Built from high-speed steel (HSS) with a bright, uncoated finish, it features a 118-degree standard point angle and a web-thinned, tapered web configuration for improved chip clearance and reduced thrust at entry. The straight shank measures 0.5000 inches in diameter, and the overall length is 6 inches. Two regular spiral flutes run 4.5 inches to support consistent chip evacuation. This bit belongs to the Series L10 line and meets ANSI standards. It is a general-purpose tool suited for machinists, maintenance technicians, and trade professionals working with metal substrates.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for left-hand drilling applications, which makes it particularly useful when removing broken fasteners or reverse-threading operations. It performs in general-purpose drilling of steel and cast iron in both production and field maintenance environments. The 9xD flute-to-diameter ratio provides adequate depth capacity for most through-hole and blind-hole jobber-length tasks. No coolant-through capability is present, so external cooling or cutting fluid should be applied when drilling harder or thicker stock at sustained feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting 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 rated for steel and cast iron\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design with 4.5-inch flute length for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight shank at 0.5000 inches diameter for use in standard drill chucks\u003c\/li\u003e\n\u003cli\u003eANSI-compliant Series L10 general-purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length replacement or add-stock bit compatible with any standard drill chuck accepting a 0.5000-inch straight shank.

Confirm the drilling machine supports left-hand or reverse rotation before use, as standard forward-rotation machines will not cut with this bit. Secure the workpiece firmly before drilling, and apply cutting fluid when working with ferrous materials to extend tool life and reduce heat buildup. Do not exceed the rated maximum drilling depth of 4.5 inches per pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\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: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: L10\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: 1.3 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: 5995602\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51710891884850,"sku":"5995602","price":66.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/700097b531762e7d1f9969c9cacad3be_78686387-5d12-49a5-9c88-b49ec85b073b.jpg?v=1788471953","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995602-1-2-inch-hss-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
