down hole hammers and bits


Numa has led the industry in innovative design of reverse circulation hammers and bits. These RC products have the unique ability to bring all cuttings up the center of the hammer and drill string to be safely collected at the surface, which is essential in today's environmentally conscious society.

Recently, we have engineered a new, breakthrough RC bit design that drastically improves hole cleaning and overall drilling speed. By deepening the channel ways and side exhausting, the new design is able to efficiently flush more air over the bit face resulting in a greater recovery and accurate down hole sample at the surface - all at a much faster drilling rate.

Currently, our RC hammer and bit line has the capability to drill holes from 4-3/4" to 36" (121 - 914 mm) in diameter, with more designs in the works. As with our conventional line, all RC products provide incredible performance and reliability in tough drilling applications around the world.
