Built from cobalt tool steel with an oxide straw finish, this bit delivers the heat resistance and edge retention needed for demanding applications. It carries a 118-degree standard point angle and a right-hand cutting direction, making it compatible with conventional drill press and handheld drill setups. At 6 inches overall length with a 3-inch flute length, it provides adequate chip clearance for deep hole entry in metal fabrication and maintenance work.\u003c\/p\u003e\u003cp\u003eThis bit is suited for machinists, maintenance technicians, and fabricators working with stainless steel, alloy steels, and other tough high tensile strength materials. The straight-cylindrical 1\/2-inch shank seats securely in standard drill chucks without requiring a tapered spindle adapter. It is a practical choice for job-site drilling, machine shop work, and field maintenance applications where material hardness demands a cobalt-grade cutting tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool steel construction for high heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for accurate starting and general-purpose drilling\u003c\/li\u003e\n\u003cli\u003eOxide straw finish reduces friction and helps resist corrosion\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1\/2-inch shank fits standard 1\/2-inch drill chucks directly\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral fluting promotes efficient chip evacuation during drilling\u003c\/li\u003e\n\u003cli\u003e3-inch flute length supports a maximum drilling depth of 3 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for applications requiring a 1\/2-inch cobalt reduced shank bit with a 118-degree standard point, suitable for use in standard 1\/2-inch keyed or keyless drill chucks on drill presses and handheld drills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with metalworking drill procedures. Secure the shank fully in the chuck and verify it is tightened before operation. Always wear appropriate PPE including eye protection when drilling metal. Follow applicable shop safety standards and equipment manufacturer guidelines for speed and feed settings appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: Oxide Straw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Tough High Tensile Strength Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 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: 74147380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743910101298,"sku":"74147380","price":106.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2758fbd292a81e29914caad66745c61.jpg?v=1788851132","url":"https:\/\/voomisupply.com\/products\/hertel-74147380-cobalt-drill-bit-1-2-inch-118-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
