It carries a 47\/64 inch (0.7344 inch) diameter with a 135-degree split point that reduces walking and lowers thrust at entry. The bit runs a regular right-hand spiral flute, measures 5 inches overall with a 3-1\/8 inch flute length, and features a straight cylindrical shank of the same 0.7344 inch diameter. Web thinning and a parallel web configuration help clear chips and reduce heat buildup in hard materials. This is a production-grade tool suited for machine shop and field metalworking applications.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for drilling stainless steel, superalloys, and other tough workpiece materials where high-speed steel bits lose edge quickly. The screw machine length format — shorter than jobber length — provides added rigidity in drill press, CNC, and turret lathe setups. It fits any spindle or chuck that accepts a straight shank at 0.7344 inches. The HSCO135 series designation identifies it as a heavy-duty cobalt split-point line, appropriate for production environments as well as maintenance and repair work where hole quality in hard metals matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e47\/64 inch diameter cobalt construction for drilling stainless steel and tough alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces drill walk and entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body adds rigidity over jobber length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute, 3-1\/8 inch flute length\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill press, CNC, and turret lathe chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct production substitute for any application requiring a straight-shank cobalt screw machine drill bit at 47\/64 inch diameter with a 135-degree split point geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or trade professionals familiar with metalworking equipment. Secure the straight shank fully in the chuck before operation and verify spindle speed is appropriate for cobalt tooling in the target material. Use cutting fluid or coolant when drilling stainless steel and tough alloys to extend edge life, even though this bit does not have through-coolant capability. Inspect the cutting edges before each use and replace if chipping or wear is visible.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 47\/64 inches (0.7344 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7344 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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 83240549\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750173081906,"sku":"83240549","price":98.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/286ae98839ebdf5bcc2c096f92392827.jpg?v=1788914051","url":"https:\/\/voomisupply.com\/products\/hertel-83240549-cobalt-screw-machine-drill-bit-47-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
