Precision Twist Drill 6000789 Taper Shank Drill Bit 2MT

Product Description

The PRECISION TWIST DRILL 6000789 is a taper shank drill bit designed for high-performance metal drilling in industrial and trade applications. Built from high speed steel with a gold oxide finish, this bit measures 27/64 inch (0.4219 inches) in diameter and features a 135-degree notched point for fast penetration and reduced walking on entry. The 2MT (Morse Taper 2) shank seats securely in compatible drill press spindles and machine tool holders. A web-thinned construction reduces thrust load, and the right-hand spiral flute evacuates chips efficiently. Licensed machinists, tool and die shops, and maintenance mechanics are the primary installers of this type of tooling.

This drill bit is suited for use in drill presses, lathes, and milling machines equipped with a No. 2 Morse Taper spindle or sleeve. It is appropriate for drilling steel, cast iron, and other ferrous materials in both production and maintenance environments. The 135-degree split point starts on contact without a center punch on flat stock, making it practical for job-shop and production-floor use. Conformance to ANSI standards ensures dimensional consistency for direct replacement in existing setups.

Key Features

• Series 209CO high-performance designation; meets ANSI dimensional standards

Compatibility

Designed for use in any drill press, lathe tailstock, or machining center equipped with a No. 2 Morse Taper (2MT) spindle or adaptor sleeve.

Installation Notes

Installation is performed by machinists or trained maintenance mechanics. Power down and lock out the machine before inserting or ejecting the taper shank. Seat the taper fully by hand and verify it is clean and free of chips before applying drive force. Use a proper drift and dead-blow mallet for ejection to avoid damaging the spindle bore.
