Chicago-latrobe 49711 Taper Length Drill Bit 11/64 in Hss

Product Description

The CHICAGO-LATROBE 49711 is a taper length drill bit designed for general-purpose drilling in metal and ferrous materials. Built from high speed steel with a coated finish, this bit features an 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The spiral flute runs 3.375 inches in length along a straight shank measuring 0.1719 inches in diameter. At 5.75 inches overall length, the taper length body gives added reach compared to a jobber-length drill while maintaining rigidity. Right-hand cut geometry suits standard drill presses and handheld power drills.

The 49711 is suited for production and maintenance drilling in alloy steel, carbon steel, and cast iron. Its general-purpose grade makes it a practical stock bit for machine shops, fabrication facilities, and maintenance departments that drill a range of ferrous workpieces. The Series 120 designation places it within CHICAGO-LATROBE's standard taper length line, commonly used where a jobber drill lacks the reach to clear a fixture or workpiece edge.

Key Features

• High speed steel construction for durability in ferrous metal drilling
• Coated finish for improved wear resistance and lubricity
• 118-degree standard point angle for general-purpose entry geometry
• Web-thinned tapered web reduces axial thrust at the cutting tip
• Taper length body at 5.75 inches total for added reach beyond jobber length
• Right-hand cut, straight shank compatible with standard drill chucks

Compatibility

Designed for use in standard three-jaw drill chucks accepting a 0.1719-inch straight shank. Suitable for drilling alloy steel, carbon steel, and cast iron workpieces in general-purpose machining and maintenance applications.

Installation Notes

This bit is installed and operated by machinists, tool-and-die professionals, and maintenance technicians using drill presses, milling machines, or handheld power drills. Ensure the chuck is fully tightened and the workpiece is secured before beginning a cut. Use appropriate cutting fluid when drilling steel to extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
