Built from cobalt high-speed steel (HSCo), it handles the elevated heat and cutting forces common when drilling hardened steels, stainless alloys, and tough ferrous materials. The 135-degree split point reduces walking and requires less thrust to start the cut. At 3-5\/16 inches overall length and 13\/32 inch diameter, this stubby-format bit fits standard drill chucks and short-reach setups where a jobber-length bit would flex or chatter.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production machining environments, job-shop drill presses, CNC machining centers, and handheld power tools where short overall length improves rigidity. The straight cylindrical shank seats securely in keyed or keyless chucks. The straw finish indicates the cobalt alloy composition and is left uncoated, making the bit well-suited for cutting cast iron, carbon steel, alloy steel, and stainless steel. Machinists, millwrights, pipefitters, and general maintenance technicians are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt HSCo construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 3-5\/16 inches OAL improves rigidity in tight setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with web-thinned parallel web for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry balances chip clearance and cutting edge strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard screw machine length drill bit with a straight cylindrical shank, compatible with keyed and keyless drill chucks accepting 13\/32 inch shanks on drill presses, lathes, CNC machining centers, and handheld power drills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the chuck and verify runout before drilling to prevent premature wear or breakage. Use cutting fluid or coolant appropriate for the workpiece material to manage heat, as cobalt bits are heat-resistant but not immune to thermal damage from dry cutting in dense alloys. Ensure the drill press table or workpiece is clamped before beginning the cut. This bit does not support coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13\/32 inch (0.4062 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-15\/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\u003eTool Material\u003c\/strong\u003e: Cobalt High-Speed Steel (HSCo)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw (Uncoated)\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 Spiral\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, 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\u003eSeries\u003c\/strong\u003e: HSCO135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 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: 74130378\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730820432178,"sku":"74130378","price":24.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b5b340e63db9cb7f05a957a3bba0cf1.jpg?v=1788723395","url":"https:\/\/voomisupply.com\/products\/hertel-74130378-screw-machine-drill-bit-13-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
