Back Reamers for hardpan and rock

posted in: Uncategorized | 0

As an addition to the Prairie Dog Boring Equipment heavy duty 2″ pilot bit designed for use in hard pan, stabilized soil, cobble, sandstone, shale, limestone and other borable rock.  We are now building back reamers in 4″, 6″ and 8″ diameters for the same conditions.  The four blade conical design presents more carbide for tougher conditions.  It also stabilizes the back reamer along with the outer ring to significantly reduce vibration.  Carbide inserts inserts along the entire cutting edge and in the outer ring offer aggressive cutting performance and excellent wear resistance for long life. These bits are only recommended for the 900TW, 1200TW and 1800TW.  They are available in SMSD and LGSD threads.

These bits can be ordered from the e-commerce section of the webpage.  Simply select “shop” at the top of the page.
