Blast Hole 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
