It features a 3\/4 inch cutting diameter with a 1-1\/2 inch length of cut, a 3\/4 inch shank diameter, and a 4 inch overall length. The three-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and stable cutting performance. This is an uncoated, centercutting end mill, meaning it can be used for plunge cutting as well as peripheral and slot milling. It is installed and applied by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and contouring operations on ferrous and non-ferrous materials in both manual and CNC milling setups. The C1-301 series regular-length geometry makes it a practical choice for general-purpose work where rigidity and tool reach are balanced. The solid carbide construction at material grade C2 provides hardness and wear resistance appropriate for demanding cutting conditions. Typical applications include milling steel, aluminum, and similar machinable alloys in light to medium-duty production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction at material grade C2 for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eThree-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC and manual mill spindles\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for a broad range of general-purpose milling applications\u003c\/li\u003e\n  \u003cli\u003eRegular-length series provides a balance of reach and rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 3\/4 inch collet or end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the machine spindle is fully stopped and the machine is powered down or in a safe-stop state before changing tooling. Seat the shank fully and securely in the collet or end mill holder to the recommended engagement depth to prevent tool pullout during cutting. Verify runout with a dial indicator before commencing cuts, as excessive runout accelerates wear and reduces surface finish quality.\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 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\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix 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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 \/ -0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3125 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: C1-301\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: ROBBJACK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C1-301-24\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52057600164146,"sku":"C1-301-24","price":487.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f99f5e09fa3178d195da5e6fad8caf6.jpg?v=1790039008","url":"https:\/\/voomisupply.com\/products\/robbjack-c1-301-24-square-end-mill-3-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
