It is machined from high-speed steel (HSS) with a bright, uncoated finish and a standard 118-degree point angle. The left-hand cutting direction makes this bit particularly useful for removing broken fasteners and reverse-extraction applications. With a straight shank measuring 19\/64 inch in diameter and an overall length of 4.375 inches, it fits standard drill chucks and is part of the Series L10 general-purpose line. Licensed tradespeople and machinists in HVAC, plumbing, and mechanical service work commonly reach for this bit when drilling into ferrous base materials.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling operations in steel and cast iron workpieces across residential and commercial service applications. The left-hand spiral flute aids in chip evacuation during reverse-rotation drilling, which is the primary reason technicians select this configuration when extracting seized or broken bolts. The 10xD flute-to-diameter ratio and tapered web configuration with web thinning support cleaner entry and reduced thrust requirements in typical shop and field use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cut direction for broken fastener extraction and reverse-rotation drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for use in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eHSS construction with bright uncoated finish for general-purpose durability\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design reduces drilling thrust and improves chip flow\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 2-flute configuration for balanced chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for general-purpose drilling in steel and cast iron workpieces.

Secure the shank fully in the chuck before operation and verify the drill is set to reverse rotation when using the left-hand cut for fastener extraction. Keep cutting speeds appropriate for HSS tooling in ferrous materials to avoid overheating, which can soften the tool steel. No coolant-through capability is present on this bit, so external lubrication is recommended when drilling deeper holes in steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/64 inch (0.2969 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\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: 3.0625 inches (3-1\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.375 inches (4-3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2969 inch (19\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (1-5\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.0625 inches (3-1\/16 inch)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: L10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\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\u003eWeight\u003c\/strong\u003e: 0.71 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: 5995472\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702457073970,"sku":"5995472","price":28.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/700097b531762e7d1f9969c9cacad3be_47b3891c-5e05-419e-9446-3c9ca2f19a04.jpg?v=1788410954","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995472-jobber-drill-bit-19-64","provider":"Voomi Supply","version":"1.0","type":"link"}
