Built from high-speed steel with a bright uncoated finish, it features a 135-degree split point that reduces walking and improves hole entry on hard surfaces. The parabolic spiral flute design promotes efficient chip evacuation, reducing heat buildup during extended drilling cycles. With an overall length of 5.625 inches and a cutting diameter of 29\/64 inch (0.4531 inch), this bit suits production and maintenance drilling tasks performed by machinists, pipefitters, and mechanical contractors working with ferrous and non-ferrous stock.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard drill chucks via its straight cylindrical shank and is compatible with benchtop drill presses, magnetic-base drills, and hand-held electric drills used in fabrication shops and field service applications. The Series QC21P designation places it in a heavy-duty general-purpose line built to ANSI standards. It is sold individually and is a practical choice for single-hole jobs or restocking tooling kits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces bit walking and improves penetration on hard surfaces\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, and titanium\u003c\/li\u003e\n\u003cli\u003eParabolic spiral flute promotes fast chip evacuation and reduced heat in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers thrust requirements and extends bit life\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eBuilt to ANSI standards under Series QC21P heavy-duty designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard 3-jaw drill chucks accepting a 29\/64 inch straight cylindrical shank, suitable for benchtop and portable drilling equipment used across metalworking, fabrication, and mechanical trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tradespeople familiar with metal-cutting operations. Secure the workpiece and ensure the drill chuck is fully tightened before operation. Apply appropriate cutting fluid when drilling stainless steel, cast iron, or titanium to reduce heat and extend bit life. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 29\/64 inch (0.4531 inch)\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: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4531 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Parabolic (Regular)\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys, Titanium\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, Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QC21P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5996893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51714317451570,"sku":"5996893","price":42.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434_bad1000d-02ca-415a-b91c-02332beedf60.jpg?v=1788499401","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996893-jobber-drill-bit-29-64","provider":"Voomi Supply","version":"1.0","type":"link"}
