Broken Taps Removed Using Armor Drill Tool

It is recommended that both the Armor Drill and Armor Mill tools be used in rigid machines (machining centers, knee mills, lathes) with the parts held securely. Using the hand wheel at the lowest speed, feed very slowly and keep a steady feedrate. Peck or stop frequently to remove chips from the hole. If the part needs to be drilled with a hand drill, operate the drill at faster rpms, use a strong, steady force, and keep the drill as straight as possible. It is important to prevent the tools from walking or deflecting, especially when first contacting the uneven part surface.

As with all machining, it is necessary to take appropriate safety precautions.
