Built from micrograin solid carbide, it delivers rigidity and edge retention that high-speed steel tooling cannot match at elevated cutting speeds. The 3\/16-inch diameter pairs with a 37-degree right-hand spiral helix to promote efficient chip evacuation and reduce heat buildup in the cut zone. A ZrN (zirconium nitride) coating adds surface hardness and lubricity, extending tool life in abrasive materials. This end mill is centercutting, allowing plunge operations in addition to standard peripheral and slot milling. Machinists and toolroom operators running CNC mills, VMCs, and manual knee mills install this tool.\u003c\/p\u003e\u003cp\u003eThe 314512 is suited for slot milling, profiling, and light ramping operations on ferrous metals, aluminum, plastics, and composites. Its 3\/8-inch length of cut falls within a 0.30 to 0.50-inch length-of-cut range, making it a practical choice for shallow-to-mid-depth features in production and prototype work. The 3\/16-inch shank diameter fits standard ER collets and end mill holders common in most machining centers. No extended reach is incorporated, keeping deflection low during aggressive side milling passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for superior hardness and edge stability\u003c\/li\u003e\n\u003cli\u003eZrN coating improves surface lubricity and wear resistance in abrasive cuts\u003c\/li\u003e\n\u003cli\u003e37-degree right-hand helix promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eTight mill diameter tolerance of +0.000 \/ -0.005 inches ensures consistent feature sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 3\/16-inch shank, three-flute square end mills in standard ER collet chucks and end mill holders used on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before changing tooling. Seat the shank to the minimum insertion depth recommended by the collet or holder manufacturer to maximize grip and minimize runout. Inspect collet condition before use, as a worn or contaminated collet will increase runout and reduce tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.300 - 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 314512\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739615199538,"sku":"314512","price":49.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2c2ef65ee8f6fcebd94c478410c4937.jpg?v=1788816960","url":"https:\/\/voomisupply.com\/products\/accupro-314512-square-end-mill-3-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
