The success of the air-powered Alminco Bull Ant is in its simplicity of design and operation. It can be used on its own as a brace, but is specifically designed for use with the Alminco Cub Borer. These combined Alminco 'Legends' give a simple, lightweight solution for rib bolting and drilling of test or blast holes.

Manufactured using filament wound fibreglass and a stainless steel piston rod, the strong but lightweight Bull Ant can be swiftly and accurately repositioned using the push-button retraction valve. The snap action leg contraction allows the Bull Ant to walk forward as it works and a claw spike on the base increases grip and stability.
