When it comes to reamers, we’ve got your back. Whether you’re going through clay, sand or rock, Melfred’s wide assortment of backreamers is designed to get you through even the toughest conditions. Available in a number of different configurations and sizes, Melfred Borzall reamers help you get better production on backream and pullback from your Ditch Witch or Vermeer drill.
ABOUT Reamers
It doesn’t matter how good your Vermeer or Ditch Witch drills are if you don’t have the right reamer for your job.

Juggernaut Reamer
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. Performance Features:
Deluxe fluted backreamers
More cutters than any other reamer in its class create smoother cutting action
Deep, spiraled flutes allow for plenty of slurry to flow past the reamer
Compact, pocket swivels available in a range of capacities for all size Juggernauts
Pulling eye adapters available for all sizes
Available cutting sizes:
4.5″ – 16″
