Bore holes in wood with the Irwin drill bit. Made of high-carbon steel, this drill bit is durable, strong and safe to use. The auger drill bit produces a smooth and uniform hole. With a shank drill bit, the bit will fit into the drill's chuck firmly. Use the wood-boring bit with a power tool to drill wood and metal.

Wide lands keep the bit straight as it bores through the holeFlutes are ground behind the lands to funnel chips to the inside of the bit and away from the outside diameter, producing a faster, cleaner cutFull-length heat-treated bit guards against bending in heavy-duty applications, and strengthens the twist where the greatest strain occursSolid center design provides extra rigidity while drivingCoarse screw point provides fast drilling in hard and soft woodsSingle-spur cutting edge scribes the circumference of the hole for a smoother finish
