With the ever increasing power of today's drilling rigs, a high quality, well built auger is a necessity. Jeffrey Machine augers are second to none when it comes to high quality and high strength. We have just added a new innovation to to our 30" and larger foundation rock augers that nearly doubles the strength of the flighting at the critical stress points. We call them laminates. We are always looking for ways to make augers better and stronger and we welcome your input.
