Built from cobalt high-speed steel (HSCO), it delivers superior heat and wear resistance compared to standard HSS tooling. The bit features a 135-degree split point that reduces walking and cutting pressure, enabling fast entry without a center punch. At 1.75 inches overall length with a 0.75-inch flute length, this stub-length geometry provides added rigidity for drilling gummy, abrasive, or hard materials. Licensed electricians, machinists, HVAC technicians, and plumbers use screw machine bits where short stiff drills outperform jobber-length tooling.\u003c\/p\u003e\n\u003cp\u003eThe 74130980 is suited for drilling wire gauge size 46 holes  -  0.0810 inches in diameter  -  in metal fabrication, sheet metal work, and general mechanical assembly. Its stub length makes it a practical choice in drill presses, CNC machines, and hand drills where clearance is limited. The regular spiral flute and parallel web configuration support consistent chip evacuation across a range of base materials including stainless steel, alloy steel, and cast iron where cobalt tooling is preferred over standard HSS.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt (HSCO) construction for elevated heat and wear resistance in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces cutting thrust and eliminates pilot dimpling on most surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip flow and reduces torque at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length of 1.75 inches total with 0.75-inch flute for maximum rigidity\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting with regular spiral flutes  -  compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard keyless and keyed chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-grade screw machine drill bit for use in standard drill presses, CNC machining centers, and hand-held drills accepting a straight cylindrical shank in the applicable shank diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of small-diameter drill bits should be performed by qualified machinists or trade professionals familiar with proper feed rates and spindle speeds for cobalt tooling. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Do not run cobalt bits without appropriate cutting fluid or coolant when drilling hard metals, as dry cutting accelerates tip wear. Inspect the cutting edges before each use  -  small-diameter bits are susceptible to breakage if run at excessive feed pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0810 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (HSCO)\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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSCO135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74130980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743415599410,"sku":"74130980","price":41.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b6c0bb100f233c51e6b4b914ad95321.jpg?v=1788846804","url":"https:\/\/voomisupply.com\/products\/hertel-74130980-cobalt-screw-machine-drill-bit-size-46","provider":"Voomi Supply","version":"1.0","type":"link"}
