Built with 3 flutes and a chipbreaker geometry, it breaks chips aggressively to reduce heat and tool pressure during roughing passes while leaving a finish suitable for many final applications. The 7\/16 inch diameter cutter features a 0.02 inch corner radius on a corner radius end profile, a 35-degree helix angle, and a TiCN (titanium carbonitride) coating for improved wear resistance and lubricity. Installed by machinists and tool-and-die professionals in CNC and manual milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous metals where combined roughing and finishing passes are required. The single-end, right-hand cutting, right-hand flute configuration makes it a standard fit for conventional vertical and horizontal milling setups. The chipbreaker design is especially effective in applications where long, stringy chips are a concern, such as aluminum alloys, steel, and stainless steel. The 1 inch length of cut and 2-3\/4 inch overall length position it for general-purpose cavity and profile milling without extended-reach tooling requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChipbreaker flute geometry reduces chip load and heat during roughing passes\u003c\/li\u003e\n\u003cli\u003e0.02 inch corner radius protects cutting edges and reduces stress concentration at corners\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and wear resistance over uncoated carbide\u003c\/li\u003e\n\u003cli\u003e35-degree helix angle promotes smooth cutting action and chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single-end configuration for standard milling setups\u003c\/li\u003e\n\u003cli\u003e1 inch length of cut with 2-3\/4 inch overall length for general-purpose depth applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill compatible with 7\/16 inch collets, end mill holders, and shrink-fit tooling systems used in 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 following shop safety protocols. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the 7\/16 inch shank fully and evenly in the holder and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before initiating a cutting pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 117\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 117-02812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51985665720626,"sku":"117-02812","price":141.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/036022c77995a7710414c3c7ac20a7d1.jpg?v=1789985638","url":"https:\/\/voomisupply.com\/products\/promax-117-02812-roughing-finishing-end-mill-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
