Built from cobalt high-speed steel, this bit handles heat-resistant alloys, stainless steel, and hard ferrous metals that standard HSS tooling struggles with. The 135-degree split point reduces thrust and starts on contact without a center punch. Overall length is 2-7\/16 inches with a 1-5\/16-inch flute length, making it compact and rigid for short-hole work in drill presses and CNC machines. The straight cylindrical shank fits standard drill chucks. A right-hand, regular spiral flute with web-thinned parallel web geometry improves chip evacuation and cutting efficiency.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized to wire gauge No. 1, with a decimal inch diameter of 0.2280 inches, placing it in the 0.2000 to 0.2500 inch range. Screw machine length bits are the go-to choice in production environments where rigidity matters more than reach. Typical applications include metalworking shops, machine shops, aerospace MRO, and any operation requiring close-tolerance drilling in hard or abrasive stock. The bit is well-suited for use in drill presses, mill-drill machines, and CNC machining centers where short-reach tooling improves accuracy and reduces deflection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction withstands elevated drilling temperatures in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates the need for center-punching on flat stock\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web geometry improves chip flow and reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides superior rigidity over jobber-length bits in short-hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute with no coolant-through requirement keeps tooling cost low for general production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cobalt screw machine drill bit for metalworking operations requiring a wire gauge No. 1 (0.2280 inch) diameter straight-shank drill in drill presses, mill-drills, and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Secure the straight shank firmly in a keyed or keyless drill chuck before operation and verify runout before committing to production work. Ensure the workpiece is clamped or fixtured — never hand-hold metal stock during drilling. Follow shop safety practices and applicable OSHA machining guidelines; use cutting fluid appropriate for the workpiece material to extend tool life when drilling stainless or high-alloy steel.\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: No. 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High-Speed Steel\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: 2-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-5\/16 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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\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\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: 0.2000 to 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.276 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: 74130113\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748721459506,"sku":"74130113","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5825e55029ae50d30bd5590b394f548.jpg?v=1788897288","url":"https:\/\/voomisupply.com\/products\/hertel-74130113-cobalt-screw-machine-drill-bit-size-1","provider":"Voomi Supply","version":"1.0","type":"link"}
