Built from cobalt steel and finished with a TiAlN coating, this bit handles elevated heat and abrasion better than standard HSS tooling. The 135-degree split point starts on contact without center-punching, reducing walking on flat or curved surfaces. At 2.75 inches overall length, the screw machine format keeps the tool close to the chuck for maximum rigidity in tight setups. It is suited for production machining, fabrication shops, and maintenance environments where cycle time and tool life matter.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in drill presses, CNC machining centers, lathes with live tooling, and hand-held industrial drills where a short, stiff bit is preferred. The 19\/64-inch diameter (0.2969 decimal inch) is a common size for clearance holes, tapping pilots, and close-tolerance bored features in steel, stainless, cast iron, and hard alloys. Right-hand cutting direction is standard for conventional drilling operations. A web-thinned parallel web configuration reduces thrust load and improves chip evacuation through the spiral flute.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction for heat resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering entry without center punching\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (2.75 inches OAL) maximizes rigidity in chuck-close setups\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard screw machine length drill bit compatible with any drill press, machining center, or handheld drill using a straight-cylindrical shank chuck accepting up to 19\/64-inch diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and serviced by machinists, tool and die technicians, and industrial maintenance professionals. Secure the straight-cylindrical shank fully in the chuck and verify runout before cutting. No coolant-through capability is present on this bit, so apply cutting fluid externally when drilling deep holes or hard materials to manage heat buildup. Inspect the cutting edges and TiAlN coating for wear or chipping before each use and replace when edge geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 19\/64 inches (0.2969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5625 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\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2500 to 0.3000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.255 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74131525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743963349298,"sku":"74131525","price":17.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2e72c7a5488b77f426337aaf92826a6.jpg?v=1788852045","url":"https:\/\/voomisupply.com\/products\/hertel-74131525-screw-machine-drill-bit-19-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
