Built to Series C8-201 standards, this stub-length tool features a 3\/16 inch cutting diameter, a 3\/8 inch length of cut, and a 1\/4 inch straight cylindrical shank. With 2 flutes and a 30-degree helix angle, it delivers efficient chip evacuation and clean edge finishes. The centercutting geometry allows both plunge and peripheral cuts. Uncoated solid carbide construction at material grade C2 provides rigidity and dimensional accuracy in demanding applications. Licensed machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual knee mills where a small-diameter stub-length tool is required for tight-tolerance slotting, profiling, and pocketing operations. The stub length format reduces deflection, making it effective in applications where rigidity is critical, such as hard material milling or shallow-depth cavity work. Right-hand cut and right-hand spiral flute configuration are standard for conventional milling spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction at grade C2 for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e3\/16 inch cutting diameter with a mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with spiral flute design for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables plunge entry and full-slot cutting\u003c\/li\u003e\n\u003cli\u003eStub length format minimizes tool deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute  -  compatible with standard CNC and manual spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill in the ROBBJACK C8-201 series, suitable for use with standard 1\/4 inch collets or end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the 1\/4 inch straight shank fully into the collet or holder and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator 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\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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 Type\u003c\/strong\u003e: Stub\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 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\u003eSeries\u003c\/strong\u003e: C8-201\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.125 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C8-201-06\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":51993048645938,"sku":"C8-201-06","price":58.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a49daf480ab1896078988c3df93d378b_9a96c80c-1ec2-49db-9392-c8a37e486a43.jpg?v=1789990796","url":"https:\/\/voomisupply.com\/products\/robbjack-c8-201-06-square-end-mill-3-16-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
