The bit features a 1-7\/8 inch cutting diameter with a 3\/4 inch straight-cylindrical shank, making it compatible with standard drill chucks without requiring a large-bore spindle. The 118-degree standard point angle provides a self-centering entry suited to common metalworking applications. At 6 inches overall length with a 3-inch flute length, this bit handles moderate-depth drilling tasks efficiently. It is manufactured from high speed steel with a bright, uncoated finish and is part of the Series R58 line.\u003c\/p\u003e\u003cp\u003eThis bit is intended for trade and industrial use where a large-diameter hole is required but the available machine spindle accepts only a 3\/4 inch shank. Typical applications include HVAC duct fabrication, mechanical rough-in, structural steel drilling, and general shop work. The right-hand spiral flute design clears chips effectively during through-hole drilling in ferrous metal, aluminum, copper, magnesium, nickel, titanium, and synthetic materials. The reduced shank configuration extends the range of machines that can run a 1-7\/8 inch bit without a Morse taper or large-capacity chuck.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-7\/8 inch cutting diameter with 3\/4 inch reduced straight-cylindrical shank\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for self-centering entry on flat and curved stock\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluid where required\u003c\/li\u003e\n\u003cli\u003eSeries R58 — meets ANSI standards for reduced shank drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose reduced shank drill bit compatible with drill presses, milling machines, and magnetic drills equipped with a 3\/4 inch or larger chuck capacity.

Secure the 3\/4 inch shank fully in the chuck before operation and verify chuck key is removed prior to powering the machine. Use appropriate cutting fluid for ferrous and hard non-ferrous materials to extend tool life and reduce heat buildup. Follow applicable shop safety codes and wear ANSI-rated eye protection during all drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1-7\/8 inches (1.8750 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\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\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\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\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Aluminum, Copper, Magnesium, Nickel, Synthetic, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: Not required (coolant compatible)\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.63 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: 6000131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699706757426,"sku":"6000131","price":432.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5650dd42757e4136b3f50dcd2d385654_bfdf3dc9-ffd8-4a7d-bb50-c838cb212407.jpg?v=1788379569","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000131-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
