The unbeatable productivity of Secoroc COP DTH hammers is all down to innovation. Several ingenious design features, such as our patented air cushion, combine to utilize the air for superior penetration and low air/fuel consumption.
The bit is the tool cutting the rock, and no hammer or rig drilling is better than the bit it uses. The down-the-hole bit is subject to severe stress from the striking piston as well as from the abrasive cuttings passing the bit at high velocity. When selecting the right bit for optimum performance you have to balance penetration against bit life. On occasion you can successfully sacrifice bit life for penetration. In such cases remember the rule of thumb that states that a 10% increase in penetration covers at least a 20% loss in bit life.
Secoroc manufactures their tungsten carbide buttons in-house, right from milling the raw tungsten carbide powder and cobalt, to pressing, sintering and grinding the buttons to a finish. In-house manufacture gives them full control of the production, quality and composition of our bits. With today’s development in rock drilling, where penetration has priority, the ballistic bit design is popular. Nowadays ever harder formations are drilled with ballistic bits.

Tubes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability. These are also the features you’ll find in any Secoroc tube.
Rock drilling can be a demanding business, particularly if the rock is unyielding. One mistake and you’re stuck in the hole, looking grimly at serious downtime. Then it’s too late to wish you had a COP Backhammer. And to think, the cost of one is just a fraction of the cost being without! COP Backhammers can be fitted in a suitable tube joint between the drill support and the rotation head. It provides an effective combination of backward hammering and vibrations.
NOTE! The COP Backhammer comes in 3 1/2′ API Reg threads in both ends.
