It carries a 1-9\/16 inch cutting diameter on a 3\/4 inch straight-cylindrical reduced shank, allowing it to fit standard 3\/4 inch drill chucks without requiring a larger capacity machine. The bit is manufactured from high speed steel with a bright uncoated finish and ground to a 118-degree standard point angle. With a 3 inch flute length and 6 inch overall length, it suits general-purpose production and maintenance drilling in shop and field environments. Installation is performed by machinists, tool-and-die tradespeople, pipefitters, and HVAC fabricators.\u003c\/p\u003e\n\u003cp\u003eThis bit belongs to the PRECISION TWIST DRILL Series R58 and is intended for general-purpose drilling in ferrous metal as its primary workpiece material. Secondary compatible materials include aluminum, copper, magnesium, nickel, synthetic composites, and titanium. The right-hand cut and regular spiral flute geometry suit conventional drill press and hand-held drilling operations. The reduced shank design makes this large-diameter bit accessible on machines with 3\/4 inch chuck capacity, expanding its usefulness across a wide range of shop equipment without a dedicated large-chuck spindle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-9\/16 inch cutting diameter with reduced 3\/4 inch shank for broad chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry and centering\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish; no additional coating to interfere with regrinding\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eANSI-standard dimensions; Series R58 for consistent replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4 inch drill chucks on drill presses, magnetic drills, and similar equipment.

Power down and de-energize or lock out the drilling machine before changing bits. Use appropriate cutting fluid or coolant for extended runs in hard ferrous materials, even though the bit is rated for dry use. Worn bits should be reground or replaced rather than run at reduced cutting diameter to avoid workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-9\/16 inches (1.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical Reduced Shank\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, 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\u003eWeight\u003c\/strong\u003e: 1.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R58\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: 6000138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51720304263474,"sku":"6000138","price":318.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fef787fe087737ae32b710bf570e609.jpg?v=1788562349","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000138-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
