Precision Twist Drill 6001179 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001179 is a taper shank drill bit engineered for drilling precise holes in metal and other hard materials. It features a 0.6496-inch (16.50 mm) diameter, a Morse Taper 2 (2MT) shank for secure seating in compatible spindles and tailstocks, and a 118-degree standard point angle with web thinning for improved centering and reduced thrust. The body is manufactured from high speed steel (HSS) with an oxide finish that provides modest lubricity and corrosion resistance. Overall length is 8.7813 inches with a spiral flute length of 4.9063 inches. This bit is a general-purpose tool intended for right-hand cutting in drill presses, lathes, and milling machines. Installation and use are performed by machinists, toolroom technicians, and skilled trade professionals.

This drill bit is suited for general-purpose metal drilling operations in production and maintenance environments. The 2MT taper shank mates directly to machine spindles, drill press quills, and lathe tailstocks with Morse Taper 2 sockets, eliminating the need for a separate chuck. The regular spiral flute geometry promotes efficient chip evacuation during through-hole and blind-hole drilling in steel, cast iron, aluminum, and similar materials. It is a solid choice for job shop, fabrication, and MRO applications where a reliable, standard-geometry HSS taper shank bit is required.

Installation Notes

Installation is performed by machinists or qualified tool operators. Before mounting or removing the bit, ensure the machine is fully powered down and the spindle has come to a complete stop. Insert the 2MT taper shank fully into the matching spindle socket and seat it firmly with a drift key if required; never force the taper with excessive impact. Inspect the taper surfaces for nicks, burrs, or debris before seating to ensure full contact and safe operation.
