Boart Longyear's new BLH5 hammer
Boart Longyear is launching the BLH series of down-the-hole (DTH) hammers and bits.
Designed to increase productivity in reverse circulation drilling and conventional DTH drilling, the new BLH series can be used in almost all DTH applications, including geotechnical drilling, quarrying/mining, water well/geothermal, and mineral exploration.
The BLH DTH hammer range includes the valved BLH5, BLH3, and the valveless BLH1 models. A full line of Boart Longyear DTH bits are available to support the new BLH hammers. “By introducing our
new BLH DTH hammer and bit line, Boart Longyear is simultaneously addressing our customer demand for a DTH solution to increase productivity while increasing our product offering of percussive drilling tools,” says John Nielson, senior product manager for Boart Longyear.
Designed to be compact, the BLH5 hammer reduces its length by 30% and reduces its weight by 20% compared to typical DTH hammers, says Boart Longyear.
