Built from cobalt high-speed steel, this bit delivers superior heat and wear resistance compared to standard HSS tooling. The 27\/32 inch cutting diameter pairs with a 1\/2 inch straight-cylindrical shank, allowing use in standard 1\/2 inch chucks while accessing larger bore sizes. The 118-degree split point promotes fast starting and reduces walking without a center punch. Overall length is 6 inches with a 3-inch flute length, giving a maximum drilling depth of 3 inches. The bright, uncoated finish suits shops that re-sharpen their tooling regularly.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for machinists, pipefitters, ironworkers, and maintenance technicians who need to bore oversized holes through ferrous metals, aluminum, copper, nickel alloys, titanium, and magnesium. The reduced shank design extends usability to standard 1\/2 inch drill chucks and magnetic drill presses without sacrificing cutting diameter. The Series R56CO designation places it in PRECISION TWIST DRILL's cobalt reduced-shank line, built to ANSI standards. Typical applications include structural steel fabrication, pipe fitting, equipment maintenance, and HVAC sheet-metal work requiring holes larger than 3\/4 inch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for high heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e118-degree split point for fast, self-starting cuts with reduced feed pressure\u003c\/li\u003e\n  \u003cli\u003e27\/32 inch cutting diameter with 1\/2 inch reduced shank fits standard chucks and magnetic drills\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 efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with re-sharpening and standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant geometry for consistent, repeatable performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 1\/2 inch keyed or keyless drill chucks and magnetic drill press units.

Secure the workpiece firmly before drilling and ensure the shank is fully seated and tightened in the chuck before applying power. Apply an appropriate cutting fluid when drilling ferrous metals or hard alloys to extend tool life and maintain bit geometry. Do not exceed the rated drilling depth of 3 inches and back out frequently to clear chips when drilling deep holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 27\/32 inch (0.8438 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular Helix)\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: Cobalt 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, Copper, Magnesium, Nickel, Titanium, Synthetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No (recommended for extended tool life)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R56CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: 6000386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699693879602,"sku":"6000386","price":107.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9f634bab3e52fffe5b689e5fa4248a6.jpg?v=1788379312","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000386-cobalt-drill-bit-27-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
