7.2 Auger Selection Based on Drilling Application
The digger must be equipped with the proper auger type for the drilling application at hand. A wide range of
augers and sizes are available for drilling in compacted soils, frozen ground, and loose and solid rock. In some
applications the digger can be used to drill concentrate (without rebar) if adequate down pressure can be
applied to the auger by the power unit (not recommended for skid steer operated units).
PUFF Auger:
Designed to drill 2” diameter holes in solid rock or concrete for T-posts. Also referred to as the T-
post Puff Auger.
SDA Augers:
Designed for digging in soil only. Available in sizes from 6” to 36” diameter, and tree augers from
18” to 36” diameter sizes.
RAD Augers:
Designed for digging in soil, clay, loose and solid rock and concrete. Available in sizes from 9” to
36” diameter.
SRA Augers:
Designed for drilling in solid rock or concrete without rebar, fractured rock, frozen ground and
compacted soil. Augers are available in sizes from 4.5” to 6” diameter.
