It features a 135-degree split point that reduces walking on contact and allows drilling to start without a center punch in most applications. The flute is spiral-cut in a right-hand direction with a regular helix, and the straight cylindrical shank seats directly in standard three-jaw chucks. Overall length is 3.125 inches with a 2-inch flute length. The cobalt steel construction handles harder workpiece materials that would accelerate wear on standard high-speed steel bits. An oxide finish provides additional surface hardness and corrosion resistance. This is a heavy-duty grade bit suited for production and service work.\u003c\/p\u003e\u003cp\u003eThe 04138707 is a general-purpose holemaking tool sized for applications requiring a 0.154-inch diameter hole, including tapping prep for small fasteners and precision clearance holes in steel, stainless, cast iron, and hard alloys. The heavy-duty cobalt grade makes it appropriate for metalworking environments where heat buildup is a concern, such as continuous drilling in thick plate or work on work-hardening materials. Machinists, maintenance technicians, and trade professionals working with drill presses or handheld power tools will find this bit fits standard chuck sizes without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction resists heat and wear during drilling in hard or abrasive metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates walking on entry\u003c\/li\u003e\n\u003cli\u003eOxide finish adds surface hardness and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design reduces cutting resistance\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard three-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit compatible with any three-jaw drill chuck or collet system that accepts a 0.154-inch straight cylindrical shank, including benchtop drill presses and handheld power drills used in metal fabrication and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the chuck and verify concentricity before drilling. Always power down and de-energize any drill press or tool before changing bits. Use cutting fluid or coolant when drilling hard alloys to extend bit life, even though this bit does not support coolant-through delivery. Wear appropriate eye protection per shop safety requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 23\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1540 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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\u003eFlute Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1540 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Tapered\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: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: 04138707\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746469871922,"sku":"04138707","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d060c04f45b3031c24074591d1848d2.jpg?v=1788870593","url":"https:\/\/voomisupply.com\/products\/hertel-04138707-cobalt-jobber-drill-bit-no-23-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
