We maintain the largest inventory of reconditioned HDD equipment for all major brands.

Every MTI® drill is put through a detailed 80-point inspection, reconditioned by a team of highly trained mechanics and field tested for quality assurance. That’s our RE-HDD process. Our goal is to find problems and solve them so you don’t have to. That’s how we’re taking the risk out of buying used.
