EXTReam reamers from Railhead Underground Products are available in five sizes from 6- to 16-inch diameters with connections for virtually every drill. Field-replaceable teeth allow the user to stay on the job, saving downtime. They come 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-, 8- and 10-inch units 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 using the reamer as a stabilizer for subsequent reamer passes. 817/594-6663; www.railhead.com
