It is manufactured from high speed steel (HSS) with a bright, uncoated finish and measures 1-5\/8 inches overall length. The bit carries a 118-degree standard point angle with a web-thinned, tapered web configuration that reduces thrust at entry and improves chip clearing. The spiral flute design and right-hand cut make it compatible with standard drill presses, hand drills, and machining center setups. Metalworking shops, maintenance technicians, and fabricators routinely stock wire gauge bits in this size range for close-tolerance hole work.\u003c\/p\u003e\u003cp\u003eThis bit is sized to wire gauge number 58, equivalent to 0.0420 inches decimal diameter. It is suited for light-duty applications requiring small-diameter holes where precision fit matters, such as pilot holes, instrument panel work, printed circuit board fixturing, and sheet metal fabrication. The straight-cylindrical shank seats securely in standard drill chucks and collets. The regular spiral type and two-flute geometry provide efficient chip evacuation in shallow-to-moderate depth holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 58, 0.0420 inches decimal diameter for close-tolerance drilling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for general-purpose metal, wood, and plastic applications\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish with regular spiral, two-flute geometry for clean chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 11\/16-inch flute length in a compact 1-5\/8-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit suitable for standard drill chucks and collets accepting a 0.0420-inch straight-cylindrical shank across drill presses, hand drills, and CNC machining setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this bit should be performed by qualified machinists or technicians familiar with small-diameter tooling. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits, as small-diameter bits are susceptible to deflection and breakage under side load. Power down and de-energize all equipment before changing tooling. Use appropriate cutting fluid or dry cutting technique per the workpiece material to extend tool life and maintain hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 58\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0420 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0420 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 Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eMaterial\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 Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 84578137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733286388018,"sku":"84578137","price":37.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c54d08a8600dde6ec751918f59393e06.jpg?v=1788753589","url":"https:\/\/voomisupply.com\/products\/hertel-84578137-jobber-drill-bit-wire-58-hss-118","provider":"Voomi Supply","version":"1.0","type":"link"}
