Ship Auger Bit 38440
The Century Drill & Tool 38440 is a 4 inch ship auger bit built for boring holes in all wood types including treated lumber and poles. Its single cutter and spur design with a solid center twist reduces vibration during operation. The short length suits electricians and plumbers working in tight, confined spaces. This accessory fits standard power drills for heavy-duty wood drilling tasks.
Upgrade From Standard Spade Bits
This bit replaces flat spade bits when cleaner entry holes and less tear-out are required in dense or treated timber. The solid center twist pulls the bit through the workpiece with less wobble than a spade bit allows. The jump is worth it for repetitive pole or timber framing where hole accuracy and reduced vibration lower operator fatigue. It is not for buyers who need larger diameter capacity or extended reach beyond four inches.
Easy Chuck Installation
The bit installs by tightening the drill chuck onto its shank; no special adapters or pilot holes are needed. What usually goes wrong is using excessive speed which can overheat the cutter when boring treated wood. Clearing chips frequently prevents binding in deep holes. Ensure the chuck is fully secured to avoid slippage under the high torque this design generates.

Questions about this item
What shank size does the 38440 ship auger bit need for a secure fit?
The bit uses a standard hex shank that fits 1/2 inch and larger drill chucks; tighten the chuck fully on the flats to prevent slip.
How do you start the 4 inch ship auger bit without it walking across the wood?
Apply light pressure, let the spur pull the bit in, then increase speed; forcing it before the spur engages is the common mistake.
When should the 38440 auger bit be sharpened or replaced?
Sharpen the single cutter and spur when feed slows or smoke appears; replace if the twist cracks or the shank rounds off.
