It features a 135-degree split point that self-centers on contact, reducing walking on hard or smooth surfaces. The bit has a 0.136-inch diameter, an overall length of 2.875 inches, and a flute length of 1.75 inches. A regular spiral flute with web-thinned, tapered web geometry promotes efficient chip evacuation. This is a general-purpose right-hand cutting bit used by machinists, pipefitters, electricians, and maintenance mechanics for production and repair drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe 5997004 is suited for drilling steel, aluminum, and other non-ferrous metals in general shop and field applications. The straight cylindrical shank seats directly in standard drill chucks without requiring collets or adapters. At 2.875 inches overall, it fits cordless and corded drill drivers, drill presses, and hand-held right-angle drills commonly used in mechanical and electrical trade work. The QC21P series targets general-purpose performance across a broad range of base metals and light alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 29 wire size, 0.136-inch diameter — matches standard wire-gauge drill charts for tap and clearance hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers and reduces thrust force compared to 118-degree conventional points\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and heat resistance for metal drilling\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for use with or without cutting fluid\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute with 13xD flute-to-diameter ratio for efficient chip evacuation in through-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose jobber drill bit compatible with standard 3-jaw drill chucks accepting straight cylindrical shanks at 0.136 inches in diameter.

Secure the workpiece with a vise or clamp — never hand-hold metal stock when drilling. Apply a suitable cutting fluid when drilling steel to extend bit life and reduce heat buildup. Inspect the cutting edges and point for wear before each use; a dull or chipped point increases thrust load and can cause bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 29\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.136 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 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\u003eShank Diameter\u003c\/strong\u003e: 0.136 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: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\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: 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Aluminum, Non-Ferrous Metals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.042 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 5997004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723883741490,"sku":"5997004","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434_39562114-70fb-4bd5-b07f-45252328d6ab.jpg?v=1788609311","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997004-no-29-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
