Down-the-hole (DTH) hammers and bits from Caterpillar are designed for the most severe blasthole drilling applications, yet they are cost effective for a wide range of drilling needs. The new Cat DTH hammer is 152 mm (6 in.) in diameter and is the first to be introduced in the new DTH line. Its valved design provides reliable operation, low air consumption, easier maintenance and cost-effective rebuild. The piston design delivers long life and efficient energy transfer.
