Ground from cobalt high-speed steel and coated with TiAlN, this bit handles elevated cutting temperatures without breaking down. The 135-degree split point starts on contact, reducing walking and the need for a center punch. At 0.0700 inches in diameter (wire gauge size 50) and a compact 1-11\/16 inches overall length, it is sized for short-reach applications in drill presses, CNC machines, and hand-held power tools where a jobber-length bit would flex or deflect. Machinists, tool-and-die technicians, and production drillers turn to this geometry for tight-tolerance work in steel, stainless, and cast iron.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for screw machine and production drilling environments where short overall length controls deflection in deep or high-volume hole operations. The regular spiral flute with a 11\/16-inch flute length evacuates chips efficiently in short-depth bores. The straight cylindrical shank seats in standard drill chucks and collets without modification. Typical applications include secondary machining operations, fixture drilling, and component fabrication in both job shop and production floor settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction resists heat buildup during aggressive metal cutting\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and self-centers on entry\u003c\/li\u003e\n\u003cli\u003eScrew machine length body limits deflection in short-reach and high-speed drilling setups\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web configuration improves chip flow and cutting efficiency\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting spiral flute compatible with standard drill press and CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or production-use drill bit for standard drill chucks and collets accepting a straight cylindrical shank in the size 50 wire gauge diameter range of 0.0700 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists or qualified trade personnel familiar with rotating cutting tools. Secure the shank fully in the chuck or collet before operation and verify runout before high-speed use. Power down and de-energize the machine spindle completely before changing or inspecting the bit. Do not exceed the recommended cutting speed for the workpiece material, and use appropriate cutting fluid where the material and setup call for it.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 74132481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741550018866,"sku":"74132481","price":43.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5e16eb3dfddd06f1147f5aec12c24ab.jpg?v=1788832127","url":"https:\/\/voomisupply.com\/products\/hertel-74132481-screw-machine-drill-bit-size-50-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
