Manufactured from high speed steel with a bright uncoated finish, this bit features a 118-degree standard point angle, a spiral regular flute configuration, and a web-thinned tapered web for improved chip evacuation and point penetration. It carries a straight-cylindrical shank of 0.0280 inches in diameter and is designed for right-hand cutting. The 2-flute spiral design supports general-purpose drilling in a wide range of materials. Machinists, tool and die technicians, and maintenance mechanics are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general-purpose applications in production machining, maintenance operations, and precision hole-making where small-diameter wire gauge bits are required. The No. 70 wire gauge size is commonly specified for light materials including aluminum, brass, mild steel, and plastics where tight tolerance holes are needed for tapping, pinning, or fine-detail work. With a flute length of 3\/8 inches and a compact 1.25-inch overall length, it fits standard drill chucks and micro drill presses used in bench-top and CNC setups alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 70 size with 0.0280-inch decimal diameter for precision small-hole work\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for general-purpose durability across common workpiece materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tapered web for clean entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — suitable for dry drilling or use with cutting fluid\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip clearance in shallow holes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without special collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in any standard drill chuck or collet accepting a 0.0280-inch straight-cylindrical shank, including bench drill presses, CNC machining centers, and handheld drill motors.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and removal should be performed with the machine powered down and the spindle fully stopped. Secure the straight shank firmly in the chuck and verify concentricity before running. High speed steel bits perform best at appropriate cutting speeds for the workpiece material — running too fast in hard materials will reduce tool life. Eye protection and appropriate chip guards should be used per shop safety standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0280 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0280 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 84578251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734749446450,"sku":"84578251","price":43.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e3535781bba3c1097df9fe6f447c69d.jpg?v=1788766572","url":"https:\/\/voomisupply.com\/products\/hertel-84578251-jobber-drill-bit-size-70-hss-0-0280-in","provider":"Voomi Supply","version":"1.0","type":"link"}
