Profile: Jeffrey Machine, Inc. is a full line machine shop offering general machine work, tool and die work, fabricated steel, and all types of hard surface welding. We also do repairing, rebuilding and manufacturing of augers for skid steers, utility trucks, heavy construction equipment and light construction equipment. We offer foundation auger, medium duty auger, and light duty augers. Our Bullet Augers are designed to maximise drilling. They are best suited for solid and fracturable rock as well as compacted soils. All augers are made with heavy duty lead flighting. These bullet augers are best suited for medium to hard rock drilling in fractured rock strata as well as solid non-fractured rock and soils with boulders of cobble rock material.
