Built to Series HSCO135 standards, it features a 135-degree split point that reduces walking and allows drilling without a center punch on most surfaces. The web-thinned, parallel web construction reduces thrust load and improves chip evacuation. At 2-3\/16 inches overall length, this stub-style bit fits low-clearance drilling setups where standard length bits cannot reach. It is suited for machinists, tool-and-die workers, maintenance technicians, and fabricators working with drill presses, CNC machines, or hand-held power tools.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for precision-tolerance drilling applications where a wire gauge Size 13 hole at 0.1850 inch decimal diameter is required. The short overall length and straight cylindrical shank make it compatible with standard drill chucks and collet holders. Typical applications include screw machine production work, fixture fabrication, and close-tolerance hole drilling in steel, stainless steel, cast iron, and other hard alloys. The right-hand cutting direction and regular spiral flute geometry suit general-purpose through-hole and blind-hole drilling in shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction provides increased heat and wear resistance compared to standard HSS bits\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and lowers required feed pressure\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web design improves chip flow and reduces thrust load\u003c\/li\u003e\n  \u003cli\u003eScrew machine length at 2-3\/16 inches overall allows use in confined or low-clearance setups\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet systems without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for general drilling in hard and abrasive materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for Size 13 wire gauge screw machine length drill bits with a 0.1850 inch diameter and straight shank, compatible with any standard drill chuck or collet holder accepting that shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed and serviced by machinists, tool crib personnel, or maintenance technicians using standard drill press or CNC tooling procedures. Ensure the machine spindle is at a full stop and the chuck or collet is fully released before inserting or removing the bit. Secure the shank with adequate clamping force to prevent slippage under load. Use appropriate cutting fluid for the material being drilled to extend tool life and maintain hole tolerance.\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: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1850 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\u003eOverall Length\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/8 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\u003eSeries\u003c\/strong\u003e: HSCO135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\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: 74130642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743419760946,"sku":"74130642","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c79088768eb4926169624d576cdc552b.jpg?v=1788846854","url":"https:\/\/voomisupply.com\/products\/hertel-74130642-cobalt-screw-machine-drill-bit-size-13","provider":"Voomi Supply","version":"1.0","type":"link"}
