1-1/2" SHIP AUGER.
KW's: power ship auger bit drill.
Single-spur cutting edge scribes the circumference of the hole for a smoother finish.
Fast boring in hard and soft woods. Bits have a 4-1/2" twist length and a 7-1/2" overall length.
Full-length heat treatment guards against bending and strengthens the twist.
