CSS Drilling Tools offers a wide range of hole openers for oil and gas wells, storage wells and salt dome projects. We provide customers with a choice of fixed-arm body designs dressed with field changeable, sealed and non-sealed cutters. Lower body designs include circulation jets arranged in various patterns for effective and thorough hole cleaning action. Hole Openers can be furnished with integral bull noses as well as suitable box-down connections.

Hole Opener bodies are machined from 4141/45 heat-treated alloy bar. Cutters are machined (not cast), and then heat treated to proven specifications to ensure maximum cutter life. Quality Control consistently ensures effective, economical application of all tools in the demanding downhole conditions. Hole Openers, drag bits and stabilizers are also available in odd and unusual sizes.

Sizes are as Follows
*Oil and Gas Well Drilling Tools - 5-7/8" though 36"
*Storage well/Salt Dome Drilling Tools - 12-1/4" through 48"
*Special Projects - Larger sizes available upon request

The RHO Hole Opener design criteria has allowed cone pocket cross sections to be increased by approximately 20%. The tool has arms and cutters that can be changed to increase the size of the hole drilled using the same hole opener body. The cutter is carried on the body of the tool and retained by an interchangeable arm assembly. This system eliminates the customary pin arrangement that was used to support previous hole openers.
