foundation augers: bullet auger

Jeffrey Machine's 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 APPLICATION: Jeffrey Machine 'Bullet Tooth' rock 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.

Recommended rotation speed 20 to 35 rpm, with constant to maximum down pressure (applied). Click on the 3D auger and when the window opens and the auger appears, point your mouse at the auger and left click and drag to spin it around a time or two and just imagine what that does to hard rock formations. You can depend on the appropriate Jeffrey Machine auger to do the job no matter what obstacles you are faced with.
