It carries a TiAlN coating and features a 135-degree RT100 T point with web thinning for reliable self-centering and reduced thrust. At 0.437 inches in diameter with a 15xD flute-to-diameter ratio, this drill reaches a maximum drilling depth of 7.769 inches. Internal coolant-through capability supports chip evacuation and thermal management during extended cuts. The straight-cylindrical shank seats directly into standard toolholders. Licensed machinists and CNC operators working in aerospace, automotive, and precision machining shops are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for deep hole drilling applications in cast iron, stainless steel, and carbon and alloy steels as primary workpiece materials. It also performs in aluminum and titanium alloy as secondary materials. The Series 6509 designation places it in Guhring's high-performance carbide drill lineup, suitable for horizontal and vertical machining centers running coolant-through tooling. The right-hand cutting direction and regular spiral geometry make it compatible with standard CNC spindle configurations. Typical applications include through-hole and blind-hole drilling in structural and precision components where hole depth-to-diameter ratio exceeds what a jobber-length drill can achieve.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiAlN coating for heat resistance and tool life in ferrous and exotic materials\u003c\/li\u003e\n  \u003cli\u003eRT100 T point geometry with web thinning reduces entry thrust and improves centering accuracy\u003c\/li\u003e\n  \u003cli\u003e135-degree drill point angle suited for hard and interrupted materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design flushes chips and controls heat at depths up to 7.769 inches\u003c\/li\u003e\n  \u003cli\u003e15xD flute-to-diameter ratio enables deep hole drilling in a single setup\u003c\/li\u003e\n  \u003cli\u003eh7 shank diameter tolerance ensures consistent fit in precision toolholders and collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement drill in the Guhring Series 6509 high-performance carbide line. Suitable for use in coolant-through toolholding systems that accept a straight-cylindrical shank with 12 mm shank diameter. Primary workpiece materials include cast iron (K), stainless steel (M), and steel (P); secondary materials include aluminum (N) and titanium alloy (S) per ISO material group coding.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Confirm the toolholder or collet is rated for coolant-through use and that the machine spindle coolant pressure is within the toolholder manufacturer's specifications before beginning. Power down and lock out the machine before loading or unloading the drill. Inspect the shank and collet bore for chips or contamination before seating the tool to maintain h7 tolerance fit and prevent runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 7.769 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 263 mm (approximately 10.35 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 214 mm (approximately 8.43 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 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\u003ePoint Type\u003c\/strong\u003e: RT100 T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Deep Hole Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Aluminum, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6509\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.257 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Proposition 65\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: 9065090111100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51754349134130,"sku":"9065090111100","price":1049.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96013ea6b545bbd29c5a8217e08ae9a6_3186c8c2-f8d8-4f08-887f-d43e800c0982.jpg?v=1788944550","url":"https:\/\/voomisupply.com\/products\/guhring-9065090111100-extra-length-drill-bit-0-437in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
