With a cutting diameter of 0.052 inches and a 5\/32-inch length of cut, this tool is built for small-feature work such as slotting, profiling, and pocket milling in dies, molds, and precision machined components. The 1\/8-inch straight-cylindrical shank fits standard collet chucks. At 1-1\/2 inches overall length, the tool maintains rigidity in short-reach setups. Solid carbide construction under the SR-2 Tuffy material grade delivers hardness and wear resistance suited to challenging workpiece materials.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual knee mills where small-diameter, close-tolerance cuts are required. Typical applications include fine detail work on mold cavities, instrument components, and medical or aerospace parts where burr-free edges and dimensional accuracy are critical. The centercutting geometry allows plunge entry as well as conventional side milling. Right-hand cut and right-hand spiral flute configuration is standard for most CNC spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.052-inch cutting diameter with tight mill diameter tolerance of plus or minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction, Tuffy material grade for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e2-flute spiral configuration promotes chip evacuation in small-slot and pocket work\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces and surface finish\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications where coating is not required or where re-sharpening is planned\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for 1\/8-inch straight-shank collet systems used in CNC machining centers and precision milling machines requiring small-diameter square end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1\/8-inch shank fully into the collet or toolholder and torque the retention nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, especially at this diameter where deflection and runout have an outsized effect on tool life and dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.052 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.156 inches (5\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\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\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 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\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SR-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: SR-2-052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":68103502922034,"sku":"SR-2-052","price":39.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee17f1a62b14df315af2b212cd542090_ca0df67e-cd79-4cd9-a951-484468c55336.jpg?v=1793305764","url":"https:\/\/voomisupply.com\/products\/robbjack-sr-2-052-square-end-mill-0-052-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
