Suited for drilling in uncono-

 solidated formations such as

sandy loam and clay. Designed

 with a smaller diameter to

 minimize drag when pulling out

 of hole and minimizing material

sloughing.

 

 

Ideal for consolidated forma-

 tions, cemented gravel and

 concrete.  Hard surfacing

 increases cutterhead life

 in hard, abrasive formations.

 Designed to accept a

wooden plug or brass guide

for use with the overshot

wireline system.
