It carries a 118-degree standard point angle and a regular spiral flute pattern with web thinning for reduced thrust during entry. The straight-cylindrical shank measures 0.0595 inches in diameter and seats cleanly in standard drill chucks. Overall length is 1.875 inches with a flute length of 0.875 inches, yielding a 15xD flute-to-diameter ratio suited to general-purpose through-hole drilling. Machinists, maintenance technicians, and metal fabricators install this bit in handheld drills, drill presses, and CNC machines alike.\u003c\/p\u003e\u003cp\u003eThis bit is rated for drilling steel, cast iron, non-ferrous metals, and superalloys including titanium. It follows ANSI standards and belongs to the R10H-R18H series, placing it in the general-purpose performance tier appropriate for production and maintenance applications. Typical uses include pilot holes, through-holes, and clearance holes in sheet metal and structural stock where a No. 53 wire gauge diameter is called out on a print or assembly spec.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 53 diameter: 0.0595 inches for precise wire-gauge-spec hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design promotes chip evacuation in through-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks, no flat required\u003c\/li\u003e\n\u003cli\u003eANSI-compliant geometry; R10H-R18H series general-purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber length drill bit suitable for use in handheld power drills, benchtop drill presses, and CNC drilling applications calling for a wire gauge No. 53 diameter.

Apply appropriate cutting fluid or lubricant when drilling steel or superalloys to extend tool life and maintain hole quality. Always wear eye protection and secure the workpiece firmly before drilling. Inspect the bit for chipping or wear before each use; a damaged cutting edge should be replaced or resharpened before returning to service.\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. 53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0595 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.875 inches (1-7\/8 inches)\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: 0.0595 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.000 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: R10H-R18H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel; Cast Iron; Non-Ferrous Metal; Superalloys and Titanium\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: 5998035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698116198706,"sku":"5998035","price":48.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4691d72f892b92915254364cb4aea851_bb27a094-85ba-4333-af62-578dc37cdb85.jpg?v=1788357934","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998035-jobber-drill-bit-no-53","provider":"Voomi Supply","version":"1.0","type":"link"}
