Manufactured from high speed steel with a steam oxide coating, it is designed for general purpose drilling across a wide range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The bit features a standard 118-degree point angle, a two-flute spiral configuration, and a web-thinned tapered web for improved chip evacuation. Overall length is 1.625 inches. Licensed tradespeople and machinists install these bits in standard drill chucks for precision hole work in fabrication, maintenance, and repair applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance drilling in metalworking environments where small-diameter, tight-tolerance holes are required. The straight-cylindrical shank fits standard drill chucks without modification. The regular spiral flute geometry and 118-degree point make it appropriate for general purpose work on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It belongs to Series R10-R15-R18 and conforms to ANSI standards, making it a reliable choice for shops that stock to specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 58 with a decimal diameter of 0.0420 inches for tight-tolerance small-hole work\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with steam oxide coating for wear resistance on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general purpose drilling across multiple material types\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust and improves chip clearance at the cutting tip\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design with a flute length of 0.6875 inches (11\/16 inch) and maximum drilling depth of 0.6875 inches\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank diameter of 0.0420 inches fits standard drill chucks; conforms to ANSI specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general purpose jobber length drill bit conforming to ANSI standards, suitable for use in standard drill chucks and drill presses rated for small-diameter wire gauge bits in the 0.0000 to 0.0500 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, toolroom technicians, and maintenance trades using standard drill chucks or collet holders rated for the shank diameter. Ensure the drill press or hand drill is powered off and secured before changing bits. Verify chuck jaw condition and clamping force to prevent slippage on the small-diameter straight shank. Do not exceed the maximum drilling depth of 0.6875 inches without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 0.6875 inches (11\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6875 inches (11\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Length\u003c\/strong\u003e: 0.9375 inches (15\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.625 inches (1-5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 16xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10-R15-R18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702100721970,"sku":"5999127","price":40.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2bbd17554f8298fe95bb319a732ccea_00c7841b-cb4c-47ef-aaea-47fb84d1fafc.jpg?v=1788409167","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999127-jobber-drill-bit-58-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
