Built from M42 cobalt high-speed steel with a bright, uncoated finish, this tool handles tough ferrous and non-ferrous materials where heat resistance and edge retention matter. The 5-flute spiral design with a 30-degree maximum helix angle produces a chip-breaking cut pattern that reduces cutting forces and controls vibration during heavy roughing passes. The 1-inch mill diameter paired with a 3\/4-inch shank diameter makes it compatible with standard R8, CAT, and ER collet toolholders common in job shop and production environments. Right-hand cutting and right-hand flute direction are standard for conventional milling setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing operations on machining centers, knee mills, and CNC vertical mills in job shop, toolroom, and production settings. The 1-1\/2-inch length of cut accommodates moderate-depth slotting, peripheral milling, and step milling on steel, stainless, and high-temperature alloys. It is not center-cutting, so plunge entry is not recommended without a pre-drilled pilot hole or ramping entry strategy. Machinists and toolroom operators running roughing programs on general-purpose materials will find this tool fits directly into standard tooling setups without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat resistance and edge toughness in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e5-flute spiral geometry for high feed rates and efficient chip evacuation during roughing\u003c\/li\u003e\n  \u003cli\u003e30-degree maximum helix angle reduces cutting forces and dampens vibration\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for regrinding and use without supplemental coatings\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard milling machine setups\u003c\/li\u003e\n  \u003cli\u003eSeries REM445 single-end configuration with 3\/4-inch shank for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit roughing end mill for standard 3\/4-inch bore toolholders including R8 collets, ER collet chucks, and side-lock holders used on vertical milling machines and CNC machining centers.

Ensure the spindle is fully stopped and the machine is powered down before loading or changing tooling. Seat the 3\/4-inch shank fully into the toolholder and verify runout with a dial indicator before cutting. This tool is not center-cutting and requires a ramping entry or pre-drilled pilot hole for plunge operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7500 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: Bright\/Uncoated\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\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\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\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: 0.53 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: 17010407\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557581226290,"sku":"17010407","price":171.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_9083c7bc-bafc-4ad9-8d5d-56013e637e9f.jpg?v=1786391303","url":"https:\/\/voomisupply.com\/products\/seco-17010407-roughing-end-mill-1-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
