Manufactured from cobalt high-speed steel (HSCO), it delivers superior heat resistance compared to standard HSS bits, making it well suited for demanding production and maintenance environments. The 135-degree split point geometry reduces walking and thrust, enabling cleaner entry without a center punch. At 1-11\/16 inches overall length, this stub-length bit provides added rigidity to minimize deflection in short-reach drilling applications. Wire gauge size 48 corresponds to a decimal diameter of 0.0760 inches. Installation is handled by qualified machinists, tool-and-die technicians, and maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThe HERTEL 74131004 is designed for screw machine operations, CNC drilling, and general-purpose production drilling where a short, rigid bit is required. The stub length format reduces chatter and overhang in turret lathes, screw machines, and drill presses. The regular spiral flute and parallel web configuration support consistent chip evacuation in ferrous and non-ferrous metals. This bit does not support coolant-through operation and is intended for use with external cutting fluid or dry cutting where appropriate for the material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt (HSCO) construction provides superior heat and wear resistance for drilling hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and lowers required thrust force at entry\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length of 1-11\/16 inches overall increases rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned geometry with parallel web configuration supports efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral flute with 11\/16-inch flute length\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for use in standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eStraw finish on cobalt substrate; no additional coating applied\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitution for wire gauge size 48 screw machine length drill bits in standard drill chucks and collets accepting a straight cylindrical shank in the 0.0760-inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a standard drill chuck or collet system matched to the straight shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm chuck runout is within acceptable tolerance for the diameter being drilled, as excessive runout at small diameters accelerates wear and increases breakage risk. Apply appropriate cutting fluid for the material being drilled unless dry cutting is specified.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0760 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (HSCO)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 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 Point\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.0000 to 0.1000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 74131004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742624416050,"sku":"74131004","price":38.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94498d2395ba5d22d89cf8bbdaa6396c.jpg?v=1788838423","url":"https:\/\/voomisupply.com\/products\/hertel-74131004-cobalt-screw-machine-drill-bit-size-48","provider":"Voomi Supply","version":"1.0","type":"link"}
