Description:
DTH Drill Bits are produced from premium quality nickel-alloy steel for increased durability and wear characteristics. Specific heat treatment standards and special "stress relief" processes ensure consistent performance.
DTH hammer bits are designed for maximum performance and hole cleaning ability and high penetration rate.
Our bits are interchangeable with Atlas Copco's COP32 34 44 54 64 84, Ingersoll-Rand 's DHD3.5, DHD3.5HD, DHD 340A, DHD350R, DHD 360, DHD380 QL40, QL50, QL60, QL80. NUMA100, NUMA120, MISSION60, ects
We export DTH hammer and bits for almost thirty years.
