Raise Boring Cutters
Black Diamond Drilling Raise Bore Cutters have been engineered to include new design features that extend service life and increase the penetration rate of the raise bore system.
A more efficient cutter increases productivity and enhances safety for the operator.
These 14-inch V mounted Cutters are premium cutters with excellent performance in hard rock formations.
Optimised Design
A new improved design features a revolutionary bearing technology that provides a longer cutter life. The new carbides are made from a stronger alloy which reduces wear and breakage in harder ground conditions.
Optimised Design
A longer lasting cutter results in less equipment changes reducing downtime and increasing productivity.

The Black Diamond Drilling Raise Bore Cutters are purpose-built for raise boring in hard rock formations. They deliver an optimized drilling profile with 25mm insert spacing between rows, ensuring a balanced and efficient cutting structure.
Engineered for demanding conditions, these roller cutters excel in angled raises, abrasive ground, and mixed face formations. Their double gage row and double nose row configuration provide superior protection in challenging environments, while strategically placed inserts on gage bevel areas minimize erosion in highly abrasive rock.
Metal face seals, paired with a compact design, enhance both reliability and ease of maintenance.
Backed by advanced engineering and stringent quality control, Black Diamond Drilling consistently delivers performance that exceeds customer expectations.
