Century Drill & Tool 38456 4 inch ship auger bit

4" Ship Auger Bit – Confined-Space Wood Drilling

The Century Drill & Tool 38456 is a 4" ship auger bit built for boring holes in all wood types, including treated lumber and poles. Its single cutter and spur with a solid centre twist cuts cleanly while keeping vibration low. The short length lets you work in tight, confined areas where longer bits cannot reach. It suits electricians, plumbers and timber framers who need precise holes in restricted spots.

Check Chuck Capacity and Wood Type Before Buying

Verify that your drill chuck accepts the bit shank diameter and that the tool delivers enough torque for dense or treated timber. The 4" overall length limits maximum hole depth, so confirm it meets your required drilling depth. Ensure the workpiece is clamped securely, as the aggressive spur can pull the bit forward quickly in soft or green wood.

Replaces Longer Auger Bits When Access Is Restricted

This bit replaces standard-length ship augers in situations where joists, studs or cabinetry block a longer tool. The jump is worth it when you regularly drill between floor joists, inside cabinets or around pipework where every centimetre of clearance matters. It is not for deep through-bolting in thick beams or for production drilling where a longer bit would save repositioning time.
