ROTO-BORE "Standard" Dry Compaction Bits

These high quality bits are for dry-boring in clay and other compressible soils. They are self-feeding and produce clean, compacted bore holes.

All ROTO-BORE Bits are machined from solid chrome-moly alloy steel bar stock on state-of-the-art CNC lathes and machining centers. All bits are quenched and tempered to an average tensile strength of 153,000 psi for optimum strength and toughness.
