STANDARD CONSTRUCTION & HEX-COR^® AUGERS

Foremost Mobile Standard Construction and HEX-COR®

augers have been tested in the fieldand independently

tested in the laboratory and proven to be equal to or

stronger than any other auger in the industry.

All Foremost Mobile continuous flight augers are

manufactured through use of an automatic inert

gas metal arc welding process to assure

consistent high quality and maximum strength.

Flights are formed with a slightly tapered concave

surface designed to throw cuttings toward the

shaft, minimizing clogging and auger drag. Timed

flight pitch is set at an optimum angle to produce

the best conveyance of material for general auger

exploration work and to maintain continuity of the

flight spiral from one section to the next.

Uniform bead hardfacing, standard on HEX-COR®

augers and optional on Standard Construction,

ensures Foremost’s flight edges have sufficient

chrome-manganese alloy for non-brittle toughness

and greater resistance to abrasion.

Standard Construction augers are manufactured

by conventional methods with the exception of the

continuous flighting which is welded on both sides

to the center shaft by an exclusive manufacturing

process. The center shafts of Standard

Construction augers are formed of high quality,

low carbon steel tubing to provide minimum weight

with maximum strength and rigidity.

Innovative HEX-COR® augers have many

advantages over Standard Construction augers.

In addition to superior strength, they have no

shank/socket bulge to impede cutting conveyance

and come with full length, flight-edge hardfacing

standard. They are completely interchangeable

with other augers of common shank and socket

size, use all auger heads of matching shank

design, and are easily repaired in the field.

The flighting and the center shaft, made of the

highest quality steels, are welded into one unit

utilizing inert gas metal arc welding. The center

shaft tube of HEX-COR® auger is hex-pierced to

the hex shank size throughout its length so that

shanks simply slip into the center shaft. This

design allows fast replacement of worn or broken

shanks in the field.
