Built from M42 cobalt high-speed steel and coated with TiAlN for heat resistance and extended tool life, this end mill handles demanding cutting conditions across a range of ferrous and non-ferrous materials. The 3\/4 inch diameter cutter features 4 right-hand spiral flutes with a 30-degree maximum helix angle, a stub-length configuration, and a right-hand cutting direction. Center cutting capability allows plunge entry. The tool carries a TiAlN coating that performs well at elevated cutting temperatures without coolant-through capability required.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for use in manual mills and CNC machining centers in job shop, toolroom, and production environments. It is typically selected for roughing passes on steel, stainless, and other tough alloys where rapid stock removal is the priority before a finish pass. The stub flute length of 3\/4 inch keeps the cutter rigid and minimizes deflection under heavy chip loads. The 3\/4 inch shank fits standard ER collet chucks, end mill holders, and Weldon-style tool holders common in trade and industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for elevated hardness and heat resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in dry and semi-dry cutting conditions\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter cutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eStub flute length promotes rigidity and reduces chatter during heavy roughing cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement roughing end mill for use in standard 3\/4 inch end mill holders, ER collet systems, and Weldon-style tool holders.

Ensure the machine spindle is fully powered down and locked out before changing tooling. Verify holder bore cleanliness and shank seating before torquing set screws or collet nuts to holder specifications. Confirm spindle rotation direction matches the right-hand cutting direction of this tool before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.75 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (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\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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: 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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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: REC448\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 17007776\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561609265458,"sku":"17007776","price":118.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e27f3758973f6920ab0b50c3c57489a.jpg?v=1786466447","url":"https:\/\/voomisupply.com\/products\/seco-17007776-roughing-end-mill-3-4-in-4-flute-cobalt-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
