It features a 3\/16-inch cutting diameter with a 1-1\/8-inch length of cut, giving it reach suited to slotting, profiling, and pocketing in confined workspaces. The four-flute geometry with a 30-degree helix angle promotes smooth chip evacuation and improved surface finish. The bright, uncoated finish on micrograin carbide stock makes this end mill well-suited to use with cutting fluids and in applications where coating adhesion is not required. It is a single-end, centercutting tool, allowing plunge entry directly into the workpiece. Machinists and toolroom operators working in job shops and production environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical machining centers, CNC mills, and manual milling machines running fractional-inch tooling. Its 3\/16-inch shank diameter matches common collet and end mill holder sizes in that fractional range. The 3-inch overall length provides clearance for standard tool holders without excessive overhang. Right-hand cut and right-hand flute direction are the standard configuration for conventional milling setups. The HSQSC4-CC series designation places it in a family of center-cutting square end mills intended for general-purpose material removal across ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eFour flutes with 30-degree helix angle for smooth cutting action and efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with flood coolant and cutting oil applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard CNC and manual mill setups\u003c\/li\u003e\n\u003cli\u003eSingle-end tool with 3\/16-inch shank for use in standard fractional collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a fractional-inch single-end square end mill for use in collets, end mill holders, and chucks sized for 3\/16-inch shanks on CNC machining centers and manual mills.

Ensure the machine spindle is fully stopped and the control is in an e-stop or locked state before inserting or removing the end mill from the holder. Verify collet or holder bore size matches the 3\/16-inch shank diameter before clamping. Minimize tool overhang beyond the holder to reduce deflection and vibration during cutting.\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: 1-1\/8 inches (1.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: Bright\/Uncoated\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSQSC4-CC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728844947762,"sku":"750090","price":35.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d1f15d9310d4d9b52a09b00de92cc2b.jpg?v=1788696696","url":"https:\/\/voomisupply.com\/products\/hertel-750090-square-end-mill-3-16-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
