The industry’s closest at-bit reamer 

The TDReam tool is an innovative reaming-while-drilling downhole design that allows operators to enlarge the whole section in a single run. Due to the conventional hole enlargement tools position in the BHA, rathole enlargements require additional trips.  Now, with the TDReam, it can be done at once, saving time and money.
