Precision Twist Drill 6000869 Taper Shank Drill Bit 7/16

Product Description

The PRECISION TWIST DRILL 6000869 is a taper shank drill bit designed for high-performance metal drilling in industrial and trade applications. It measures 7/16 inch (0.4375 inches) in diameter and features a 2MT (Morse Taper 2) shank for secure, self-holding mounting in compatible spindles and tailstocks. The 135-degree notched point reduces walking on entry and requires less thrust than a 118-degree point. A gold oxide finish provides mild lubricity and corrosion resistance. This bit is manufactured from high speed steel and is suited for machinists, toolroom operators, and maintenance technicians working on drill presses, lathes, and milling machines.

This drill bit is built for use in production and maintenance environments where a Morse Taper 2 spindle is available. Typical applications include drilling through steel, cast iron, and similar ferrous materials in both shop and field settings. The spiral flute and web-thinned point design support efficient chip evacuation and reduced cutting forces. It follows ANSI standards and belongs to the Series 209CO line, which is oriented toward high-performance tooling for demanding metal-cutting work.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with Morse Taper tooling. Before mounting or removing the bit, power down and lock out the machine per OSHA lockout/tagout procedures. Seat the taper shank fully into the spindle socket and confirm it is secure before running the spindle. Use a drift key in the spindle slot to remove the bit — do not strike the bit directly.
