It measures 43\/64 inch (0.6719 inch) in diameter with a 1\/2 inch straight-cylindrical shank, allowing it to fit standard 1\/2 inch chucks while drilling larger-diameter holes. The bit runs 6 inches overall with a 3 inch flute length and features a 118-degree split point for fast, self-centering starts on ferrous and non-ferrous metals. Bright, uncoated cobalt construction provides heat resistance for tough materials without the need for a coating. Cutting direction is right-hand, and the spiral flute type is regular. This bit is part of the R56CO series and weighs approximately 0.5 pounds.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production and maintenance drilling in ferrous metals as the primary target material. Secondary compatible workpiece materials include aluminum, cermet, copper, magnesium, nickel, synthetic materials, and titanium. The reduced shank design is a practical choice when a larger drill diameter is needed but the available chuck capacity is limited to 1\/2 inch. Typical users include machinists, pipefitters, HVAC fabricators, and maintenance technicians working in shop or field environments where heavy-gauge metal drilling is routine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e43\/64 inch cutting diameter (0.6719 inch decimal) with a 1\/2 inch reduced shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003e118-degree split point enables fast starts and reduces walking on hard metal surfaces\u003c\/li\u003e\n\u003cli\u003eCobalt construction resists heat buildup during extended or high-speed drilling in ferrous metals\u003c\/li\u003e\n\u003cli\u003e3 inch flute length supports drilling depths up to 3 inches\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to chip or peel during high-stress cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ferrous metals as the primary workpiece material, with secondary compatibility for aluminum, copper, magnesium, nickel, cermet, synthetic, and titanium materials.

Secure the reduced shank firmly in a 1\/2 inch chuck before use and verify the bit is fully seated to prevent slippage under load. Use appropriate cutting fluid for the target material when recommended by shop procedure, even though this bit does not have an internal coolant channel. Inspect the cutting edges for wear or chipping before each use and replace if the split point shows damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 43\/64 inch (0.6719 inch decimal)\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: 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: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eCoolant\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\u003eSeries\u003c\/strong\u003e: R56CO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 6000424\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695732097330,"sku":"6000424","price":85.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f81fd928e748a33de5440444b6697c3.jpg?v=1788337850","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000424-cobalt-drill-bit-43-64","provider":"Voomi Supply","version":"1.0","type":"link"}
