The COP M-series hammers come in three sizes: 6", 7" and 8". By choosing the right hammer, optimum drilling efficiency can be ensured for the entire range of 165 mm to 254 mm bits.
"All the COP M-series hammers show outstanding improvements in penetration rate and service life. COP M7 is particularly successful, since it bridges a known productivity gap between 6" and 8" hammers", Fredrik Gransell continues.
The new, patented air cycle of the COP M-series DTH hammers replaces a design that has been dominant on the market for more than 40 years. This innovation enables a considerably faster cycle, resulting in a shorter, lighter and faster hammer than ever before.
One of the key features is a smaller and shorter piston, which allows the hammer to strike the rock at much higher frequency. At the end of the day, much more impact force has hit the rock, more meters have been drilled, and uniquely enough, the equipment has had a much smoother ride. Finally, the hammers are 25 percent more compact and 30 percent lighter, which make them easier and safer to handle.
The all-new range of DTH bits feature a patented solid shank, a new external airflow system, and special, patented Enduro buttons. As a result, the COP M-series bits drill faster, last longer, and offer longer intervals between regrinds.
"At one gold mining test site, COP M8 bits had a 50 percent longer service life. This is solid proof that our new COP M-series bit technology works even better than expected, says Fredrik Gransell.
Both tests and initial volume production indicate that the COP M-series DTH hammers and bits offer great increases in penetration rate and service life. COP M6, M7 and M8 have proven themselves in all kinds of rock, in all kinds of climates, and with a great variety of drill rigs.
"We are confident that the COP M-series DTH hammers will offer our customers the lowest cost of ownership", concludes Fredrik Gransell.
