The 15\/32-inch cutting diameter pairs with a 3\/8-inch Weldon shank, allowing the bit to fit standard 3\/8-inch chucks despite its larger cutting head. The 135-degree split point reduces walking at startup and requires less feed pressure compared to a conventional 118-degree point. Overall length is 4-3\/4 inches with a 3-1\/8-inch flute length. The coated finish extends cutting life by reducing friction and heat buildup at the cutting edge. This bit is intended for right-hand rotation and is suited for machinists, millwrights, pipefitters, and maintenance technicians working with ferrous metals.\u003c\/p\u003e\u003cp\u003eThe BDNA-20946 is designed for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and tough alloy materials. The reduced shank design makes it practical when a larger diameter hole is needed but only a 3\/8-inch chuck is available. The Weldon shank with three flats resists slipping under torque, which is important when drilling tough alloys that require consistent feed pressure. This bit fits standard drill presses, magnetic drills, and hand drills equipped with a 3\/8-inch chuck. It is a general-purpose T8M series bit appropriate for production drilling and maintenance work across fabrication, HVAC, plumbing, and electrical rough-in applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/32-inch cutting diameter with 0.4688-inch decimal equivalent for precision layout reference\u003c\/li\u003e\n\u003cli\u003eWeldon shank with three flats prevents bit rotation and slippage under load\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and minimizes walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles carbon steel, cast iron, stainless steel, and tough alloys\u003c\/li\u003e\n\u003cli\u003eCoated finish reduces friction and extends cutting edge service life\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flutes clear chips efficiently during through-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose reduced shank drill bit compatible with 3\/8-inch Weldon-style chucks on drill presses, magnetic drill units, and hand-held electric drills.

Clamp or secure the workpiece to prevent movement during operation. Apply cutting fluid or coolant when drilling stainless steel or hard alloys to manage heat buildup, even though this bit is rated for dry cutting. Inspect the cutting edge for wear or chipping before each use and replace the bit if the point is damaged to prevent workpiece damage or bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/32 inch (0.4688 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eSeries\u003c\/strong\u003e: T8M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-20946\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51693385318706,"sku":"BDNA-20946","price":60.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39c128f3f153c85bd149f416269c59c1.jpg?v=1788311550","url":"https:\/\/voomisupply.com\/products\/import-bdna-20946-reduced-shank-drill-bit-15-32-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
