Built on the Series 6872 platform, this single-end tool features a 0.250 inch cutting diameter, a 0.500 inch length of cut, and a 45-degree chamfer angle with a 0.0040 inch chamfer width. The three-flute, right-hand helical geometry combined with a variable helix design reduces chatter and improves chip evacuation. A TiAlSiN PVD nano-Si coating delivers thermal resistance and surface hardness suited to high-feed milling in ferrous and exotic alloys. Machinists and CNC operators in job shop, aerospace, and general manufacturing environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for shouldering, slotting, ramp-down, helical interpolation, drill milling, and plunging and recessing operations. The extended-reach neck  -  0.875 inch reach length with a 0.238 inch neck diameter  -  allows access to deep pockets and stepped features without tool change. The centercutting capability enables direct plunge entry. Primary workpiece materials include steel, stainless steel, cast iron, and superalloys including titanium. Non-ferrous metals are listed as a secondary material application. The straight cylindrical 0.250 inch shank fits standard ER and end mill holders with h6 shank tolerance for accurate runout.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix geometry reduces harmonic vibration during high-feed cuts\u003c\/li\u003e\n  \u003cli\u003eTiAlSiN PVD nano-Si coating improves heat resistance and tool life in steel and superalloy machining\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 0.875 inches with reduced neck diameter of 0.238 inches for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.0040 inch chamfer width for controlled edge breaking and corner preparation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction with normal pitch and micrograin carbide substrate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers and manual mills accepting a 1\/4 inch straight cylindrical shank.

Secure the shank in a compatible end mill holder or collet chuck, ensuring adequate clamping depth to prevent pullout under load. Verify spindle and holder runout before operation, as micrograin carbide tooling is sensitive to runout-induced fracture. Coolant through is not supported on this tool; apply external flood or mist coolant directed at the cutting zone as required by the workpiece material.\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: 3\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h10\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: 0.0040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.238 inches (6.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\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\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlSiN PVD nano-Si\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\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\u003eSeries\u003c\/strong\u003e: 6872\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: 9068720063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739946582322,"sku":"9068720063500","price":76.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b8e49fb327c066286078de55818f2b6.jpg?v=1788820629","url":"https:\/\/voomisupply.com\/products\/guhring-9068720063500-corner-chamfer-end-mill-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
