It is ground from high speed steel with a bright, uncoated finish and features a standard 118-degree point angle with web thinning for easier entry. The two-flute spiral design provides a 9xD flute-to-diameter ratio, delivering efficient chip evacuation during general-purpose drilling. At 2.5 inches overall length with a 1.375-inch flute length, this bit is proportioned for hand drills, drill presses, and CNC drill cycles where a straight-cylindrical shank is required.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production and maintenance drilling in steel, stainless steel, cast iron, non-ferrous metals, and hard materials. Right-hand cut geometry is standard for conventional drilling operations in fabrication shops, machine shops, and field service environments. It carries ANSI standards compliance and belongs to the Series D33F-D33W-D33L-D33M family, making it a recognized production-grade option for shops that specify wire-gauge drill sets. A single-piece package quantity makes it straightforward to stock as a replacement or add to a working set.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 21 size — 0.1590 inches decimal diameter\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bright, uncoated finish\u003c\/li\u003e\n\u003cli\u003eRegular spiral, two-flute design — 1.375 inches maximum drilling depth\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank, 0.1590 inches diameter, 1.125 inches shank length\u003c\/li\u003e\n\u003cli\u003eRight-hand cut — compatible with conventional clockwise-rotation drilling\u003c\/li\u003e\n\u003cli\u003eANSI-compliant — Series D33F-D33W-D33L-D33M\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length replacement drill bit for use in standard drill chucks accepting straight-cylindrical shanks across hand drills, drill presses, and CNC drilling centers.

Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Select an appropriate cutting speed and feed rate for the target material — excessive feed pressure on hard materials can chip the point. Coolant-through operation is not supported on this bit; apply cutting fluid externally when drilling stainless steel or hard alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1590 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: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.375 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: 0.1590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 9xD\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\u003eTool Application\u003c\/strong\u003e: Drilling, General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: D33F-D33W-D33L-D33M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\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: 0.5 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: 6002473\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693398393138,"sku":"6002473","price":36.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/117b43f7ff038153da080e0769d44186_4c43bb16-2f73-43a0-96e1-41fd34d8d0af.jpg?v=1788311792","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6002473-jobber-drill-bit-no-21","provider":"Voomi Supply","version":"1.0","type":"link"}
