Built from cobalt high-speed steel (HSCO), it delivers improved heat and wear resistance compared to standard HSS bits, making it suitable for harder workpiece materials including stainless steel, cast iron, and high-nickel alloys. The 135-degree split point geometry reduces walking on entry and requires less feed force than a conventional 118-degree point. At 1.875 inches overall length, the stub-length body provides added rigidity and reduced deflection in screw machine and drill press setups.\u003c\/p\u003e\u003cp\u003eThis bit is sized at 0.125 inches (1\/8 inch) diameter and is intended for use in screw machines, CNC drill presses, and manual drilling operations where a short, rigid bit is preferred over jobber-length tooling. The right-hand spiral flute configuration handles standard clockwise-rotation spindles. Web-thinned construction improves chip evacuation and reduces thrust load at the cutting edge. Machinists, tool and die workers, and metal fabrication professionals are the primary installers of this tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt HSS construction for heat resistance when drilling hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walking and lowers required feed pressure\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web improves chip flow and reduces cutting thrust\u003c\/li\u003e\n\u003cli\u003eStub screw machine length (1.875 inches OAL) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for standard CW-rotation spindles\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute screw machine length drill bit for use in screw machines, CNC machining centers, and bench drill presses accepting a straight 1\/8-inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDe-energize and lock out the machine spindle before changing tooling per OSHA lockout\/tagout requirements. Secure the straight shank firmly in a properly sized drill chuck and verify concentricity before resuming operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not have coolant-through capability. Inspect the split point for chipping or wear before each use and replace if the cutting edge is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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, Web-Thinned\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 74130196\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729315758386,"sku":"74130196","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b555567c85bbc1a2593f1d0cbaacc02a.jpg?v=1788702810","url":"https:\/\/voomisupply.com\/products\/hertel-74130196-screw-machine-drill-bit-1-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
