The IRWIN 16mm Speedbor Max auger bit is built for fast, clean wood boring, with a tri-flute design that ejects chips quickly to keep drilling moving. The full-length heat-treated steel body adds strength for repeated use on the job.
A full screw tip pulls the bit through the timber for easy self-feeding, while the tri-flute geometry reduces binding for smoother drilling. It is a practical choice for general carpentry, framing and timber boring tasks where speed and clean holes matter.
