Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree standard point angle with web thinning for improved chip clearance and reduced thrust at entry. It is sized at 15\/64 inches (0.2344 inches) in diameter with a straight shank of the same diameter. The left-hand cutting direction makes it well-suited for extracting broken fasteners and reverse-drilling applications. Machinists, maintenance technicians, and trade professionals working with drill presses or hand drills will find this a reliable general-purpose option.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use on steel and cast iron workpieces in general-purpose machining and fabrication environments. Its jobber-length profile offers a practical balance between reach and rigidity for common drilling tasks. The 2-flute regular spiral flute geometry promotes efficient chip evacuation during through-hole and blind-hole drilling. The Series L10 designation places it within a standardized line of jobber-length HSS drill bits conforming to ANSI specifications, making it appropriate for use in both shop and field maintenance settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cut direction for reverse-rotation drilling and broken fastener extraction\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHSS construction with bright, uncoated finish suitable for general-purpose ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute geometry for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight shank at 0.2344 inches for compatibility with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards under Series L10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 15\/64-inch straight shank.

Before use, ensure the workpiece is securely clamped and the machine is powered down while loading or changing bits. Because this is a left-hand cut bit, it must be used with a spindle rotating in reverse (counterclockwise) direction. Apply appropriate cutting fluid when drilling ferrous materials to extend tool life and maintain dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 15\/64 inches (0.2344 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\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\u003eCutting Direction\u003c\/strong\u003e: Left Hand\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: 2-5\/8 inches (2.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches (3.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/64 inches (0.2344 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2-5\/8 inches (2.6250 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: L10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 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: 5995470\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693216366898,"sku":"5995470","price":23.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/700097b531762e7d1f9969c9cacad3be_ded3f451-0dec-418c-90b9-5c114b71e015.jpg?v=1788309110","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995470-jobber-drill-bit-15-64","provider":"Voomi Supply","version":"1.0","type":"link"}
