Down The Hole Hammer Bit

Pneumatic rock drills are ideal for rapidly penetrating hard rock formations by delivering high-frequency impacts directly to the rock layer. With a DTH (Down-The-Hole) hammer, the bit is driven by compressed air, striking the rock with a specific force to shatter it, after which the rock fragments are flushed out by the exhaust air. AGIVA Int’l sells both high-quality DTH hammers and drill bits. In addition to conventional bits, AGIVA Int’l also distributes a specialized hammer bit for driving casing using a concentric drilling system. To prevent premature wear of the down-the-hole hammer, we recommend lubricating it with an inline lubricant every 4 hours.
