It features a 0.1875-inch cutting diameter, a 0.625-inch length of cut, and a 6-flute configuration that increases feed rates and improves surface finish compared to lower-flute-count tools. The micrograin carbide substrate provides hardness and wear resistance, while the TiAlN coating adds thermal protection for high-speed and dry cutting applications. This is a single-end, right-hand cut tool with a right-hand spiral flute and a 30-degree helix angle. Machinists and tool-and-die professionals working on CNC mills and machining centers are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe 461-187511 is suited for finish milling, slotting, and profiling operations in shop and production environments. Its 0.1875-inch shank diameter matches the cutting diameter, making it compatible with standard collet chucks and end mill holders sized for 3\/16-inch tooling. The 2-inch overall length keeps the tool rigid during light-to-moderate depth cuts. It is appropriate for use on CNC vertical machining centers and manual knee mills where close-tolerance work is required. The centercutting geometry allows plunge entry, adding versatility to the tool's application range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating supports high-speed and dry cutting by reducing thermal buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e6-flute design increases chip load per tooth and improves surface finish in finishing passes\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting forces and chip evacuation in spiral flute geometry\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/16-inch collet chucks and end mill holders on CNC machining centers and manual mills.

Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before loading or unloading the tool. Verify collet condition and holder runout before seating the tool, as excessive runout accelerates wear on small-diameter carbide end mills. Follow applicable shop safety standards for guarding and chip containment during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eSeries\u003c\/strong\u003e: 461\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 461-187511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744868696370,"sku":"461-187511","price":40.75,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/osg-461-187511-square-end-mill-6-flute-tialn-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
