It measures 15\/64 inch (0.2344 inch decimal) in diameter with an overall length of 3-7\/8 inches and a flute length of 2-5\/8 inches. The 135-degree split point reduces walking on entry and requires less thrust than a standard 118-degree point. Constructed from high speed steel with a bright uncoated finish, this bit suits production drilling and maintenance work across fabrication, HVAC, plumbing, and electrical trades where standard HSS performance is required.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for drilling steel, aluminum, and other non-ferrous materials in general workshop and field applications. The straight cylindrical shank fits standard three-jaw drill chucks on corded and cordless drills as well as drill presses. With an 11xD flute-to-diameter ratio, it clears chips efficiently in through-hole and moderate-depth drilling tasks. The QC21P series is a general-purpose line intended for everyday production and maintenance drilling where coated or specialty bits are not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree web-thinned split point reduces drill walking and lowers required feed pressure\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across steel and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for general-purpose use without added coating cost\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation during drilling\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for jobber-length drill bit geometry and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard three-jaw drill chuck accepting a 15\/64 inch (0.2344 inch) straight shank.

Ensure the workpiece is clamped or secured to prevent movement during drilling. Apply appropriate cutting fluid when drilling steel to extend bit life and improve hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/64 inch (0.2344 inch)\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: 3-7\/8 inches (3.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-5\/8 inches (2.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/64 inch (0.2344 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/4 inches (1.25 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: 2-5\/8 inches (2.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Aluminum, Non-Ferrous\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: 5997128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709332128050,"sku":"5997128","price":16.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14c3de90969c6378087aaa7d157a7434_c7038dfd-5dba-40be-99c9-3c192bc03d36.jpg?v=1788454759","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997128-15-64-in-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
