Irwin 9/16 Auger Bit
Single cutting spur scribes the outside of the hole for faster drilling, cleaner holes, and a smoother finish. Solid-center design increases durability and provides rigidity for smooth, straight drilling. Coarse screw-point for fast drilling in soft and hard woods. Full-length heat-treating strengthens the twist, guarding against bending in tough applications, and improves overall bit durability and drilling life.
