Reaming Bits & Hole Openers

Reaming bits and hole openers enlarge a borehole. Compare the illustrated assemblies by their pilot or guiding section, enlarged cutting zone and connection. These product families include integral, guided and modular layouts; the series numbers do not describe a universal adjustment range.

• Integral heads: compare 69/100 and 113/250 series.
• Guided and combination designs: review 75-to-94 guided, 94/140 combination and pointed-guide configurations.
• Modular hole opening: compare the 200/500 drag assembly. The reaming core bit is a separate option when a core passage is also required.

For a quotation, send the existing or pilot-hole diameter, required finished diameter, hole depth and direction, formation, rig torque information, flushing method and connection drawing. Discuss an OEM configuration or compare the products below.
