Deck Bushing

Matrix Rotary Deck Bushings are engineered to withstand the tough conditions common to Blast Hole Drilling. They provide lateral support to the drill string at the rig deck assisting the smooth rotation of the Drill Steel. Our range of deck bushing includes sizes to accommodate Drill Steel to diameters up to 8 inches.

Subs and Accessories

Subs

Blast Hole Subs, manufactured by Matrix, are machined from 4140 alloy steel bar stock that has been heat treated to maximize strength and durability. Subs need to be tough to hold up under the unrelenting stresses of blast hole drilling. Using the best USA produced alloy steel is a good starting point. Threads and flats are cut on CNC machining centers by our experienced operators, and our strict quality control assures consistent field performance.

We offer our subs in all blast hole tooling diameters, lengths, and breakout flats. Machined to customer specification API Reg. – IF – FH – BECO
