More carbide cutters than competitive fluted reamers mean that this versatile, compact tool makes tracks in lots of different soil types. Faster, smoother cutting action, longer life and more successful bores each day. Boom. Juggernauts with built-in swivels keep the reamer assembly as short as possible for reaming in cobble or loose rock. Juggernauts with pulling eyes save money by using one clevis swivel on multiple reamers.
