Powerbit T45 and T51

Secoroc Rock Drilling ToolsNOW ARRIVING. A NEW POWER. Powerbit T45 and T51. POWERBIT. BUILT TO TAKE ON ANY ROCK. We've listened to you, the drillers. You want the drill bits to last longer. You want longer intervals between regrinds. And you want to know which bit is perfect for your rock formation. With Powerbit, our all-new tophammer bit range for surface drilling, you'll get that, and more. Much more. Greatly increased service life Easy bit selection With Powerbit, our development engineers The Powerbit product range covers all have looked at all aspects of drill bit types of rock - from hard to soft, and technology to ensure the longest possible from abrasive to non-abrasive. Thorough service life. The bit shape is all new. We've research, simulation and testing have used harder and stronger bit body steel. And allowed us to make the Powerbit range much our new button technology is so effective more compact and versatile than before. that it's been patented many times over. Approximately 30 % fewer bits now handle all tophammer surface drilling applications – making bit choice so much easier for you. 2 we can proudly state that we now also have the best tophammer drill bits around. Atlas Copco Secoroc has been known to have the best shank adapters and drill rods on the market. Welcome to an unbeatable drill string.A top-of-the-line drill string For years. With Powerbit. 3 .

For most rock formations we offer you up to 15 % more meters between regrinds. With Powerbit you will regrinds. Powerbit – it's long-lasting Longer grinding intervals Our advanced computer simulations. cutting geometries that offer maximum more meters drilled between regrinds. or better.
