Terex Redrill's Infinity series rotary blasthole drills have a main frame with steel tubing that is cross-braced and reinforced. The drills feature a three-point oscillating suspension system for rugged terrain without transferring excessive torsional force to the main frame. Rectangular steel tubing on all four chords and cross members of the mast combine to create a torsionally strong unit, the company says. All Infinity series rotary drills have dust-collection systems, which have no moving parts. The drills also offer a large main deck area, which provides access to maintenance components. Terex Redrill
