The bit measures 53\/64 inch (0.8281 inch decimal) in diameter with a 1\/2 inch straight-cylindrical shank, allowing it to fit standard 1\/2 inch chucks even though the cutting diameter is larger. The 118-degree split point reduces walking at the start of the cut and lowers thrust requirements. At 6 inches overall length with a 3 inch flute length, it handles moderate-depth holes while maintaining rigidity. Cobalt construction provides elevated heat resistance compared to standard high-speed steel, making it well suited for hard or abrasive workpieces.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for industrial and trade applications where ferrous metal, stainless, titanium, and nickel-based alloys are regularly encountered. The reduced shank design is the key practical feature here: the 1\/2 inch shank lets machinists, fabricators, and maintenance technicians run a large-diameter bit in a standard 1\/2 inch drill press or hand drill chuck without requiring a larger collet or chuck upgrade. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling in shop, field, and maintenance-repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e53\/64 inch (0.8281 inch) cutting diameter with a 1\/2 inch reduced straight-cylindrical shank for use in standard 1\/2 inch chucks\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides superior heat and wear resistance over standard high-speed steel in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003e118-degree split point reduces bit walking and lowers drilling thrust on entry\u003c\/li\u003e\n  \u003cli\u003e3 inch flute length supports drilling to a maximum depth of 3 inches\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows easy visual inspection of wear and maintains sharp cutting edges\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with regular helix angle for reliable chip evacuation in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; Series R56CO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ferrous metals as primary workpiece material; also rated for aluminum, cermet, copper, magnesium, nickel, synthetic, and titanium workpieces.

Secure the 1\/2 inch shank firmly in a properly sized chuck before operation and confirm the workpiece is clamped or fixtured to prevent rotation. No coolant-through capability is present on this bit; use appropriate cutting fluid applied externally when drilling hard or heat-sensitive alloys to extend tool life. Inspect the cutting edges and split point before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 53\/64 inch (0.8281 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch decimal)\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, Regular Helix\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\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\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: 6000448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693393609010,"sku":"6000448","price":122.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a725336ca5c2456a48df9bc0b233f3c3.jpg?v=1788311699","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000448-cobalt-drill-bit-53-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
