It features a 63\/64 inch (0.9844 inch decimal) cutting diameter paired with a 1\/2 inch Weldon shank, allowing it to seat securely in standard 1\/2 inch chuck toolholding without the need for a larger spindle bore. The 118-degree standard point angle is a proven general-purpose geometry suitable for a wide range of materials and drill press or milling machine applications. This bit is manufactured from high speed steel with a bright, uncoated finish and belongs to the Series R57 line.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for machine shop, maintenance, and fabrication environments where a large-diameter hole must be drilled using a 1\/2 inch capacity chuck or collet. The reduced shank design makes it practical for benchtop drill presses, knee mills, and portable magnetic drills that cannot accommodate a full 63\/64 inch shank. With a 3 inch flute length and 6 inch overall length, it handles moderate drilling depths in structural steel, plate, bar stock, aluminum extrusions, copper, and similar materials. It is a right-hand cut tool intended for conventional clockwise spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e63\/64 inch cutting diameter (0.9844 inch decimal) with a reduced 1\/2 inch Weldon shank for use in standard 1\/2 inch toolholding\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry and centering across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWeldon shank with 3 flats resists slippage under torque loads common at large drill diameters\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length with 3 inch flute length supports drilling depths up to 3 inches\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — compatible with cutting fluid application for extended tool life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with 1\/2 inch capacity drill chucks, Weldon-style end mill holders, and side-lock toolholding systems on drill presses, milling machines, and magnetic base drills.

Secure the workpiece fully before drilling and apply a cutting fluid appropriate for the workpiece material when drilling ferrous metals to manage heat and extend tool life. Inspect the cutting edges for chipping or wear before each use, particularly when working with hard ferrous alloys.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 63\/64 inch (0.9844 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: No (cutting fluid applied externally)\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: 6000041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698272928050,"sku":"6000041","price":130.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcf9b7890c2bd71f3dc51ad0922f04d4.jpg?v=1788360283","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000041-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
