SECOROC Magnum SR28 - A new addition to the world’s most advanced range of drifting equipment

2002-06-17

The trend in drifting and tunnelling is clear: the rounds are getting longer and the rigs more powerful. Magnum SR was designed to withstand the high pressures so typical of today’s underground drilling operation.

The success of this innovative system is beyond dispute. Drillers using it are not only drilling more and straighter holes than before, they’re also finding that Magnum SR lasts longer than any competing solution. The reason is simple: we’ve added more material at the end of the thread hence the distinctive conical shape, thereby strengthening it significantly.

Advancing rapidly
The latest addition to the family is the SR28 range. This new line replaces the traditional R25 system in 33-35 mm drilling. Tests in rock bolting have shown convincing increases in service life for both the rods and bits. As with all other Magnum SR products, the bits are easy to uncouple, facilitating rapid changes and more holes drilled. This also means that the drillstring is subjected to fewer damaging shockwaves. All together that means less downtime changing bits and rods and more time just drilling.
Magnum SR 35 together with Magnum SR28 is ultimately aimed at helping drillers advance their tunnel or drill bolt holes quicker than ever before.
