Rebuilt Sandvik Driltech Electronic D55-SP Blasthole Drill

It’s not often we are able to list an exquisite, one of a kind ground up quality rebuilt drill like this Sandvik Driltech D55SP.

The drill was rebuilt by the renowned hydraulic and rebuild specialists at Hy – Performance Fluid Power and what they have been able to achieve in their upgrades and improvements to this Sandvik Driltech D55SP is staggering.

Attention to detail, along with the technological enhancements fitted to this drill offers the operator complete functionality and control over every system and function on the drill.

This is not your standard Driltech D55SP drill, this is a Driltech D55 on steroids and it will change your perception on what is possible in a drill.

The list of quality upgrades and exclusive features is too extensive to be fully appreciated online. We have mentioned the basic details in this description to get you started. For interested buyers we have a comprehensive rebuild overview and specification details available on request.
