Built from M42 cobalt high-speed steel and coated with TiAlN for heat and wear resistance, this tool handles tough ferrous and stainless alloys where standard HSS cutters fall short. It carries a 3\/4-inch mill diameter, a 3-inch length of cut, and a 5-1\/4-inch overall length. The 4-flute, right-hand spiral geometry with a 30-degree maximum helix angle produces the chip-breaking action needed to reduce cutting forces and prevent recutting in deep-cavity passes. This is a shop-floor tool installed and operated by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing passes on vertical and horizontal milling machines, CNC machining centers, and manual knee mills. The TiAlN coating extends tool life in dry or near-dry cutting conditions where heat generation is high. The regular-length profile and 3\/4-inch shank make it compatible with standard ER, Weldon, and milling chuck toolholders. It is appropriate for slotting, peripheral milling, and pocketing operations in steel, alloy steel, and other medium-to-hard materials. No coolant-through capability means this tool is intended for external coolant or dry cutting setups only.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt substrate provides superior hot hardness compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves oxidation resistance and extends tool life in high-temperature cuts\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral geometry promotes efficient chip evacuation during roughing\u003c\/li\u003e\n  \u003cli\u003e30-degree maximum helix angle balances cutting force and surface finish on rough passes\u003c\/li\u003e\n  \u003cli\u003e3-inch length of cut accommodates deep-cavity and long-reach roughing applications\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; not center-cutting — requires a pre-drilled entry point for plunge operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style roughing end mill in the SECO REM445 series, suitable for use in standard 3\/4-inch toolholders on CNC and manual milling platforms.

Secure the shank fully within the toolholder to the recommended engagement depth before tightening — never grip on the fluted section. Verify runout with a dial indicator after clamping. This tool is not center-cutting; do not use for direct plunge entry without a pre-drilled or pre-milled starting point. Disengage machine power and follow lockout\/tagout procedures before changing 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\/4 inch (0.7500 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)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches (3.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\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\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\u003eCenter Cutting\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.003 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\u003eSeries\u003c\/strong\u003e: REM445\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17014845\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560558821682,"sku":"17014845","price":154.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_2404a757-88aa-4477-91ed-6a8384d5564c.jpg?v=1786453807","url":"https:\/\/voomisupply.com\/products\/seco-17014845-roughing-end-mill-3-4-in-4-flute-cobalt-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
