u003c\/strong\u003e: REM445\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 17010361\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558432833842,"sku":"17010361","price":75.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_2fa60a4c-7448-47f4-888f-bf24cc0bf5cb.jpg?v=1786412254","url":"https:\/\/voomisupply.com\/products\/seco-17010361-roughing-end-mill-1-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
