The Irwin 49912 Solid Center Auger Bit is a full-length heat-treated drill bit designed for boring in both hard and soft woods. The solid center construction with wide lands keeps the bit straight as it bores through the hole. The flutes are ground behind the lands to funnel chips to the inside of the bit and away from the outside diameter, producing a faster, cleaner cut.
A single spur cutting edge scribes the circumference of the hole for a smoother finish. The coarse screw point provides fast boring in hard and soft woods. Full-length heat treatment strengthens the twist where the greatest strain occurs, guarding against bending in heavy-duty applications and delivering reliable performance for woodworking and general boring tasks.
Features and Benefits
- Wide Lands: Keep the bit straight as it bores through the hole.
- Optimized Flute Design: 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 smoother finish.
- Coarse Screw Point: Provides fast boring in hard and soft woods.
- Heat-Treated Steel Construction: Full-length heat treatment strengthens the twist where the greatest strain occurs and guards against bending in heavy-duty applications.
- Deep Hole Capability: The 4-1/2 inch twist length provides ample reach for deep drilling tasks, while the 7-1/2 inch overall length suits standard drilling operations.

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.
