Type of Cutters

Rocksmith supply Reverse Circulation Drilling (RCD) Roller Cutters. We have an extensive range of different types and sizes of Tooth Cutters and TCI Button Cutters.

Our RCD cutters feature an internal pressure compensating device to protect the seal from excessive lubrication pressure and heat. And a preloaded bearing provides maximum shock resistance.

Tooth Cutter

Designed and used for drilling soft soil and soft rock layer (0~75MPa) TCI Button Cutter. It was designed and used for drilling hard rock layer (80~250MPa)

8 inch cutters

Our 8" cutters cover the medium drilling range from 750 mm to 1400 mm (30 in to 54 in). Similar to the 12" cutters, the 8" cutters feature a heavy-duty, pressure compensated. A load of up to 80N (18000lbf) per cutter is possible.

12 inch cutters

Our 12" cutters are used for bore holes larger than 1358 mm (54 in). The heavy-duty axle is fitted with combined axial-radial bearings and allows for a thrust force of up to 140KN (31500 lbf) per cutter. The axle square ensures stable and safe positioning of the cutter even in extreme drilling conditions.

Harden RCD Cutter

The R&D team cost over 2 years to research these Harden RCD roller cutters. The biggest difference is harder than traditional RCD roller cutters. They improve the products wear resistance and using time greatly extended (Increased about 20% working life).

Before mass production, R&D team have pay more attention on text them. Now these harder RCD Roller Cutters are large use in milling, rock excavation, tunneling, demolition, recycling and road rehabilitation.

Other Models

Constant design and manufacturing development ensures that highest standard of products. We can offer cutters and drilling tools matched to your requirements and the ground conditions. From 6" Roller Cutters to 14"’ Roller Cutter, we could accord your requirements to manufacture.

Saddle-Holder

10° Saddle-Holder can be set to center part of drilling bit, which makes it possible for a cutter to keep the contacting face of rock horizontal. On the bottom of the saddle, a specially designed groove for location fixing facilitates the change of the saddle on site. In addition it features outstanding wear-resistance due to heat treatment in a contact part.

45° Saddle-Holder is feasible for setting to the edge of drilling bit.
