It carries a 5\/16 inch (0.3125 inch) diameter, a 1-1\/4 inch length of cut, and a 4-flute helical geometry with a 48-degree helix angle. The nano-A AlTiN PVD coating provides heat resistance and extended tool life in difficult-to-machine alloys. The chamfer geometry is ground to a 0.004 inch width at a 45-degree angle, producing a consistent edge break or chamfer form in a single pass. This is a single-end, centercutting tool with a straight cylindrical shank, making it suitable for use in standard collet chucks and end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for shops and field machinists working in aerospace, energy, and precision manufacturing environments where steel, stainless, superalloys, and titanium are primary workpiece materials. Non-ferrous metals are listed as a secondary workpiece application. The extra-long 3 inch overall length provides reach clearance in deep pockets or stepped features. Supported operations include shouldering, slotting, ramp-down, helical interpolation, drill milling, and plunging and recessing, making it a versatile choice when a single tool must handle multiple operations in a setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003enano-A AlTiN PVD coating rated for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.004 inch chamfer width for precise edge preparation\u003c\/li\u003e\n  \u003cli\u003e48-degree high helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunging, ramp-down, and helical interpolation entries\u003c\/li\u003e\n  \u003cli\u003eNormal pitch, 4-flute layout supports both roughing and finishing operations\u003c\/li\u003e\n  \u003cli\u003eExtra-long 3 inch OAL with 5\/16 inch straight-cylindrical shank fits standard collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with standard 5\/16 inch collet chucks or end mill holders accepting a straight-cylindrical shank.

Ensure the spindle is fully stopped and the machine is in a safe lockout state before inserting or removing the tool. Seat the shank fully into the holder to the recommended gauge depth and torque the collet nut or set screw per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout in solid carbide tooling accelerates chipping and premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 48 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003c\/strong\u003e: nano-A AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6774\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9067740079400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51736377491762,"sku":"9067740079400","price":136.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/013ea013cf330f216bcbaabdc1590763_dc865d71-0cce-4a09-8f74-a3f39e15fb43.jpg?v=1788777580","url":"https:\/\/voomisupply.com\/products\/guhring-9067740079400-corner-chamfer-end-mill-5-16in-4f","provider":"Voomi Supply","version":"1.0","type":"link"}
