IRWIN 49905 AUGR BIT I-100 5/16″ X 7-1/2″

The IRWIN Industrial Tools I-100 5/16″ Auger Bit is expertly crafted for precision and performance in both hard and soft woods. Its single-spur cutting edge ensures a smoother finish by accurately scribing the circumference of the hole, while the solid center design enhances rigidity during boring operations. Built for durability, this auger bit features a full-length heat treatment that prevents bending and strengthens the twist at the points of maximum strain, making it ideal for heavy-duty applications. Additionally, wide lands help maintain straightness as the bit works through materials, while the meticulously designed flutes efficiently funnel chips away, contributing to faster and cleaner cutting results.
