It cuts at 0.2610 inches in diameter with a 135-degree split point that reduces walking and lowers entry force on hard or tough stock. The web-thinned, tapered web design improves chip evacuation and keeps cutting pressure consistent through the full depth of cut. At 4-1\/8 inches overall length with a 2-7\/8-inch flute, it fits standard drill chucks without an adapter. Two right-hand spiral flutes move chips out efficiently. This bit is rated heavy duty and meets NAS specification requirements. Machinists, maintenance techs, and fabricators reach for this style when drilling ferrous and non-ferrous metals in production or repair work.\u003c\/p\u003e\u003cp\u003eThe 66693805 is suited to holemaking in metals, plastics, and composite materials where a jobber-length bit is appropriate. Its 0.2610-inch diameter falls in the 0.2500 to 0.3000-inch size range, making it a direct replacement wherever a letter G bit is called out. The straight-cylindrical shank seats in standard three-jaw chucks on drill presses, hand drills, and CNC machining centers. It is sold individually, making it practical as a single-piece replacement or bench stock replenishment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter G diameter: 0.2610 inches, falling in the 0.2500 to 0.3000-inch range\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and lowers thrust requirements on entry\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and extends tool life versus uncoated HSS\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web improves chip flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003e2-7\/8-inch flute length with regular spiral provides consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eNAS specification designation; heavy-duty grade construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit for use in any three-jaw chuck or collet system accepting a 0.2610-inch straight-cylindrical shank, including drill presses, hand drills, and CNC machining centers requiring a letter G diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the chuck and verify runout before starting the cut. Use appropriate cutting fluid or coolant for the workpiece material to preserve coating life and edge integrity. Confirm the drill press or machine spindle speed is set to a feed and speed appropriate for the workpiece material and bit diameter before operation. Wear eye protection and secure the workpiece in a vise or fixture; never hand-hold material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Split\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize Range\u003c\/strong\u003e: 0.2500 to 0.3000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66693805\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742493114674,"sku":"66693805","price":16.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6284e496370672a09f2d9ef97fc3099.jpg?v=1788837786","url":"https:\/\/voomisupply.com\/products\/hertel-66693805-jobber-drill-bit-letter-g-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
