Chicago-latrobe 49713 Taper Length Drill Bit 13/64 in

Product Description

The CHICAGO-LATROBE 49713 is a taper length, high speed steel (HSS) drill bit designed for general-purpose drilling in metalworking applications. It measures 13/64 inch (0.2031 inches) in diameter with a 118-degree standard point angle and a spiral flute configuration. The straight shank and right-hand cut make it compatible with standard drill chucks. At 6 inches overall length (OAL), the taper length body provides added reach compared to a jobber-length bit without sacrificing rigidity. A web-thinned, tapered web design reduces thrust requirements at entry and improves chip evacuation. This bit is used by machinists, maintenance technicians, and trade professionals working with ferrous and cast metals.

The 49713 is suited for drilling alloy steel, carbon steel, and cast iron in both production and maintenance environments. The 6-inch OAL and 3-5/8-inch flute length make it well-suited for applications where a standard jobber bit lacks the reach needed to clear fixturing or access deeper hole locations. The coated finish provides moderate wear resistance for general-purpose use. Series 120 designates it as part of CHICAGO-LATROBE's standard taper length line.

Installation Notes

Installation and use should be performed by machinists or qualified trade personnel familiar with drilling equipment and metal cutting practices. Secure the workpiece and verify chuck tightness before operation. Ensure the drill press or handheld drill is powered down and de-energized before inserting or removing the bit. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and maintain dimensional accuracy.
