Built to a 1\/4 inch diameter with a 1\/2 inch length of cut and 2.5 inch overall length, this single-end tool features four flutes with a variable helix geometry and a 45-degree chamfer angle ground to a 0.002 inch chamfer width. The TiAlSiN nano-Si PVD coating provides elevated heat and wear resistance. Centercutting capability supports plunging, ramp-down, and helical interpolation entry strategies without a pre-drilled pilot hole. Machinists and tool-and-die professionals working in ferrous and high-temp alloy applications will find this tool suited to both roughing and finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use on steel, stainless steel, cast iron, superalloys, and titanium as primary workpiece materials, with non-ferrous metals as secondary applications. Typical use cases include shouldering, slotting, ramp-down milling, helical interpolation, drill-milling, and plunging and recessing operations. The straight-cylindrical shank and normal pitch flute configuration make it compatible with standard collet and end mill holder setups on vertical machining centers and manual knee mills alike. Coolant-through capability supports chip evacuation in deep-slot or high-feed operations where external flood coolant alone may be insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlSiN nano-Si PVD coating (nano-A) for oxidation resistance and extended tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eVariable helix flute geometry reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry, ramp-down, and helical interpolation without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eCoolant-through channels support chip evacuation in slotting and deep-cavity applications\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.002 inch chamfer width for consistent edge-break geometry on finished parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates edge wear on carbide tooling and reduces dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\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: 0.500 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.500 inches (2-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlSiN nano-Si PVD (nano-A)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\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-Cylindrical\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: 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and 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\u003eWeight\u003c\/strong\u003e: 0.01 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: 9068750063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739881406770,"sku":"9068750063500","price":142.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07cde72d58c89fce9e0ab1d601561ca0.jpg?v=1788819999","url":"https:\/\/voomisupply.com\/products\/guhring-9068750063500-corner-chamfer-end-mill-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
