The EXTReam reamers are now available in five sizes from 6 inches to 16 inches in diameter with connections for virtually every drill. The field replaceable teeth allow the user to stay on the job saving down time. The EXTReam reamer comes with a complete set of jets and plugs so the reamer may be configured to the varying ground conditions encountered throughout a project. The newly designed 6 inch, 8 inch and 10 inch EXTReam Reamers are built with an API pin and box with a removable pulling eye at the back of the reamer. This allows the user to quickly hook up many configurations including pulling reamers in tandem or use the EXTReam reamer as a stabilizer for subsequent reamer passes. 888.313.7455,
