Built to fractional inch standards, it features a 3\/16 inch (0.1875 inch) mill diameter and a 5\/8 inch length of cut, making it well suited for slotting, profiling, and peripheral milling in tight-tolerance applications. The four-flute, right-hand spiral geometry promotes efficient chip evacuation while maintaining surface finish quality. A diamond-like carbon (DLC) coating reduces friction and heat buildup at the cutting edge, extending tool life in demanding steel-cutting environments. At 2.0 inches overall length, this is a regular-length, single-end tool intended for use in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is targeted at machinists and tool-and-die professionals working in job shops, production facilities, and maintenance departments. The 3\/16 inch diameter and regular length make it a practical choice for fine-detail work, narrow slot milling, and contour profiling in steel components. The straight shank is compatible with standard collet chucks and end mill holders sized for 3\/16 inch shank diameter. Center-cutting capability allows plunge entry without a pre-drilled pilot hole, adding versatility to the setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in steel-cutting applications\u003c\/li\u003e\n\u003cli\u003eDLC (diamond-like carbon) coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes promote efficient chip evacuation and consistent surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting force and chip flow in ferrous materials\u003c\/li\u003e\n\u003cli\u003eSingle-end, straight shank fits standard 3\/16 inch collet chucks and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fractional-inch tooling option for CNC machining centers and manual mills using 3\/16 inch straight-shank end mill holders or collet chucks.

Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before torquing the retention hardware. Verify runout with a dial indicator after clamping to confirm proper seating 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: 0.1875 inches (3\/16 inch, 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches (5\/8 inch, 15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch, 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 inches (50.80 mm)\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 524\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14981786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744847888690,"sku":"14981786","price":55.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_04165a33-2953-421e-b462-9caac7c8230d.jpg?v=1788861485","url":"https:\/\/voomisupply.com\/products\/accupro-14981786-3-16-inch-4-flute-carbide-square-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
