The Irwin 49911 is a solid-center auger bit designed for boring through hardwoods and softwoods. This 11/16-inch diameter bit features a coarse screw point that drives forward, reducing the time and energy needed to create holes. The full-length heat-treated construction strengthens the twist where the greatest strain occurs, guarding against bending during heavy-duty drilling applications.
Solid-center auger bits deliver rigidity for boring applications. The wide lands keep the bit straight as it bores through the hole, while the single spur cutting edge scribes the circumference for a smoother finish that requires less cleanup.
Features and Benefits
- Wide Lands: Keep the bit straight as it bores through the hole.
- Chip Evacuation: Flutes are ground behind the lands to funnel chips to the inside of the bit and away from the outside diameter, producing faster, cleaner cuts.
- Single Spur Cutting Edge: Scribes the circumference of the hole for a smooth finish and reduces post-drilling cleanup time.
- Coarse Screw Point: Provides fast boring in hard and soft woods with minimal effort.
- Full-Length Heat Treatment: Strengthens the entire bit and reinforces the twist where the greatest strain occurs, guarding against bending in heavy-duty applications.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work.To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
