The bit measures 1\/4 inch (0.2500 inches) in diameter with a 322 mm overall length and a 282 mm spiral flute length, giving it a 40xD flute-to-diameter ratio suited for deep-reach applications. A TiAlN coating improves heat resistance and extends tool life at elevated cutting speeds. The 135-degree standard point angle and web-thinned, tapered web geometry reduce entry thrust and help center the bit without a pilot hole. Right-hand cutting direction is standard. This is a professional-grade cutting tool installed by machinists and maintenance technicians in industrial and trade settings.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for deep hole drilling in cast iron, stainless steel, and steel as primary workpiece materials, with aluminum and titanium alloy listed as secondary compatible materials. The straight-cylindrical shank measures 8.00 mm (0.3150 inches) in diameter with a 36 mm shank length, fitting standard drill chucks and collet holders used in CNC machining centers, drill presses, and manual machines. Maximum drilling depth is 272.48 mm (10.7280 inches). The coolant-through design supports internal coolant delivery, making this bit well suited for production drilling cycles where chip evacuation and heat control are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction using DK460UF grade material for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for elevated temperature resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e40xD flute-to-diameter ratio enables deep hole drilling up to 272.48 mm depth\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant or air delivery for chip evacuation\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust force at entry and improves centering\u003c\/li\u003e\n  \u003cli\u003e135-degree standard point angle suitable for cast iron, stainless steel, and steel\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral geometry with right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron, stainless steel, and steel as primary workpiece materials (material codes K, M, P), with aluminum and titanium alloy as secondary workpiece materials (material codes N, S, H).

Always power down and lock out the machine before mounting or removing the bit. Verify chuck or collet runout is within acceptable tolerance before use, as excessive runout accelerates wear on carbide tooling. When using the coolant-through feature, confirm coolant pressure and flow rate are compatible with the machine spindle before beginning the drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 322 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 282 mm (11.1024 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 272.48 mm (10.7280 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm\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 (DK460UF grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 40xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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: 6514\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Deep Hole Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Prop 65\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 9065140063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737717670194,"sku":"9065140063500","price":1332.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b9fdafc648143950772d415cc489212.jpg?v=1788792701","url":"https:\/\/voomisupply.com\/products\/guhring-9065140063500-extra-length-carbide-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
