Fastback System

Fastback System

Exclusive to Melfred Borzall the FASTBACK system is designed to get in and out of jobs quickly. Our system allows the customer to ream up to 12” without removing the bit. Ideal in tight areas where installing a reamer would be difficult and time consuming.


We believe in the term “you get what you pay for” when it comes to reamers. They stand up to the toughest conditions and outshine the competition on wear resistance. No matter the soil type we have the reamers to get you back and on to the next job.


Bolt and Thread-on Bits

No matter the soil type, we have the bit to tackle the job. Built to withstand the hardest conditions, these bits are manufactured to give our customers improved quality and wear resistance. Ask about our Red Diamond Bit or our Patent-pending Pit Bull bits, which increase productivity and reduce your chances of down-hole shear-off. Rock or Cobble? Not an issue with our thread on Iron Fist and Eagle Claw bits. Solid Rock? We offer Mud Motor options and Tri-cone bits. Ask about our Rent-it, Rock-it, Return-it, rental program. Melfred Borzall doesn’t cut corners and that helps you save time and money.
