This single-end mill measures 0.25 inches in diameter with a 0.5-inch length of cut and a 2.5-inch overall length. It features a 45-degree chamfer angle and a 0.004-inch chamfer width applied at the corner, protecting the cutting edge and producing a consistent chamfer on workpiece edges in a single pass. The TiAlSiN nano-Si PVD coating provides thermal resistance and wear protection suited to high-speed cutting in ferrous and exotic materials. A variable helix design reduces harmonics and chatter during aggressive cuts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use on CNC machining centers and manual mills where precision edge preparation is required. Primary workpiece materials include steel, stainless steel, cast iron, and superalloys and titanium. Secondary suitability covers non-ferrous metals. Supported operations include shouldering, slotting, ramp-down entry, helical interpolation, drill milling, plunging, and recessing. The centercutting geometry allows direct plunge entry, and the coolant-through design supports both external and internal coolant delivery for chip evacuation and thermal management in deep-reach scenarios. The 0.875-inch reach length and 0.238-inch neck diameter provide clearance in pocketing and stepped-bore applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree corner chamfer with 0.004-inch chamfer width for consistent edge preparation\u003c\/li\u003e\n  \u003cli\u003eTiAlSiN nano-Si PVD coating for thermal and wear resistance in steel, stainless, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eVariable helix geometry reduces chatter and improves surface finish during roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports direct plunge entry and helical interpolation\u003c\/li\u003e\n  \u003cli\u003eCoolant-through construction aids chip evacuation and heat control in deep-reach cuts\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate maintains edge integrity at elevated cutting temperatures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 0.25-inch straight-cylindrical shank toolholders including ER collet chucks, shrink-fit holders, and hydraulic chucks.

Ensure the machine spindle is at a full stop and the control is in an estop or locked-out state before loading or removing the tool. Verify holder bore and collet size match the 0.25-inch shank diameter before seating the tool; shank diameter tolerance is h6. Confirm runout is within acceptable limits after clamping to protect both the tool and workpiece surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.238 inches (0.24 mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlSiN nano-Si PVD\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\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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 Materials\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6873\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: 9068730063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51743132320050,"sku":"9068730063500","price":142.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a3ae6ec1c76f730ff49be5b68c2d62a.jpg?v=1788843065","url":"https:\/\/voomisupply.com\/products\/guhring-9068730063500-corner-chamfer-end-mill-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
