DPI is focused on manufacturing quality in-hole tools that will stand up to the rugged conditions encountered in Geo-Tech and Environmental drilling. The overburden and top of bedrock is the region of the earth's strata that represents the toughest conditions for drilling tools.

We utilize premium alloy steel, because it delivers a longer wear life and stands up to challenging in-hole conditions.

We further enhance the strength of the tool joint with heat treatment, raising both its tensile and yield strength. DPI applies its experience and expertise in Engineering, Metallurgy, Manufacturing Technology, and Workmanship to deliver a product you can trust.
