Built from cobalt high-speed steel with a titanium aluminum nitride (TiAlN) coating, it delivers extended tool life in hard and abrasive materials including stainless steel, cast iron, and high-alloy steels. The 135-degree split point reduces walking and decreases thrust force at entry, allowing faster starts without a center punch on most materials. Overall length is 2-3\/16 inches with a flute length of 1-1\/8 inches, making it well suited for screw machine and short-reach drilling setups. The straight cylindrical shank fits standard drill chucks without adapters.\u003c\/p\u003e\u003cp\u003eThis bit is used in production drilling, job shop machining, and maintenance-repair operations where tool life and hole quality in tough materials are priorities. The screw machine length format  -  shorter than jobber length  -  provides greater rigidity and reduced deflection, especially when drilling stainless steel, hardened alloys, or other work-hardening materials. It is appropriate for use in CNC machining centers, turret lathes, drill presses, and screw machines. Machinists, tool-and-die makers, and maintenance technicians are the primary installers and operators.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction resists heat buildup in hard and work-hardening metals\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends cutting life and reduces friction at elevated temperatures\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and lowers required entry thrust\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web improves chip evacuation and cutting efficiency\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides added rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute, straight cylindrical shank for direct chuck mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or production-use drill bit for standard straight-shank drill chucks across CNC machining centers, drill presses, turret lathes, and screw machines requiring a wire size 14 (0.1820 inch) cutting diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety. Ensure the machine spindle is fully stopped and the chuck is secure before inserting or removing the bit. Use appropriate cutting fluid or coolant where the machine setup permits to maximize tool life, particularly when drilling stainless or alloy steels. Inspect the cutting edge and coating for wear or chipping before each use and replace when performance degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1820 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: Spiral\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.16 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: 74132119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742870143282,"sku":"74132119","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/157e016e6ae4831e2d382c4dcb109519.jpg?v=1788840052","url":"https:\/\/voomisupply.com\/products\/hertel-74132119-screw-machine-drill-bit-size-14-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
