Built from cobalt tool steel and coated with TiAlN (titanium aluminum nitride), this bit handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel tooling. The 1\/16 inch diameter and 1-5\/8 inch overall length make it well-suited to tight-clearance drilling tasks on metal, stainless, and alloy workpieces. The 135-degree split point starts on contact without a center punch and reduces thrust load. Right-hand cutting with a regular spiral flute and straight-cylindrical shank for standard chuck mounting.\u003c\/p\u003e\u003cp\u003eScrew machine length bits are shorter than jobber-length equivalents, which reduces deflection and increases hole-location accuracy. This bit is used in production machining, maintenance shops, fabrication environments, and HVAC or electrical trade work where drilling into sheet metal, enclosures, or structural steel is routine. The 5\/8 inch flute length accommodates typical shallow-hole depths at this diameter. Its compact geometry is especially useful in drill presses and CNC setups with limited Z-axis travel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool steel construction for heat and wear resistance in harder materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life and reduces built-up edge at higher cutting speeds\u003c\/li\u003e\n\u003cli\u003e135-degree split point for self-starting, reduced thrust, and accurate hole entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web configuration reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute for efficient chip evacuation in through and blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard screw machine length drill bit with a straight-cylindrical shank, compatible with any drill press, hand drill, or CNC spindle chuck accepting 1\/16 inch round shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Use appropriate cutting fluid or lubricant when drilling stainless or alloy steel to extend tool life and improve hole finish. Disconnect or de-energize any equipment being drilled into before starting. Dispose of metal chips safely and inspect the cutting edge for wear before reuse.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5\/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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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\u003eFlute Type\u003c\/strong\u003e: Spiral (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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 74130121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730241716530,"sku":"74130121","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ead9955b843665d0cba7fc69394b640.jpg?v=1788713927","url":"https:\/\/voomisupply.com\/products\/hertel-74130121-screw-machine-drill-bit-1-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
