Precision Twist Drill 6000873 Taper Shank Drill Bit 3MT

Product Description

The PRECISION TWIST DRILL 6000873 is a taper shank drill bit designed for drilling precise, large-diameter holes in metal and similar hard materials. It features a 13/16-inch (0.8125 inches) diameter, a 3MT (Morse Taper 3) shank for secure chuck engagement in compatible drill presses and lathes, and a 135-degree notched point with web thinning for fast starts and reduced thrust. The high speed steel construction carries a gold oxide finish that provides light lubricity and corrosion resistance. Overall length is 10.75 inches with a spiral flute length of 6.125 inches. This bit is built to the ANSI standard for consistent dimensional accuracy.

This bit is suited for production and maintenance machining environments where a 3MT taper shank spindle is available. Typical applications include drilling through steel, cast iron, and similar structural metals on drill presses, milling machines, and lathes equipped with a Morse Taper 3 socket. The right-hand, regular-spiral flute geometry efficiently evacuates chips during through-hole and blind-hole operations. It is part of the Series 209CO lineup and carries a high performance tool rating for demanding cutting conditions.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully de-energized and locked out before seating or removing the taper shank. Clean both the taper shank and the spindle socket thoroughly before insertion to ensure full contact and prevent slippage. Use a proper drift key and drift slot to safely eject the bit from the spindle when changing tools.
