It measures 1\/4 inch (0.2500 inch) in diameter with a 135-degree standard point angle and a TiAlN coating that extends tool life at elevated cutting temperatures. The spiral flute geometry and web-thinned, tapered web configuration reduce thrust and improve chip evacuation in deep-hole passes. With a flute-to-diameter ratio of 20xD, this bit reaches drilling depths up to approximately 152.48 mm. Coolant-through capability supports high-speed, uninterrupted cuts. It is sized and specified for use by machinists and toolroom technicians in metalworking and fabrication shops.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for primary use in cast iron, stainless steel, and steel, with secondary suitability for aluminum and titanium alloy workpieces. The Series 6511 designation places it in GUHRING's high-performance submicron carbide grade line, designed for applications where standard HSS or cobalt bits cannot maintain dimensional accuracy or tool life. Typical install scenarios include CNC machining centers, drill presses, and manual mills where consistent hole depth and diameter tolerance are critical. The straight-cylindrical shank with an 8.00 mm shank diameter seats in standard ER or drill chuck toolholders without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid submicron carbide construction with TiAlN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports continuous chip removal in deep hole passes\u003c\/li\u003e\n\u003cli\u003e20xD flute-to-diameter ratio with maximum drilling depth of 152.48 mm\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute, straight-cylindrical shank fits standard toolholding systems\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance held to +0.000 to -0.015 mm for precise hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production drill in GUHRING Series 6511. Primary workpiece materials are cast iron, stainless steel, and steel (ISO material codes K, M, P); secondary workpiece materials are aluminum and titanium alloy (ISO codes N, H, S). No additional model-specific compatibility data was provided.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified machinist or toolroom technician. Before mounting, confirm the machine spindle is fully powered down and locked out per applicable shop safety procedures. Seat the straight-cylindrical shank fully and evenly in the toolholder and verify runout before commencing a cut. Activate coolant-through supply before beginning the drilling cycle to prevent chip packing and premature tool wear in deep-hole applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 202.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 162.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 152.48 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 20xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.015 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6511\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Proposition 65\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9065110063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755597758770,"sku":"9065110063500","price":800.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ea6d55cacf0f6808ef90a43f04528b6.jpg?v=1788956586","url":"https:\/\/voomisupply.com\/products\/guhring-9065110063500-extra-length-carbide-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
