Back Reamers for hardpan and rock

posted in: Uncategorized | 0


Now, in addition to their heavy-duty 2″ pilot bit, Prairie Dog has introduced back reamers in 4″, 6″, and 8″ diameters. These back reamers are designed for use in hard pan, stabilized soil, cobble, sandstone, shale, limestone, and other borable rock conditions.


The four-blade conical design provides more carbide for tougher conditions and helps stabilize the back reamer, reducing vibration significantly. With carbide inserts along the cutting edge and outer ring, these bits offer aggressive cutting performance and excellent wear resistance for a long lifespan.


Please note that these bits are recommended for use with the 900TW, 1200TW, and 1800TW models of Prairie Dog Boring Equipment. They are available in SMSD and LGSD threads.
