Reamers

SlimDril International supply the RockReamer™, one of the most versatile and cost-effective hole openers available for Horizontal Directional Drilling (HDD). Its unique modular design dramatically reduces on-site inventory requirements while maximising flexibility and performance.

The RockReamer™ is designed to push or pull using the same body and cutters, with a single body capable of opening up to six different hole sizes. This significantly reduces downtime, eliminating delays caused by waiting for new tools or cutters when additional reaming is required.

Features & Benefits

Push or Pull with the Same Tool

Designed to perform efficiently in both push and pull reaming operations using the same body and cutter configuration.

Unmatched Versatility

A single RockReamer™ body opens multiple hole sizes, minimising tooling inventory while maximising operational flexibility on site.

Reduced Downtime & Operating Costs

Cutters and arms can be changed easily in the field without the need for torches or welding, reducing trip time, labour, and downtime.

Exceptional Strength & Durability

Stronger than traditional hole openers, the RockReamer™ delivers increased on-bottom rotating time, reducing cutter wear and replacement costs.
