Ship Auger Extension 12in

The Century Drill And Tool 38113 extends the reach of ship auger bits by twelve inches. It is designed for professionals who need to bore deeper holes in timber without changing to a longer bit. The half-inch hex shank fits standard drill chucks and quick-change adapters. This accessory suits contractors and woodworkers working on thick structural members.

Thermals noise and power draw

The extension has no motor, electronics or moving parts of its own, so it generates no heat and draws no power. Operational noise is limited to the drill and bit combination already in use. It adds only a small amount of rotating mass to the drive train. There are no thermal limits or duty-cycle restrictions to observe.

Bundled accessories and software

The package includes the extension body and set screws for locking the auger bit in place. Correct installation requires aligning the set screws with the flat on the auger shank before tightening. No software, drivers or calibration tools are supplied or required. The only consumable is the set-screw hardware if it becomes damaged.

Questions about this item

How do I install the 38113 extension onto a ship auger bit without it slipping?

Align the two set screws so they sit parallel to the flat on the auger shank, then tighten each screw firmly; skipping this alignment is the step that causes the connection to fail.

What part of the 38113 extension will wear first and need replacement?

The set screws and their threads take the full torque load, so they will strip or loosen before the 12 in. steel body shows any wear.

What is the practical length limit when stacking multiple 38113 extensions for deep holes?

Each 12 in. section adds leverage and flex, so run-out and vibration become noticeable after two or three coupled together, limiting usable depth.
