Built from cobalt steel and finished with a TiAlN coating, this bit handles elevated cutting temperatures better than standard high-speed steel tooling. The 135-degree split point reduces walking and lowers thrust requirements at entry, making it well-suited for production drilling without a center punch. At 1-13\/16 inches overall length with a 13\/16-inch flute, the stub-length geometry increases rigidity and reduces deflection in short-reach applications. The straight cylindrical shank seats in standard drill chucks without additional adapters.\u003c\/p\u003e\u003cp\u003eThis bit is used in machine shop, fabrication, and maintenance applications where hole accuracy and tool life in harder workpieces are priorities. Screw machine length bits are a common choice for drill press, CNC, and turret lathe setups where a shorter, stiffer tool outperforms jobber-length alternatives. Machinists and toolroom technicians working with stainless steel, alloy steel, cast iron, and similar materials select cobalt TiAlN tooling for its extended wear resistance under continuous cutting loads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material resists heat buildup during high-speed or dry drilling operations\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in abrasive and hard workpiece materials\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and lowers required feed pressure\u003c\/li\u003e\n\u003cli\u003eStub screw machine length increases rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web configuration maintains cutting efficiency as the bit wears\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute clears chips efficiently in through-hole and blind-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 7\/64-inch screw machine length drill bits used in standard drill chucks accepting straight cylindrical shanks across drill press, CNC, and manual lathe turret applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine fully powered down and the spindle at rest. Secure the straight cylindrical shank fully within the chuck jaws and tighten evenly to prevent runout. Verify chuck capacity accommodates a 7\/64-inch shank before seating the bit. Use appropriate cutting fluid or cooling strategy for the workpiece material to maximize coating life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/64 inches (0.1094 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 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\/Finish\u003c\/strong\u003e: TiAlN\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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 Web-Thinned\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: 0.1000 to 0.1500 inches decimal\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: 0.01 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: 74131400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739785298226,"sku":"74131400","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c1977f6cc01df80b10d015e28b59192.jpg?v=1788818833","url":"https:\/\/voomisupply.com\/products\/hertel-74131400-screw-machine-drill-bit-7-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
