Features

Exclusive Cat® Mounting Bracket

Exclusive Cat mounting bracket is common to all Cat Auger designs. Incorporates a full-width torque tube, an articulated joint, cradle, and stand. These features provide superior structural reinforcement, positioning flexibility, easy transportation, near-vertical storage, and easy work tool engagement.

Articulated Joint

Articulated joint ensures auger hangs straight, independent of machine positioning.

Mechanical Swing Stops

Mechanical swing stops protect from auger over swing.

Rugged Bits for Every Application

Rugged bits are adaptable to a number of projects. Standard bits, tree bits, industrial bits and standard rock drill head bits (bolt-on) are offered to cover a wide variety of applications and ground conditions.

Bit Extensions and Adapters

Various extensions allow for digging deeper and adapting to round or hex shaft bit designs. Retention pin reduces time to auger flight changes.
