Built from high speed steel (HSS) with a bright, uncoated finish, this bit features a 1-1\/32 inch (1.0312 inch decimal) cutting diameter paired with a reduced 1\/2 inch Weldon shank, allowing it to seat in standard 1\/2 inch chuck equipment despite the oversized cutting head. The 118-degree standard point angle is suited to a broad range of ferrous and non-ferrous materials. Overall length is 6 inches with a 3 inch flute length and a maximum drilling depth of 3 inches. The part weighs approximately 0.5 pounds.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use on ferrous metals as its primary workpiece material, with rated secondary compatibility covering aluminum, copper, magnesium, nickel, titanium, synthetic materials, and cermet. The reduced shank design makes it practical on job sites where only 1\/2 inch drill presses, magnetic drills, or hand drills are available, yet a larger bore diameter is required. It is a solid choice for HVAC fabricators, plumbers, pipefitters, electricians, and general contractors who need to drill large-diameter holes in sheet metal, angle iron, pipe hangers, or structural steel without upgrading to a larger chuck capacity. Series R57 follows ANSI standards. Sold individually with a minimum order quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced 1\/2 inch Weldon shank fits standard chucks while cutting a 1-1\/32 inch diameter bore\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry and hole quality\u003c\/li\u003e\n  \u003cli\u003eThree-flat Weldon shank prevents bit slippage under torque load\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to chip or flake; suitable for re-sharpening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2 inch chuck drill presses, magnetic drills, and hand drill equipment.

Always wear eye protection and clamp or secure the workpiece before drilling. Use cutting fluid on hard ferrous stock to extend bit life and maintain bore quality. Inspect the cutting edge before each use and replace or resharpen the bit if the edge is chipped or dull.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-1\/32 inches (1.0312 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\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\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\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\u003eShank Type\u003c\/strong\u003e: Weldon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\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\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R57\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: 5999545\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51714633892146,"sku":"5999545","price":137.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed3bbd25fb7b7f24cf32d7602997282e.jpg?v=1788504185","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999545-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
