Built from high speed steel with a coated finish, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces cutting resistance at the tip. The straight shank measures 3\/4 inch in diameter, and the overall length is 9.75 inches. The right-hand spiral flute with a flute length of 5.875 inches provides efficient chip evacuation during general purpose drilling operations. This bit is part of the CHICAGO-LATROBE Series 120 line and is suited for use in drill presses, lathes, and hand-held drilling equipment by machinists, pipefitters, and industrial maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis taper length drill bit is intended for general purpose metal drilling in industrial and commercial maintenance settings. The 3\/4 inch diameter makes it a common choice for bolt clearance holes, conduit knockouts in heavy enclosures, and structural fabrication work where a standard jobber-length bit lacks sufficient reach. Material applications include alloy steel, carbon steel, and cast iron. The taper length body provides extra reach compared to a jobber-length bit without sacrificing rigidity. Diameter tolerance is held to +0.0000 to -0.0012 inches, making it suitable for applications requiring consistent hole sizing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction for durability in steel and cast iron drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general purpose metal drilling\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust and improves chip flow at the tip\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute, 5.875 inches long, for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight 3\/4 inch shank compatible with standard drill chucks and holders\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general purpose taper length drill bit for use in standard drill presses, milling machines, and hand drilling equipment that accept a 3\/4 inch straight shank.

Secure the straight shank fully in a properly rated chuck before operation and verify the chuck rating supports the 3\/4 inch shank diameter. Power down and de-energize all equipment before changing tooling. Use appropriate cutting fluid or coolant for the material being drilled to extend tool life, noting that this bit does not have a coolant-through design.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3.875 inches\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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.912 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: CHICAGO-LATROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49748\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51732791755058,"sku":"49748","price":91.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/736fcece2c3be70d7809a8ceb572f7de.jpg?v=1788746858","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-49748-3-4-inch-taper-length-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
