Designed for right-hand cut and right-hand spiral flute operation, it features a 0.035-inch cutting diameter with a 0.105-inch length of cut and a 30-degree helix angle. The two-flute geometry promotes efficient chip evacuation in confined cuts, while the centercutting design allows plunge entry. This tool is intended for use by machinists and CNC operators working in aerospace, medical device, mold, and general precision machining applications where tight tolerances and small-diameter toolpaths are required.\u003c\/p\u003e\n\u003cp\u003eThe SR-2-035 belongs to ROBBJACK's SR-2 series of regular-length micro end mills. Its 1\/8-inch straight cylindrical shank fits standard collet chucks and tool holders sized for that bore. The uncoated solid carbide construction, ground to Tuffy material grade, makes it well-suited for non-ferrous metals, plastics, and other materials where an uncoated substrate performs without edge buildup. The 1.5-inch overall length keeps the tool compact for short-reach setups where rigidity is critical at small diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.035-inch cutting diameter with mill diameter tolerance of plus 0.0005 \/ minus 0.0005 inches for consistent sizing\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003e30-degree spiral flute helix angle balances cutting forces and chip flow at micro diameters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute geometry for standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSolid carbide Tuffy grade construction provides hardness and wear resistance without a coating\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 1\/8-inch shank with tight shank diameter tolerance of minus 0.0001 \/ minus 0.0002 inches for secure collet grip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision end mill for use in CNC machining centers and manual mills equipped with collet toolholding systems accepting a 1\/8-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and all motion axes locked. Secure the shank in a clean, properly sized collet or end mill holder to the full recommended engagement depth before tightening. Inspect the cutting edges under magnification before mounting, as micro-diameter carbide tools are brittle and sensitive to handling damage. Follow applicable shop safety procedures and machine manufacturer guidelines for feeds, speeds, and runout verification before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.105 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.040 \/ minus 0.040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 \/ minus 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix 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\u003eCentercutting\u003c\/strong\u003e: Yes\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: Tuffy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SR-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: ROBBJACK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SR-2-035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52082053382450,"sku":"SR-2-035","price":40.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee17f1a62b14df315af2b212cd542090_e388a0cc-3d0c-4480-822e-6d80b267f147.jpg?v=1790056562","url":"https:\/\/voomisupply.com\/products\/robbjack-sr-2-035-square-end-mill-0-035-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
