Built to the HSCO135 series specification, it features a 135-degree split point that reduces walking on entry and allows drilling to start without a center punch in most applications. At 1-7\/8 inches overall length, this stub-length bit delivers added rigidity and reduced deflection compared to jobber-length equivalents. The right-hand cutting direction and two-flute regular spiral design produce consistent chip evacuation. This bit is sold individually and carries a minimum order quantity of 12 units.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production drilling and repair work in metal fabrication, machine shops, and general industrial maintenance. Its short overall length and stiff geometry make it a common choice for drill press work and CNC short-run operations where hole location accuracy matters. The wire gauge No. 34 size (0.1110 inches decimal) falls within the 0.1000 to 0.1500 inch diameter range, making it appropriate for small-diameter through-holes and pilot holes in ferrous and non-ferrous metals. A licensed machinist, tool and die tech, or industrial maintenance mechanic would typically select this bit for precision metal drilling applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and eliminates center-punch requirement on most surfaces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel web configuration improves chip clearance and reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 1-7\/8 inches OAL provides rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting with two-flute regular spiral for predictable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraw finish (heat-treated surface) typical of cobalt HSS tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production-use drill bit for applications requiring a No. 34 wire gauge diameter (0.1110 inches) in screw machine length cobalt construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this bit requires a drill press, CNC machine, or hand drill with a compatible straight-shank chuck rated for the 0.1110-inch shank diameter. Ensure the workpiece is firmly secured before drilling and use appropriate cutting fluid for ferrous metals to preserve tool life. Follow applicable shop safety standards and machine guarding requirements during operation. Inspect the cutting edges for wear before each use, as cobalt bits can chip if run at incorrect speeds or feeds for the material.\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. 34\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\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\u003eFlute Length\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1000 to 0.1500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 74130865\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740124119346,"sku":"74130865","price":42.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10e054cf9044301ccbda8e4eebc1aab4.jpg?v=1788822572","url":"https:\/\/voomisupply.com\/products\/hertel-74130865-cobalt-screw-machine-drill-bit-size-34","provider":"Voomi Supply","version":"1.0","type":"link"}
