WOOKE TOP HAMMER DRILL TOOLS
In Top Hammer Drilling the hammer produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit. The percussive system strikes the drill rod, for example, 2,000-5,000 strikes per minute, and the rotation speed can be, for example, 60-200 rounds per minute. Together these elements make it possible to drill holes in the hard rock. The excess material (cuttings) is flushed up from the bottom of the hole by means of pressurized air or water. Top hammer drills are primarily used in mining, construction, and quarrying of rock material. Top hammer drilling, combined with the “drill and blast” method, makes the whole excavation process extremely efficient.
WOOKE top hammer bits, also commonly referred to as button bits, have been specially designed to drill through almost any type of hard and abrasive rock formations. These drill bits not only have a superior penetration rate compared to their competitors but also a substantially longer service life – up to 30% longer.
