Underreamer drilling tool

It will accommodate a standard rock bit to drill and underream simultaneously, and with a jet sub on bottom. This allows for good hole cleaning and bottom hole stabilization, as well as being able to wash the cutter arms.

Tubing Underreamer. The tubing underreamer - clean out tool and cutter is a uniquely designed tool which will operate underneath production packers without removing or pulling the packer.

Scale, cement, corrosion, or formation debris that may have formed beneath the packer can easily be removed. By dislodging this unwanted foreign material from the well bore beneath the production packer, production of the well will increase without removing the packer from the well bore.

The tool can also be dressed with tungsten carbide to cut tubing. Milled tooth, tungsten carbide insert TCI , or polycrystalline diamond compact PDC cutters can be used according to the application. Premium content requires special account permissions.

The casing drive acts similar to a down hole hammer. When the hole is first started, the casing driver sits inactive on the casing acting as a water diverter. The more the anvil is closed, the harder the casing driver hits. The CD turns on and off automatically and runs only when the casing lags behind the underreamer, causing the anvil to close. Maximize your underreaming with a Holte URE designed to have a wider cutting edge where you need it most.

The Holte oval shape places more cutting edge on the bore hole wall.
