Built from high-speed cobalt steel (HSCO) with a 135-degree split point, this bit reduces walking on entry and generates less heat when cutting hard materials. The 5\/8-inch diameter and shortened overall length of 4.25 inches make it suited for confined-clearance drilling on manual lathes, drill presses, and CNC setups. A web-thinned, parallel web configuration lowers thrust requirements and improves chip evacuation through the regular spiral flutes.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are a standard choice in metalworking shops, maintenance departments, and field service environments where drill depth is limited or rigidity is critical. This bit is appropriate for drilling stainless steel, heat-treated alloys, and other materials that generate significant tool wear. It is commonly used by machinists, pipefitters, and mechanical contractors when standard jobber-length bits flex too much or when working inside enclosures and tight frames. The right-hand cutting direction and straight cylindrical shank allow direct chucking in standard 3-jaw drill chucks and collet holders without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt (HSCO) construction handles stainless steel and tough alloys without premature edge wear\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces center-walking and lowers required thrust at entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web improves chip flow and reduces heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 4.25 inches overall provides greater rigidity than jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRegular spiral flutes with 2.75-inch flute length clear chips efficiently in through-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet systems without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit cobalt drill bit for use in any drill press, lathe tailstock, or CNC machine tool equipped with a straight-shank chuck or collet sized for a 5\/8-inch diameter shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eEnsure the drill press or machine tool spindle is fully stopped and de-energized before installing or removing the bit from the chuck. Secure the straight shank firmly in the chuck jaws and verify runout before beginning the cut. Use appropriate cutting fluid or coolant for stainless steel and tough alloy workpieces to extend tool life, as this bit does not support through-coolant delivery. Wear approved eye protection and follow applicable OSHA machine guarding requirements during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 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 (HSCO)\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 Spiral\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: HSCO135\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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: 74130493\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746355314994,"sku":"74130493","price":68.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a110cdfc1cc67642691877a6ebf28d3.jpg?v=1788868847","url":"https:\/\/voomisupply.com\/products\/hertel-74130493-cobalt-drill-bit-5-8-inches-135-degree-split-point","provider":"Voomi Supply","version":"1.0","type":"link"}
