Precision Twist Drill 6001059 Taper Shank Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6001059 is a taper shank drill bit designed for drilling precise, clean holes in metal and general-purpose materials. Built from high speed steel (HSS) with an oxide finish, this bit handles the heat and wear demands of production and maintenance drilling. It carries a 3MT (Morse Taper 3) shank for secure seating in compatible drill press spindles and tailstocks. The 118-degree standard point angle with web thinning reduces entry force and improves centering. At 10.75 inches overall length with a 6.125-inch spiral flute, it provides the reach and chip evacuation needed for deeper hole work. Machinists, tool and die shops, and maintenance technicians are the primary installers of this bit.

This drill bit is suited for general-purpose drilling in ferrous and non-ferrous metals, plastics, and similar materials on drill presses, lathes, and milling machines equipped with a Morse Taper 3 socket. The right-hand cutting direction and regular spiral flute geometry make it a standard choice for production environments and job shop floor use. The Series 209 designation identifies it within the PRECISION TWIST DRILL product line, and it conforms to ANSI standards for taper shank drill geometry and tolerances.

Key Features

• 0.875 inch (7/8 inch) diameter with 0.8750 decimal inch precision
• 3MT Morse Taper shank for positive drive and easy removal with a drift key
• 118-degree standard point angle with web thinning for reduced thrust and accurate starting
• High speed steel construction with oxide finish for heat and wear resistance

• Right-hand cut, regular spiral — conforms to ANSI taper shank drill standards

Compatibility

Designed for use in drill press spindles, lathe tailstocks, and milling machine quills fitted with a Morse Taper 3 socket. No additional adapter is required when the machine socket matches 3MT.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with taper shank tooling. Power down and lock out the machine before seating or removing the bit. Insert the taper shank fully into the 3MT socket, aligning the tang, and seat firmly with a soft mallet if needed. Use a proper drift and drift slot to remove the bit — never strike the bit or chuck body to dislodge it.
