Built to the HSCO135 series standard, it features a 135-degree split point that reduces walking on entry and decreases thrust required to start the cut. The straight cylindrical shank measures 0.5781 inches in diameter, and the overall length is 4-1\/8 inches, making it a compact, rigid choice for close-quarter or machine-mounted applications. Web thinning further reduces cutting resistance in hard materials. This bit is sold individually and suited for use in drill presses, CNC machines, and production environments where tool integrity matters.\u003c\/p\u003e\n\u003cp\u003eThis bit is primarily intended for drilling stainless steel and other tough alloys in industrial, maintenance, and fabrication settings. Screw machine length geometry provides added rigidity compared to jobber-length bits, reducing deflection in harder substrates. It is well suited for machine shop use, HVAC equipment fabrication, plumbing rough-in through structural steel, and similar trade applications where conventional high-speed steel bits wear prematurely. The 2-flute regular spiral flute design promotes consistent chip evacuation during through-hole drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for extended tool life in stainless steel and tough alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry walking and lowers required thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web configuration for reduced cutting resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body provides superior rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with regular spiral flute for reliable chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for screw machine length cobalt drill bits in the 0.5000 to 0.6000 inch decimal inch size range, fitting standard drill chucks and collet systems that accept a 0.5781-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed and serviced by machinists, tool-and-die professionals, and trade technicians operating drill presses or CNC equipment. Secure the shank fully in the chuck or collet before operation and verify runout before beginning production drilling. Use appropriate cutting fluid or coolant when drilling stainless steel to manage heat buildup and extend tool life. Inspect the cutting edges for wear before each use and replace when the split point or flute edges show signs of deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 37\/64 inches (0.5781 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5781 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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Tough Alloy\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 Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 83240499\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729138188594,"sku":"83240499","price":71.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/204cb422432a43af8a23263d88e07f20.jpg?v=1788700685","url":"https:\/\/voomisupply.com\/products\/hertel-83240499-cobalt-screw-machine-drill-bit-37-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
