49910 Solid Center Auger Bit, 5/8-in., 7-1/2-in. Oal

The Irwin 49910 is a full-length heat-treated solid center auger bit designed for drilling holes in wood. The wide lands keep the bit straight as it bores through the hole, while 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.

This bit features a single spur cutting edge that scribes the circumference of the hole for a smoother finish. The coarse screw point provides fast boring in both hard and soft woods. The solid core design and full-length heat treatment strengthen the twist section where the greatest strain occurs, guarding against bending in heavy-duty applications.
