The bit measures 1.375 inches in diameter with a 0.500-inch straight-cylindrical shank, allowing it to chuck into standard 1\/2-inch drill chucks despite the larger cutting diameter. The 118-degree standard point angle is suited for drilling steel, aluminum, copper, and similar materials. Constructed from high speed steel with a bright uncoated finish, this Series R56 bit offers reliable performance across common shop and field drilling tasks. Total weight is 0.5 pounds.\u003c\/p\u003e\n\u003cp\u003eThis drill bit fits applications in mechanical, HVAC, plumbing, and electrical trade work where large-diameter holes are needed in ferrous metal, aluminum, copper, magnesium, nickel, titanium, and synthetic materials. The reduced shank design extends compatibility to standard 1\/2-inch chucks while the 3-inch flute length and 6-inch overall length give adequate reach for most structural and panel drilling situations. It is suited for right-hand rotation drills in both bench-press and handheld configurations for general production and maintenance use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.375-inch cutting diameter with 0.500-inch reduced straight-cylindrical shank for use in standard 1\/2-inch chucks\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose performance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect tolerance on precision holes\u003c\/li\u003e\n  \u003cli\u003e3-inch flute length with regular spiral for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length suits standard drilling depths in structural and panel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use reduced shank drill bit compatible with 1\/2-inch chuck capacity drills and drill presses.

Secure the shank fully into the chuck before drilling and verify chuck tightness to prevent slippage on large-diameter cuts. Use appropriate cutting fluid or coolant for extended run times in hard ferrous metals, though the bit is rated for dry cutting in general applications. Follow applicable shop safety practices including eye protection and secure workpiece fixturing before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Cermet, Copper, Magnesium, Nickel, Synthetic, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 5999908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722660839730,"sku":"5999908","price":239.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c8f2390608babec791fb737644b9b41.jpg?v=1788594197","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999908-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
