Precision Twist Drill 6002278 Combo Drill Countersink

Product Description

The PRECISION TWIST DRILL 6002278 is a combination drill countersink designed for precision drilling and countersinking in a single operation. Built from solid carbide with a bright, uncoated finish, this tool delivers consistent performance in metalworking and fabrication applications. It features a 3/16-inch body diameter, a 5/64-inch drill point diameter, and a 60-degree included angle. The neutral cutting direction suits both right-hand and left-hand machine setups. At 2 inches overall length, this compact tool fits standard drill and milling machine chucks used by machinists and tooling professionals.

This combo drill countersink is suited for light-duty countersinking and spot-drilling tasks in machine shops, maintenance facilities, and production environments. The double-end configuration extends tool life by providing two usable cutting ends. Series DC construction follows a plain cutting edge style with no taper and no insertable cutter head, making it a straightforward replacement or stock tool for general countersinking work on metal substrates.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Secure the tool in an appropriate collet or drill chuck rated for the body diameter before operation. Ensure the machine spindle is fully stopped and locked out before changing or inspecting tooling. Follow applicable shop safety standards and machine tool manufacturer guidelines when setting spindle speed and feed rate for carbide tooling.
