Built from high speed steel with an oxide coating, it delivers reliable performance across a range of common drilling tasks. The bit measures 21\/64 inch (0.3281 inch decimal) in diameter with a 118-degree standard point angle, a right-hand spiral flute configuration, and a straight-cylindrical shank. Overall length is 4-5\/8 inches with a flute length of 3-5\/16 inches. The web-thinned, tapered web design reduces thrust and improves chip evacuation during cutting. This bit is typically installed and used by machinists, maintenance technicians, and HVAC or plumbing tradespeople requiring precision hole starts in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThe 71205801 suits production and maintenance drilling in metal fabrication shops, mechanical rooms, and field service environments. The regular spiral flute handles standard drilling in mild steel, aluminum, and similar materials. With a shank diameter matching the bit diameter at 21\/64 inch, it seats securely in most 3-jaw drill chucks and keyed chuck systems. The oxide finish provides a degree of lubricity and corrosion resistance that extends service life in moderate-duty applications. This bit ships individually but requires a minimum order of 6 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e21\/64 inch diameter with 0.3281 inch decimal equivalent for precise sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for clean entry in general-purpose materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles drilling in mild steel, aluminum, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eOxide coating provides lubricity and basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard 3-jaw keyed or keyless drill chucks accepting a straight-cylindrical shank in the 21\/64 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank fully in the drill chuck before operation and verify the chuck is tightened evenly to prevent runout. Use appropriate cutting fluid or lubricant when drilling ferrous materials to manage heat and extend bit life. Always wear appropriate eye protection and secure the workpiece to prevent movement during drilling. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is degraded.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/64 inch (0.3281 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 21\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\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, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.485 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: 71205801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753865806130,"sku":"71205801","price":40.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02a283151920bd1d595a145a72081d28.jpg?v=1788941633","url":"https:\/\/voomisupply.com\/products\/hertel-71205801-jobber-drill-bit-21-64-in-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
