Bits & Blades

Harder, Faster, Stronger Bolt-On Blades and Directional Drilling Bits

These nearly indestructible bits & blades are built to withstand all the tough spots and rough patches Mother Nature throws in your way. Most of our bits have unique features that allow you to utilize FastBack® attachments for quick pullbacks. Our computer designed, field tested, signature red directional drilling bits are a force to be reckoned with.


Drillers that have been struggling to find a directional blade for hard ground conditions now have a solution. The Melfred Borzall engineers, with their impressive history of successfully addressing real-life challenges in HDD, have developed a new directional blade that not only increases drilling efficiency, but also addresses everyday production-draining issues such as blade drag, carbide wear and pullback efficiency. The Red Diamond Blade design is tougher and smarter.
